B.5 Configuring and Managing OpenVMS Booting on Integrity servers
This section explains how to configure and manage
the booting behavior of your Integrity servers. You can use the EFI
Boot Manager (while the operating system is not running) or the OpenVMS
Integrity servers Boot Manager (while the operating system is running)
to configure boot options. HP recommends using the latter.
You can configure multiple boot entries for a
single operating system. On cell-based Integrity servers running
multiple operating systems, you can configure boot options for all
currently installed operating systems. On cell-based servers, each
nPartition has a local instance of EFI that is specific to that partition.
Each partition can be booted and stopped independently of other nPartitions
in the system, and each partition executes its own operating system
On cell-based servers, to successfully boot an
operating system you must first ensure that the ACPI configuration
is correct for the operating system being booted, as explained in Section B.5.1. Each nPartition has
its own ACPI configuration value.
IMPORTANT: To configure booting on a Fibre Channel storage
device, you must use the OpenVMS Integrity servers Boot Manager utility.
(For information about configuring Fibre Channel devices, see Appendix E.) HP also recommends
using this utility to add members of a multiple-member shadow set
to the boot device list and dump device list. Be sure to add all
members to both lists.
If you have just completed the initial setup of
your Integrity servers, perform the following steps before continuing:
up your server system, as explained in the hardware documentation
for your server. If you use the power button on the front panel,
press it only once.
NOTE: If you see a warning that the BMC system event
log (SEL) is full, you can safely continue by following the prompts;
OpenVMS processes the contents of the SEL. If you want to clear the
SEL manually, see the instructions in the first note of Section B.6.
HP recommends that you load and use the most current
system firmware. For more information about updating the system firmware,
see Section 1.3.6.
you have a cell-based server, check that the ACPI configuration is
correct for the OpenVMS operating system. For more information, see Section B.5.1.
At the EFI Boot Manager menu, select the EFI Shell [Built-in] option.
You can now boot your OpenVMS Integrity servers system manually,
or you can add a new entry to the EFI Boot Manager menu to have your
system booted automatically whenever you power on your Integrity servers
This section discusses the following topics:
Checking the ACPI configuration for nPartition booting
Setting automatic booting and boot flags for your
system disk (Section B.5.2)
(also includes how to set automatic booting using EFI commands)
Displaying EFI boot entries and mapped OpenVMS devices,
using the OpenVMS Integrity servers Boot Manager utility (Section B.5.2.2) (also includes how
to display boot entries using EFI commands)
Setting the EFI boot option timeout value, using the
OpenVMS Integrity servers Boot Manager utility (Section B.5.2.3)
Writing a new boot block, using the OpenVMS Integrity
servers SET BOOTBLOCK command (Section B.5.3)
Comparing Alpha and Integrity servers system boot
commands (Section B.5.4)
B.5.1 Checking the ACPI Configuration for Booting OpenVMS in an nPartition
To boot your OpenVMS Integrity servers operating
system on a cell-based server, the ACPI configuration must be set
correctly. The ACPI configuration value determines, among other things,
the EFI Path format used when referencing devices. If your Integrity
servers was factory installed, the ACPI configuration is set correctly.
If the nPartition on which you want to boot your OpenVMS system had
previously been running a Windows or Linux system, then enter the
following command at the EFI Shell prompt to set the partition to
boot correctly with OpenVMS:
EFI> acpiconfig default
To make this new value take effect, you must reset
the nPartition by using the EFI Shell reset command:
If the ACPI configuration value is not set properly,
when the operating system boots, it fails with bugcheck code INCONSTATE.
You cannot modify the ACPI configuration value
for Integrity servers that do not support nPartitions (for example,
the rx2600 server).
To display the current configuration value, enter
the acpiconfig command with no arguments:
EFI> acpiconfigAcpiconfig settings: default
NOTE: The acpiconfig command does not necessarily
report the setting that was used on the current nPartition boot stage.
It reports only the current setting, which is used for the next boot
of the nPartition.
