EFI is the basic interface
between the operating system and firmware on all Integrity server
systems, similar to SRM (P00>) on Alpha systems. EFI provides
a boot option menu and the ability to configure boot options.When
you first power on a new Integrity server system, you first see
a series of diagnostic messages followed by the EFI Boot Manager
screen unless MP is available. The following is an example of an
initial EFI Boot Manager screen. (On some systems that include MP,
you might first see the MP login screen described in
Using the Management Processor (MP) Interface. As noted at the beginning
of this appendix, the behavior of Integrity server systems can vary
significantly from model to model as well as from version to version.)
The
system pauses 10 seconds to allow you to select an option. If you
do not select an option in that time, EFI takes you to the first
option on the list, the EFI Shell (you see the EFI Shell prompt).
However, if your Integrity server came with the OpenVMS I64 operating
system factory installed (FIS), then the OpenVMS I64 operating system is the
first option and it boots automatically.
To select an option from the EFI Boot Manager menu, use the
up or down arrow key to highlight an item, and then press Return to
activate the selection. You can use EFI to configure numerous options
for your Integrity server and OpenVMS operating system; however,
HP recommends that you use the OpenVMS I64 Boot Manager (BOOT_OPTIONS.COM)
utility after you have installed and started running the OpenVMS
I64 operating system, as described in
Configuring and Managing Booting of Your Integrity server.
In any case, for the first boot of a system on which OpenVMS
is not preinstalled, you will probably need to use EFI to get started.
When you select the EFI Shell, the interface displays a list of
file systems (fs drives and partitions) and block devices (blk),
followed by the EFI Shell> prompt, as in the following
example. If you do not see the EFI Shell> prompt, press
Return (note also that the EFI Shell prompt may have changed, as explained
in
General Tips and Notes on Using EFI). The drives
and devices are described in more detail in
Booting the New OpenVMS I64 System Disk.
If you are booting from the OpenVMS I64 Operating Environment
DVD and no other systems are present on any of your Integrity server's
disks, the DVD is usually associated with fs0:. You can boot the
DVD to start installing OpenVMS onto a system disk by following
the directions provided in
Booting the OpenVMS I64 Operating System Kit.
After installing
the system, you can use the OpenVMS I64 Boot Manager (BOOT_OPTIONS.COM)
utility to set up EFI to boot the new system disk automatically
whenever the Integrity server is powered on or the system is rebooted.
This utility is easier to use than EFI and allows you to configure
the most pertinent options for your system, including the following:
Display boot options known
to the EFI Boot Manager
Add a boot option to the
EFI Boot Manager so that your system disk boots automatically when
the system is powered on or rebooted
Remove or change the position
of a boot option in the EFI Boot Manager list
Validate and fix the boot
option list
Change how long EFI pauses
before booting or rebooting
Use of this utility is optional for most devices but is required
for configuring boot options on Fibre Channel devices. For instructions
on how to use the utility, see
Configuring and Managing Booting of Your Integrity server. For more information about configuring Fibre
Channel devices with this utility, refer to the Guidelines for OpenVMS Cluster Configurations. Information about using the
OpenVMS I64 Boot Manager utility to display boot options is provided
in
Displaying EFI Boot Entries and Mapped OpenVMS Devices. For information
about setting the pause length, see
Setting EFI Boot Option Timeout. The OpenVMS I64 Boot Manager utility also allows
you to configure Dump Off the System Disk (DOSD) devices and Debug
devices; for more information about this, refer to the HP OpenVMS System Manager's Manual, Volume 2: Tuning, Monitoring, and Complex Systems.
General
Tips and Notes on Using EFI Note the following:
To switch to a different file system, enter the
file system name, as in the following example showing how to switch
to fs3: from the current location (top level of the EFI Shell):
Shell> fs3:
fs3:\>
Once you move from the Shell> prompt to a specified
file system location, the EFI Shell prompt will be the name of the
file system as in the example shown. The Shell> prompt
displays again if you reset the system.
The file structure of an fs disk is identical to
MS-DOS and the commands to move around the structure are similar
to MS-DOS commands. For example, to move to directory efi on disk
fs0:, enter the cd command as follows:
fs0:\> cd efi
fs0:\efi>
To display the contents of the efi directory, use the dir command.
Most commands that you issue for OpenVMS purposes at
the EFI Shell prompt are issued from \efi\vms on
the file system associated with the system disk. You can enter such
commands directly from the top level by specifying \efi\vms
in the path for subsequent commands, or by first moving to \efi\vms
and entering the commands without the path specification. The first
example that follows shows how to enter commands from the top level.
The second example shows how to move to \efi\vms
before issuing the commands. The vms_show command displays the equivalent OpenVMS device name for
devices mapped by EFI and the vms_set command can be used to set a debug or dump device. These
EFI commands for OpenVMS, known as EFI Utilities for OpenVMS, are usable
only when the operating system is not running. To display and set
EFI-mapped devices while the system is running, use the OpenVMS
I64 Boot Manager (BOOT_OPTIONS.COM), as described in
Configuring and Managing Booting of Your Integrity server. The EFI Utilities for OpenVMS
are described in detail in the HP OpenVMS System Management Utilities Reference Manual.
The directory structure and contents of the OpenVMS
system disk differs from that of the OpenVMS I64 Operating Environment
DVD. Note also that the bootstrap on the system disk is located
at \efi\vms\vms_loader.efi while on the DVD it is at \efi\boot\bootia64.efi.
You can define aliases for EFI commands that are
easier to remember. For example, to define the alias dir for the ls command, use the alias command as in the following example:
fs0:\> alias dir "ls"
To define an alias for the command that boots OpenVMS from
fs0:, you would type the following command:
fs0:\> alias bvms "fs0:\efi\vms\vms_loader.efi"
Setting an alias to point to a specific
device as in this example could lead to unexpected results. For
example, if you insert a DVD in the DVD/CD drive, fs0: will now
point to the DVD/CD drive. HP recommends using the OpenVMS I64 Boot
Manager to set your system disk as a boot device, as explained
in
Configuring and Managing Booting of Your Integrity server.
To list the aliases currently defined, enter the alias command, as shown:
fs0:\> alias dir : ls bvms : fs0:\efi\vms\vms_loader.efi
If your system has a large number of file systems,
when EFI lists the file systems and block devices at startup, you
might only see the last portion of the list (probably the block
devices). To see the entire list, enter the exit command at the EFI Shell prompt. You are then brought
to the EFI Boot Manager screen. From there, reenter the EFI Shell
to see all the devices.
The boot devices listed in
the EFI Boot Manager menu are linked to a specific serial number
(listed in the device mapping table) not to the fs number (fs0 or
fs1, for example). Thus, if you use a copy of a boot disk, the boot
entry (corresponding to the original boot disk) in the EFI Boot
Manger menu will not work. You would have to remove that boot option
entry and reset the system (enter the reset command at the EFI Shell prompt).
To move from MP interface to EFI, type CO (Console)
at the MP> prompt.
To move from the BMC interface to EFI, press the
Esc key followed by entering the BMC Q command.
To move from the EFI to MP, press Ctrl/B (this assumes
MP is present and configured).
To move from the EFI to BMC, press the Esc key followed
by the left parenthesis character [(] (Shift/9).
For more information about using
EFI, refer to the documentation provided with your Integrity server.
