RESERVED_MEMORY REMOVE (Alpha and I64)
On Alpha and I64 systems, removes a reserved memory entry from the
Reserved Memory Registry data file. This command takes effect on the
next reboot and does not affect the running systems.
Format
RESERVED_MEMORY REMOVE name
Parameter
name
Name associated with the entry being removed. You must specify a name.
If page tables are reserved for the named memory-resident global
section, the additional reserved memory is also removed.
Qualifiers
/GLOBAL_SECTION (default)
/NOGLOBAL_SECTION
/NOGLOBAL_SECTION indicates that the memory qualifier is for a
privileged application instead of a group or system global section.
(/GLOBAL_SECTION indicates that the memory qualifier is for a group or
system global section.) You cannot use /NOGLOBAL_SECTION with the
qualifiers /GROUP, /SYSGBL, or /PAGE_TABLES.
/GROUP=n
You must specify /GROUP if the memory-resident global section is a
group global section. Do not specify /GROUP if the memory-resident
global section is a system global section. The value n is the
UIC group number (in octal) associated with the memory-resident section
being removed. You cannot use the /GROUP qualifier with either /SYSGBL
or /NOGLOBAL_SECTION parameters.
/SYSGBL
Indicates that a reservation is for a system global memory resident
section.
You cannot combine this qualifier with the /GROUP or /NOGLOBAL_SECTION
qualifier. This qualifier is the default unless you specify /GROUP or
/NOGLOBAL_SECTION.
Example
|
SYSMAN> RESERVED_MEMORY ADD DFW$GS1/SIZE=1
SYSMAN> RESERVED_MEMORY REMOVE DFW$GS1
|
The first command in this example adds DFW$GS1; the second command
removes it.
RESERVED_MEMORY SHOW (Alpha and I64)
On Alpha and I64 systems, displays the memory reservations on the
running system.
The display includes how much of the reserved memory is currently in
use by the named global section. It also includes how much memory is
reserved and currently in use for page tables, if any, and the blocks
of physical pages reserved.
Format
RESERVED_MEMORY SHOW name
Parameter
name
Name associated with the entry being displayed within the running
system. If you do not specify a name, the system displays the
reserved memory for all registered global sections.
Qualifiers
/GLOBAL_SECTION (default)
/NOGLOBAL_SECTION
/NOGLOBAL_SECTION indicates that the memory qualifier is for a
privileged application instead of a group or system global section.
(/GLOBAL_SECTION indicates that the memory qualifier is for a group or
system global section.) You cannot use /NOGLOBAL_SECTION with the
qualifiers /GROUP, /SYSGBL, or /PAGE_TABLES.
/GROUP=n
You must specify /GROUP if the memory-resident global section is a
group global section. Do not specify /GROUP if the memory-resident
global section is a system global section. The value n is the
UIC group number (in octal) associated with the memory-resident section
being displayed. You can use the /GROUP qualifier only if you specify
name. You cannot use the /GROUP qualifier with either /SYSGBL
or /NOGLOBAL_SECTION parameters.
/SYSGBL
Indicates that a reservation is for a system global memory resident
section.
You cannot combine this qualifier with the /GROUP or /NOGLOBAL_SECTION
qualifier. This qualifier is the default unless you specify /GROUP or
/NOGLOBAL_SECTION.
Example
|
SYSMAN> RESERVED_MEMORY SHOW
%SYSMAN-I-OUTPUT, command execution on node PIPER
Name Pages In Use Group PTs Alloced Zeroed
DFW$GS_3 384 0 SYSGBL No No No
DFW$GS_2 256 0 SYSGBL No Yes Yes
DFW$GS_1 128 0 00000100 No No No
DFW$GS_3 1 0 SYSGBL Yes No No
DFW$GS_2 1 0 SYSGBL Yes Yes No
|
The command in this example displays the memory reservations on a
running system.
SET ENVIRONMENT
Defines the nodes or cluster to which subsequent commands apply.
Requires OPER or SETPRV privilege on all nodes in the target
environment.
Format
SET ENVIRONMENT
Parameters
None.
Qualifiers
/CLUSTER
Specifies that all subsequent commands apply to all nodes in the
cluster. By default, the management environment is the local cluster.
Specify a nonlocal cluster by naming one cluster member with the /NODE
qualifier.
/NODE=(node1,node2,...)