B.5.2 Setting Boot Options for Your System Disk
You can establish and manage boot options for
your system disk in any of three ways:
During installation or upgrade, allowing the OpenVMS
Integrity servers installation/upgrade procedure to automatically
establish an EFI boot option for your system disk
Using the OpenVMS Integrity servers Boot Manager utility
(SYS$MANAGER:BOOT_OPTIONS.COM) while the operating system is running
Using EFI (after the system disk has been created
or updated and only while the operating system is not running)
HP recommends that you allow the OpenVMS Integrity
servers installation or upgrade procedure to establish a boot option
for your system disk. However, you still have the option of modifying
the boot option or adding other boot options for your system disk
by using the OpenVMS Integrity servers Boot Manager utility from the
OpenVMS DCL prompt (or by using EFI itself).
The OpenVMS Integrity servers Boot Manager utility
is a menu-based utility that enables you to configure EFI boot options
for your Integrity servers. It is easier to use than EFI. With this
OpenVMS utility, you can perform actions such as the following:
Add your system disk as an EFI boot option (you can
optionally configure it to boot automatically on hardware startup
Manage multiple system disks.
Set boot flags.
Display the EFI boot options.
Add, move, and remove boot options in the EFI Boot
Enable or disable the EFI boot countdown timer (timeout)
and set the countdown value.
This section explains how to perform most of these
operations (except moving and removing boot options). For more information
about the OpenVMS Boot Manager utility, see the HP OpenVMS
System Manager's Manual, Volume 1: Essentials. This section
also explains how to use EFI to add a boot option for automatic booting.
HP recommends that you configure your system with a boot
option for your system disk. You can enable automatic reboot of the
system disk by specifying your system disk as the first boot option
in the EFI Boot Manager menu. When the EFI timeout (countdown) occurs,
your system disk boots automatically.
NOTE: To configure booting on Fibre Channel devices,
you must use the OpenVMS Integrity servers Boot Manager utility.
(Use of this utility is optional for other devices but mandatory for
Fibre Channel devices.) HP also recommends using this utility to
add members of a multiple-member shadow set to the boot device list
and dump device list. Be sure to add all members to both lists.
For more information about the utility, see the HP OpenVMS
System Manager's Manual, Volume 1: Essentials. For more
information about configuring and booting Fibre Channel devices, see Appendix E.
B.5.2.1 Adding a Boot Option and Setting Boot Flags
To add a boot option and set boot flags using
the OpenVMS Integrity servers Boot Manager utility, follow these steps:
the DCL prompt, enter the following command to start the OpenVMS Integrity
servers Boot Manager utility:
the utility starts, the main menu is displayed. To add your system
disk as a boot option, enter 1 at the prompt, as in the following

01. VenHw(d65a6b8c-71e5-4df0-d2f009a9) "EFI Shell [Built-in]"
1 entries found.
Enter the desired position number (1,2,3,...) of the entry.
To display the Boot Options list, enter "?" and press Return.
Position : 1
utility prompts you for OpenVMS boot flags. By default, no flags
are set. Enter the OpenVMS flags (for example, 0,1), or press Enter to set no flags, as in the following example:
Enter the value for VMS_FLAGS in the form n,n.
Optionally, you can use any of the standard OpenVMS
boot flags such as the following:
Enable SYSBOOT to change system parameters; enable conversational
booting for debugging purposes.
Take the initial EXEC_INIT breakpoint.
Print debug messages on boot.
Print more debug messages on boot.
utility prompts you for a description to include with your boot option
entry. By default, the device name is used as the description. You
can enter more descriptive information as in the following example.
This example shows a sample confirmation message (for devices with
multiple paths, such as Fibre Channel devices, a separate confirmation
message is displayed for each path). EFI$BCFG is the name of the
executor file for the OpenVMS Integrity servers Boot Manager utility.
Enter a short description (do not include quotation marks).

B.22.214.171.124 Using EFI to Set Automatic Booting of Your System Disk
HP recommends allowing the OpenVMS installation
or upgrade procedure to set your system disk to boot automatically.
Or, use the OpenVMS Integrity servers Boot Manager utility (SYS$MANAGER:BOOT_OPTIONS.COM).
However, you can use EFI. This section explains how to use EFI to
set up your Integrity servers firmware to automatically boot your
OpenVMS Integrity servers system from your system disk. (HP also
recommends using the OpenVMS Integrity servers Boot Manager utility
to set boot flags. Optionally, you can use the vms_loader.efi
-flags n,n command at the EFI prompt to set any of the standard
OpenVMS boot flags, as documented earlier in this appendix.)
Access the EFI Shell and enter the following line
at the prompt, where fsn: (such as fs0: or fs1:)
is the device associated with the system disk:
This command adds the OpenVMS Integrity servers
operating system to position 1 in the EFI Boot Manager menu. The
quoted text in the command line (“HP OpenVMS Integrity servers”)
is displayed at position 1 in the EFI boot menu. You can enter any
text that helps you identify the operating system disk. During system
power up, the position 1 item is automatically executed after the
Alternatively, you can add an EFI boot menu option
by using the EFI menu interface:
the Boot Configuration option (or in some versions of EFI, the Boot
Option Maintenance Menu).
Add a Boot Option.
the boot device and boot file.
NOTE: All EFI boot options embed the disk Globally Unique
ID (GUID). Therefore, if you reinstall OpenVMS or restore a system
disk from an image backup, you must first delete the old boot options
and then add a new boot option. To delete a boot option, use the
Delete Boot Option(s) option in the Boot Configuration menu (or Boot
Option Maintenance Menu).
Still another method to add a boot entry to the
EFI Boot Manager menu is to use the EFI Utilities for OpenVMS (Integrity servers only)vms_bcfg command, which accepts OpenVMS device names and also enables you
to set flags. However, this command has limited capabilities; for
example, it cannot handle Fibre Channel paths as can the OpenVMS Integrity
servers Boot Manager utility. In the following example, DKA0: is the
OpenVMS system disk being added as the first boot option:
For more information about EFI utilities for OpenVMS,
see the HP OpenVMS System Management Utilities Reference
B.5.2.2 Displaying EFI Boot Entries and Mapped OpenVMS Devices
The Integrity servers EFI Boot Manager shows the
various paths to the boot device. You can use the OpenVMS Integrity
servers Boot Manager utility to display the OpenVMS boot device options
known to EFI.
Start the utility at the DCL prompt (@SYS$MANAGER:BOOT_OPTIONS.COM)
and select option 2 on the main menu (the main menu is shown in Section B.5.2). The utility displays
the following prompt. In this example, the listings for the DQA0:
device are requested and displayed.
To display all entries in the Boot Options list, press Return.
To display specific entries, enter the entry number or device name.
(Enter "?" for a list of devices): DQA0EFI Boot Options list: Timeout = 20 secs.
04. DQA0 PCI(0|0|2|0) ATA(Primary,Master) "DVD-ROM "
1 entries found.
You can also display all bootable devices mapped
by the EFI console and their equivalent OpenVMS device names by using
the EFI Utilities for OpenVMS vms_show command
at the EFI Shell prompt (from \efi\vms). For more
information about EFI utilities for OpenVMS, see the HP
OpenVMS System Management Utilities Reference Manual.