Specifies that SYSMAN execute subsequent commands on the given DECnet
nodes. If accompanied by the /CLUSTER qualifier, the environment
becomes the cluster where the given DECnet node is a member. A node
name can be a system name, cluster alias, or logical name. However,
before you can use logical names to define the command environment, you
must set up the logical name table SYSMAN$NODE_TABLE. For more
information about defining the SYSMAN logical name table, see the
HP OpenVMS System Manager's Manual.
/USERNAME=username
Specifies that this user name should be used for access control
purposes on another node. You can use this qualifier only in
conjunction with the /CLUSTER or /NODE qualifiers. SYSMAN uses the
current user name if none is supplied. SYSMAN prompts for a password
whenever you specify a new user name.
Note
The account specified must have only a primary password. Accounts with
secondary passwords are not supported.
|
Description
The SET ENVIRONMENT command defines the target nodes or cluster for
subsequent commands. When invoked, the system management environment is
the local node where you are running SYSMAN. You can change the
environment to any other nodes in the cluster, the entire cluster, or
any nodes or cluster available through DECnet.
Designate an OpenVMS Cluster environment with the /CLUSTER qualifier.
When specifying a nonlocal cluster, also include the /NODE qualifier to
identify the cluster.
If your environment consists of VAX, Alpha, and I64 nodes, see the DO
command for information about creating logicals to manage each platform
as an environment.
You can display the current environment with the command SHOW
ENVIRONMENT. To adjust privileges and defaults for the current
environment, use the SET PROFILE command.
An environment exists until you exit from SYSMAN or establish another
command context with the SET ENVIRONMENT command.
Examples
| #1 |
SYSMAN> SET ENVIRONMENT/CLUSTER
%SYSMAN-I-ENV, Current command environment:
Clusterwide on local cluster
Username ALEXIS will be used on nonlocal nodes
|
This command defines the command environment as the local cluster.
SYSMAN confirms the new environment.
| #2 |
SYSMAN> SET ENVIRONMENT/NODE=NODE21/CLUSTER
Remote Password:
%SYSMAN-I-ENV, Current command environment:
Clusterwide on remote node NODE21
Username ALEXIS will be used on nonlocal nodes
|
This command establishes a management environment on the cluster where
NODE21 is a member. SYSMAN prompts for a password because it is a
nonlocal environment.
| #3 |
SYSMAN> SET ENVIRONMENT/NODE=(NODE21,NODE22,NODE23)
%SYSMAN-I-ENV, Current command environment:
Individual nodes: NODE21,NODE22,NODE23
Username ALEXIS will be used on nonlocal nodes
|
This command defines the management environment to be three individual
nodes.
| #4 |
$ CREATE/NAME_TABLE/PARENT=LNM$SYSTEM_DIRECTORY -
_$ SYSMAN$NODE_TABLE
$ DEFINE LAVCS SYS1,SYS2,SYS3,SYS4/TABLE=SYSMAN$NODE_TABLE
$ RUN SYS$SYSTEM:SYSMAN
SYSMAN> SET ENVIRONMENT/NODE=(LAVCS)
%SYSMAN-I-ENV, Current command environment:
Individual nodes: SYS1,SYS2,SYS3,SYS4
Username ALEXIS will be used on nonlocal nodes
|
The commands in this example set up the logical name table
SYSMAN$NODE_TABLE, define a logical name (LAVCS), and use the logical
name to define the command environment.
SET PROFILE
Temporarily modifies a user's current privileges and default device and
directory.
Format
SET PROFILE
Parameters
None.
Qualifiers
/DEFAULT=device:[directory]
Specifies the default disk device and directory name that the system
should use in this environment to locate and catalog files.
/PRIVILEGES=(priv1,priv2...)
Specifies the privileges to add to the current privileges. Any enhanced
privileges must be authorized.
/VERIFY
/NOVERIFY (default)
Specifies whether you want DCL verification (both procedure and image)
for future DO commands.
Description
The SET PROFILE command modifies process attributes for the current
management environment. After considering the privilege requirements of
commands that you intend to use in an environment, you can add or
delete current privileges, if they are authorized. You can also set a
new default device and directory, as well as use the SET
PROFILE/[NO]VERIFY command to control DCL command verification in
SYSMAN. Other attributes of your process remain constant. The profile
is in effect until you change it, reset the environment, or exit from
SYSMAN. The HP OpenVMS System Manager's Manual discusses profile changes in more detail.