Whenever the EFI Boot Manager menu displays, it waits for you to
select an option. The wait depends on the current setting of the
EFI countdown timer. On some servers, the countdown timer
is 10 seconds by default; on others, such as Server Blade products,
it might be even less. After the timer expires, EFI boots the first
boot option. If the first option is not available or does
not boot, EFI waits the same duration before booting the next option
in the list. The OpenVMS Integrity servers Boot Manager utility
(SYS$MANAGER:BOOT_OPTIONS.COM) allows you to change this timeout value
and also to disable the countdown (so that there is no wait) and enable
Select option 6 on the OpenVMS Integrity servers
Boot Options main menu (the main menu is shown in Section B.5.2). The utility displays
the following prompt. To change the value, enter YES and then enter
the new value. In this example, the timeout value is changed to 20
efi$bcfg: Boot Timeout period is 10 secs
Would you like to modify the Timeout value? (Yes/No) [NO] YESPlease enter the Timeout value in seconds: 20
efi$bcfg: Boot Timeout period is 20 secs
To disable the timer so that automatic booting
occurs instantaneously, enter 0 as the value, as in the following
Please enter the Timeout value in seconds: 0
efi$bcfg: Boot Timeout is Disabled
B.5.2.4 Saving and Restoring EFI Settings
Certain EFI settings, such as the Hyper-Threading
setting supported on Intel Itanium Dual-Core processors, cannot be restored if lost. HP recommends that you write down your
customized EFI settings in case they are lost in a system hardware
or firmware failure. You can use the EFI info cpu command or the EFI cpuconfig command to display
current settings, such as the setting of the Hyper-Threading feature.
You might need to restore boot options, such as
if they get lost during a firmware upgrade. You can save and restore
your EFI boot path settings on Integrity servers by using the OpenVMS
Integrity servers Boot Manager (SYS$MANAGER:BOOT_OPTIONS.COM) utility.
You can also use the EFI variable -s command to
save boot option variables and the variable -r command
to restore them. After using the variable command
to restore boot options, a reset might be required. Use the EFI Shell reset command.
You can use the OpenVMS-specific EFI utility vms_bcfg (\efi\vms\vms_bcfg) to set boot options, and the vms_show utility (\efi\vms\vms_show) to display them; however,
these utilities are more limited in scope than the OpenVMS Integrity
servers Boot Manager utility. For example, they cannot work with Fibre
Channel boot paths as can the OpenVMS Integrity servers Boot Manager
utility. You can use the EFI variable command to
restore the boot options list from a previously saved file.
You could also use the EFI Shell variable command to restore variables such as boot path options; you must
have first saved them in a known location by using the variable
-save command. For more information, see the service manual
provided for your Integrity servers.
B.5.3 Writing a New Boot Block
The boot block structures on the system disk contain
the size and location of the boot partition and other details relevant
to the bootstrap of OpenVMS Integrity servers. The size and location
of the boot partition stored within the boot block structures must
be maintained and must reference the current location of the OpenVMS
Current versions of BACKUP maintain the boot block
structures as well as the size and location of the boot partition
during image operations (analogous to the similar BACKUP/IMAGE operations
that maintain the boot block on OpenVMS Alpha disks). Older versions
of BACKUP do not maintain these structures and do not correctly locate
core OpenVMS Integrity servers bootstrap files.
If the boot partition file SYS$EFI.SYS is manually
replaced or relocated, you must use the DCL command SET BOOTBLOCK
or the SYS$SETBOOT image to rewrite the boot block structures. The
SET BOOTBLOCK command and SYS$SETBOOT are analogous to the OpenVMS
Alpha Writeboot utility; they provide OpenVMS Integrity servers with
the equivalent of what the Writeboot utility provides on OpenVMS Alpha.
NOTE: Do not use the OpenVMS Alpha Writeboot utility to rewrite boot
block structures on an OpenVMS Integrity servers system disk.
The SET BOOTBLOCK command enables you to establish
the boot block pointers necessary for the EFI console to find and
bootstrap an OpenVMS Integrity servers system disk. You must use
this command if the target OpenVMS Integrity servers system disk was
originally created by one of the following methods:
A version of BACKUP that
does not support the OpenVMS Integrity servers system disk structure.
HP recommends that you do not use these versions
of BACKUP for archiving or restoring an OpenVMS Integrity servers
A nonimage backup of an
OpenVMS Integrity servers system disk (possibly corrupting the boot
block and various directory backlinks that must be manually reset).
HP recommends that you do not use nonimage backups.
A nonimage restore of
an OpenVMS Integrity servers system disk from an image save set.
HP recommends that you do not use a nonimage
NOTE: If the target OpenVMS Integrity servers system
disk has an incorrectly-placed GPT.SYS file, the disk cannot
be used reliably as an OpenVMS Integrity servers system disk. Typically,
the file gets incorrectly placed due to the use of an older version
of BACKUP/IMAGE, a file-based BACKUP disk restoration, or an errant
disk defragmentation tool (the file is set with /NOMOVE to disable
move operations; defragmentation tools that do not honor this setting
will corrupt the file). A correctly-located GPT.SYS file will have
at least two file extents, the first beginning at LBN 0 and the last
at the disk capacity minus the size of the last extent (an extent
is one or more adjacent clusters allocated to a file). The size of
each of the two extents varies according to the disk cluster factor
on the target disk. The first extent size is currently 34 or more
blocks, and the last extent 33 or more blocks. For example:
This example is from a disk with 71132960 blocks.
The placement of the final extent is 71132924, which is calculated
by subtracting 36 (the size of the last extent) from the disk capacity
You may be able to temporarily recover from this
condition and attempt to bootstrap the target OpenVMS Integrity servers
system disk by renaming GPT.SYS to GPT.BAD, and then entering the
SET BOOTBLOCK command. To correctly recover from this condition,
you must INITIALIZE the target disk and then reload the disk contents
using a file-based BACKUP restoration or a file-based COPY operation.
No supported means exists for adding a GPT.SYS file onto an existing
disk nor for adding the file during a BACKUP/IMAGE restoration operation.
To write the boot block structures onto an OpenVMS
Integrity servers system disk, enter the SET BOOTBLOCK command using
the following format:
$ SET BOOTBLOCK [/PRESERVE=SIGNATURES] [/I64] [boot-partition-name]
You can specify the file name for the boot partition
(boot-partition-name). If you do not specify
a file or device name, the command defaults to the following file
for the boot partition:
The command also assumes the current architecture.
To specify OpenVMS Integrity servers, include /Integrity servers
in the command line.
Use the /PRESERVE=SIGNATURES qualifier to preserve
the existing GUID disk signature value and the associated root aliases.
Using the OpenVMS Backup utility creates a new disk signature when
restoring a bootable disk image.
If you reset the boot block structures, you might
need to remove any EFI boot aliases that reference the disk, and then
add them back again. You can use the EFI alias command to remove and add aliases; HP recommends using the OpenVMS
Integrity servers Boot Manager utility (SYS$MANAGER:BOOT_OPTIONS.COM)
to maintain EFI console boot aliases.
NOTE: The boot partition file must be contiguous and movefile operations
on the file must be disabled. If the file is not contiguous, use
the DCL command COPY/CONTIGUOUS (or equivalent) to re-create a contiguous
version of the file. To disable movefile operations, use the DCL
command SET FILE/NOMOVE. This prevents bootstrap failures that could
result from the normal and expected operations of disk defragmentation
Alternatively, you can write a boot block by entering
the following command:
$ RUN SYS$SYSTEM:SYS$SETBOOT
The utility prompts you for the required input
(in a way similar to the operation of the OpenVMS Alpha Writeboot
B.5.4 Alpha and Equivalent Integrity servers System Boot Commands
Firmware Interface (EFI) on Integrity servers performs most of the
same functions that the SRM console does on Alpha processors. If
you are familiar with the Alpha tool, use the following table to find
EFI commands equivalent to the Alpha commands you commonly use on
Alpha systems. Some of the commands listed might not be available
on certain hardware systems.

 Similar functionality is provided by the OpenVMS Integrity servers
Boot Manager utility (SYS$MANAGER:BOOT_OPTIONS.COM), launched at the
OpenVMS DCL prompt. Regarding the display of devices, BOOT_OPTIONS.COM
displays only the boot entries and also a selected dump device for
DOSD and a debug device; vms_show can display all
devices mapped by the EFI console and their equivalent OpenVMS device
names. The map command shows all devices currently
mapped on the EFI Shell.
 Best source of information about power status is the MP PS command.