Examples
| #1 |
SYSMAN> SET PROFILE/DEFAULT=WORK1:[ALEXIS]
|
This command changes the default device and directory in the user
account to directory ALEXIS on device WORK1.
| #2 |
SYSMAN> SET PROFILE/PRIVILEGES=(SYSPRV,CMKRNL)/VERIFY
|
This command makes the authorized privileges, SYSPRV and CMKRNL, part
of the current privileges, and turns on DCL verification. The
privileges remain in effect until the environment changes, you enter
another SET PROFILE command, or you exit.
SET TIMEOUT
Establishes the amount of time SYSMAN waits for a node to respond. Once
the time limit expires, SYSMAN proceeds to execute the command on the
next node in the environment.
Format
SET TIMEOUT time
Parameter
time
Specifies a delta time value, which has the following format:
This is the amount of time that SYSMAN waits for a node to respond.
SYSMAN waits indefinitely---by default it has no timeout period. Refer
to the OpenVMS User's Manual for a description of delta time values.
Qualifiers
None.
Example
|
SYSMAN> SET TIMEOUT 00:00:30
%SYSMAN-I-TIMEVAL, timeout value is 00:00:30
SYSMAN> CONFIGURATION SHOW TIME
System time on node NODE21: 19-JUN-2002 14:22:33
%SYSMAN-I-NODERR, error returned from node NODE22
%SMI-E-TIMEOUT, remote operation has timed out
System time on node NODE23: 19-JUN-2002 14:23:15
|
This command establishes a timeout period of 30 seconds. Because NODE22
did not respond within 30 seconds, SYSMAN displays an error message and
proceeds to execute the command on the next node in the environment.
SHOW ENVIRONMENT
Displays the target nodes or cluster where SYSMAN is executing commands.
Format
SHOW ENVIRONMENT
Parameters
None.
Qualifiers
None.
Description
The SHOW ENVIRONMENT command displays the current management
environment. It can be the local cluster, local or remote nodes, or a
nonlocal cluster. SYSMAN indicates if the environment is limited to
individual nodes or if it is clusterwide. It also shows the current
user name.
The environment exists until you exit from SYSMAN or enter another SET
ENVIRONMENT command.
Examples
| #1 |
SYSMAN> SHOW ENVIRONMENT
%SYSMAN-I-ENV, Current command environment:
Clusterwide on local cluster
Username ALEXIS will be used on nonlocal nodes
|
This command shows the current environment is the local cluster. User
name ALEXIS will be used on other nodes in the cluster.
| #2 |
SYSMAN> SHOW ENVIRONMENT
%SYSMAN-I-ENV, Current command environment:
Clusterwide on remote cluster NODE21
Username ALEXIS will be used on nonlocal nodes
|
This command shows that the command environment is a nonlocal cluster
where NODE21 is a member.
| #3 |
SYSMAN> SHOW ENVIRONMENT
%SYSMAN-I-ENV, Current command environment:
Individual nodes: NODE22,NODE23
At least one node is not in local cluster
Username ALEXIS will be used on nonlocal nodes
|
This command shows that the command environment consists of two nodes.
SHOW KEY
Displays key definitions created with the DEFINE/KEY command.
Format
SHOW KEY [key-name]
Parameter
key-name
Specifies the name of the key whose definition you want displayed. See
the DEFINE/KEY command for a list of valid key names.
Qualifiers
/ALL
Displays all the key definitions in the specified state or states.
Specifying a key name is not necessary.
/BRIEF
Displays only the key definition. By default, the system displays all
the qualifiers associated with the key definition, including any
specified state, unless you use the /BRIEF qualifier.
/DIRECTORY
Displays the names of all the states for which you have defined keys.
If you have not defined keys, the SHOW KEY/DIRECTORY command displays
the DEFAULT and GOLD states (which is the default SYSMAN keypad).
/STATE=(state, state...)
Specifies the name of a state for which the specified key definitions
are to be displayed. If you select more than one state name, separate
them with commas and enclose the list in parentheses.
Description
Specifies the name of the key whose definition you want displayed. See
the DEFINE/KEY command for a list of valid key names.
Example
|
SYSMAN> SHOW KEY/ALL
DEFAULT keypad definitions:
KP0 = "SHOW ENVIRONMENT" (echo)
KP1 = "SHOW PROFILE" (echo)
SYSMAN>
|
This command displays all the key definitions currently in effect.
SHOW PROFILE
Displays the privileges and the default device and directory being used
in the current environment.
Format
SHOW PROFILE
Parameters
None.
Qualifiers
/DEFAULT
Displays the default disk device and directory name that the system
uses in this environment to locate and catalog files.
/PRIVILEGES
Displays only the privileges in effect for the current environment.
Description
The SHOW PROFILE command displays the privileges and the default device
and directory that is being used in the current environment. You can
modify these attributes with the SET PROFILE command.
These values remain in effect until you change environments or enter
another SET PROFILE command.
Example
|
SYSMAN> SHOW PROFILE
%SYSMAN-I-DEFDIR, Default directory on node NODE21 -- WORK1:[BERGERON]
%SYSMAN-I-DEFPRIV, Process privileges on node NODE21 --
TMPMGX
OPER
NETMBX
SYSPRV
|
This command shows the default device and directory as well as current
privileges.
SHOW TIMEOUT
Displays the amount of time SYSMAN waits for a node to respond. By
default, there is no timeout period.
Format
SHOW TIMEOUT
Parameters
None.
Qualifiers
None.
Example
|
SYSMAN> SHOW TIMEOUT
%SYSMAN-I-TIMEVAL, timeout value is 00:00:04.00
|
This command displays the current timeout value, which is 4 seconds.
SHUTDOWN NODE
Shuts down one or more nodes in an OpenVMS Cluster.
The SHUTDOWN NODE command invokes SYS$SYSTEM:SHUTDOWN to shut down one
node or multiple nodes, as you specify, in the current management
environment. You can enter the shutdown command in one command line,
instead of executing the SHUTDOWN.COM procedure on each node
individually.
Requires SETPRV privilege or all of the following privileges: CMKRNL,
EXQUOTA, LOG_IO, OPER, SYSNAM, SYSPRV, TMPMBX, WORLD.
Format
SHUTDOWN NODE
Parameters
None.
Qualifiers
/AUTOMATIC_REBOOT
/NOAUTOMATIC_REBOOT (default)
Reboots the system automatically when the shutdown is complete.
/CLUSTER_SHUTDOWN
/NOCLUSTER_SHUTDOWN (default)
Shuts down the entire cluster.
When you use the /CLUSTER_SHUTDOWN qualifier, each node suspends
activity just short of shutting down completely, until all other nodes
in the cluster have reached the same point in the shutdown procedure.
You must specify this option on every cluster node. If any one node is
not shut down completely, the clusterwide shutdown cannot occur.
You should use the SET ENVIRONMENT/CLUSTER command before you issue a
SHUTDOWN NODE/CLUSTER_SHUTDOWN command to ensure that all nodes in the
cluster are shutting down.
/DISABLE_AUTOSTART
Specifies the number of minutes before shutdown when autostart queues
running on the node are marked stop pending and are subject to failover
to another node.
Using this qualifier gives you control over when the autostart failover
process begins. By default, the value equals that of the
/MINUTES_TO_SHUTDOWN qualifier.
Determine the appropriate number of minutes for your configuration by
weighing a smoother transition against completing a maximum number of
jobs before shutdown. The larger the value, the smoother the transition
will be. The smaller the value, the more jobs will execute on the node.
/INVOKE_SYSHUTDOWN (default)
/NOINVOKE_SYSHUTDOWN
Invokes a site-specific shutdown procedure.
/MINUTES_TO_SHUTDOWN=number
The number of minutes until shutdown occurs. If the system logical name
SHUTDOWN$MINIMUM_MINUTES is defined, its integer value is the minimum
value that you can enter. Therefore, if the logical name is defined as
10, you must specify at least 10 minutes to final shutdown or an error
message displays. If the logical name is not defined, and you do not
enter a value, 0 minutes is the default.
/POWER_OFF
Specifies that the system is to power off after shutdown is complete.
/REASON=text
The reason for the shutdown (one line).
/REBOOT_CHECK
/NOREBOOT_CHECK (default)
Checks for basic operating system files and notifies you if any are
missing. Be sure to replace missing files before rebooting.
/REBOOT_TIME=time
The time when you expect to reboot the system such as IMMEDIATELY, IN
10 MINUTES, 2 P.M., or 14:00:00. Shutdown displays this time in a
shutdown message to users.
/REMOVE_NODE
/NOREMOVE_NODE (default)
Removes a node from the active cluster quorum. Use this qualifier when
you do not expect the shut-down node to rejoin the cluster for an
extended period.
When you use the /REMOVE_NODE qualifier, active quorum in the remainder
of the cluster is adjusted downward to reflect the fact that the
removed node's votes no longer contribute to the quorum value. The
shutdown procedure readjusts the quorum by issuing the SET
CLUSTER/EXPECTED_VOTES command.
You can reset options by using the following command:
SYSMAN> STARTUP SET OPTIONS/NOVERIFY/NOCHECKPOINTING
|
For more information about cluster management, see HP OpenVMS Cluster Systems.
/SAVE_FEEDBACK
/NOSAVE_FEEDBACK (default)
Records feedback data collected from the system since it was last
booted and creates a new version of the AUTOGEN feedback data file,
which you can use the next time you run AUTOGEN.
/SPIN_DOWN_DISKS
/NOSPIN_DOWN_DISKS (default)
Spins down disks. You cannot spin down the system disk.
Description
Because SYSMAN enables you to define the target environment, you can
perform a shutdown on your local node, your own cluster, or a subset of
nodes on your cluster. If you are shutting down a local node, SYSMAN
does not require you to remain logged in to the system during the
shutdown, as long as you set the environment to the local node. See the
SHUTDOWN NODE command examples and the SET ENVIRONMENT command for more
information.
In shutting down the system, the shutdown procedure:
- At decreasing time intervals, broadcasts a message to users to log
out.
- Defines the system logical SHUTDOWN$TIME to reflect the value
entered with the /MINUTES_TO_SHUTDOWN qualifier. For example, if you
entered /MINUTES_TO_SHUTDOWN=10 at 12:00, the shutdown time would be
12:10.
To see if a shutdown is in progress or determine the actual
time for shutdown, use the command SHOW LOGICAL SHUTDOWN$TIME.
- At six minutes or less before shutdown, disables all nonoperator
logins. If DECnet is running, it is shut down.
- At one minute before shutdown, stops batch and device queues and
the system job queue manager.
- At zero minutes before shutdown, invokes the site-specific command
procedure SYS$MANAGER:SHUTDWN.COM.
- Stops all user processes; however, system processes continue.
Ancillary control processes (ACPs) may delete themselves when their
mounted volumes are finally dismounted.
- Stops the secondary processor on dual-processor systems.
- Removes all installed images.
- Dismounts volumes and spins down disks, if you requested it. Does
not spin down the system disk and the quorum disk, if a quorum disk is
present.
- Closes the operator's log file.
- Invokes SYS$SYSTEM:OPCRASH to shut down the system.
- Displays the following message if you did not request an automatic
reboot:
SYSTEM SHUTDOWN COMPLETE - USE CONSOLE TO HALT SYSTEM
|
If you requested an automatic reboot, the system reboots, provided
the necessary controls are set.
Examples
| #1 |
SYSMAN> SET ENVIRONMENT/CLUSTER
SYSMAN> SHUTDOWN NODE/MINUTES_TO_SHUTDOWN=15/REBOOT_TIME="later"-
_SYSMAN> /REASON="SOFTWARE UPGRADE"/REBOOT_CHECK/CLUSTER_SHUTDOWN
|
The first command in this example ensures that all nodes in the cluster
will shut down. The second command requests a shutdown for the entire
cluster and a reboot check for any missing operating system files. The
following messages are displayed to users on the cluster:
SHUTDOWN message on NODE21, from user SYSTEM at NODE21$0PA0: 12:00:00:20
NODE21 will shut down in 15 minutes; back up later. Please log off NODE21.
SOFTWARE UPGRADE
SHUTDOWN message on NODE22, from user SYSTEM at NODE22$0PA0: 12:00:00:22
NODE22 will shut down in 15 minutes; back up later. Please log off NODE22.
SOFTWARE UPGRADE
SHUTDOWN message on NODE23, from user SYSTEM at NODE23$0PA0: 12:00:00:24
NODE23 will shut down in 15 minutes; back up later. Please log off NODE23.
