HP OpenVMS System Management Utilities Reference Manual

1. The SET ENVIRONMENT command sets the environment for all nodes in the cluster.
2. The output of this DO SHOW QUOTA command shows that disk quotas are enabled over the cluster.
3. The DISKQUOTA DISABLE command disables disk quotas over the entire cluster.
4. The output of this DO SHOW QUOTA command shows that disk quotas have been disabled.

Resumes quota enforcement on a disk volume in the current management environment; this applies to each node that has the disk mounted.

Caution To use the DISKQUOTA ENABLE command on a disk that has been mounted on multiple nodes in a cluster, you must first specify the nodes in the SET ENVIRONMENT command.

Requires SYSPRV privilege, a system UIC, or ownership of the volume.

Format

DISKQUOTA ENABLE

Parameters

None.

Qualifier

/DEVICE=device-spec

Specifies a disk volume on which to enable the quota file. SYSMAN validates the device specification. A logical name may be specified for device-spec. If so, it is translated in the target environment.

Without a device specification, SYSMAN uses the default disk on the target node. Unless you have set a default device with the SET PROFILE command, the default disk is the current device on the local node or the login default device on another node, depending on the established environment.

Description

The DISKQUOTA ENABLE command reinstates the enforcement of quotas on a volume that had been suspended with the DISKQUOTA DISABLE command. Whenever you enable quotas on a volume, use the DISKQUOTA REBUILD command to update UIC entries and usage counts.

Examples

SYSMAN> SET ENVIRONMENT/NODE=(NODE21,NODE22)
SYSMAN> DISKQUOTA ENABLE
SYSMAN> DISKQUOTA REBUILD
      

The DISKQUOTA ENABLE command in this example resumes quota enforcement on the default disk DJA12, which is mounted on NODE21 and NODE22. The DISKQUOTA REBUILD command updates the quota file, correcting quotas and adding any new entries.

SYSMAN> SET ENVIRONMENT/CLUSTER (1)
%SYSMAN-I-ENV, current command environment:
        Clusterwide on local cluster
        Username STEIN    will be used on nonlocal nodes

SYSMAN> DO SHOW QUOTA/DISK=$6$dkd0:/USER=[0,0] (2)
%SYSMAN-I-OUTPUT, command execution on node WALTER
%SYSTEM-F-QFNOTACT, disk quotas not enabled on this volume
%SYSMAN-I-OUTPUT, command execution on node ARTOS2
%SYSTEM-F-QFNOTACT, disk quotas not enabled on this volume
%SYSMAN-I-OUTPUT, command execution on node ARTOS1
%SYSTEM-F-QFNOTACT, disk quotas not enabled on this volume
%SYSMAN-I-OUTPUT, command execution on node EXPERT
%SYSTEM-F-QFNOTACT, disk quotas not enabled on this volume

SYSMAN> DISKQUOTA ENABLE/DEVICE=$6$dkd0: (3)
SYSMAN> DO SHOW QUOTA/DISK=$6$dkd0:/USER=[0,0] (4)
%SYSMAN-I-OUTPUT, command execution on node WALTER
  User [0,0] has 0 blocks used, 1000 available,
  of 1000 authorized and permitted overdraft of 100 blocks on $6$DKD0
%SYSMAN-I-OUTPUT, command execution on node ARTOS2
  User [0,0] has 0 blocks used, 1000 available,
  of 1000 authorized and permitted overdraft of 100 blocks on $6$DKD0
%SYSMAN-I-OUTPUT, command execution on node ARTOS1
  User [0,0] has 0 blocks used, 1000 available,
  of 1000 authorized and permitted overdraft of 100 blocks on $6$DKD0
%SYSMAN-I-OUTPUT, command execution on node EXPERT
  User [0,0] has 0 blocks used, 1000 available,
  of 1000 authorized and permitted overdraft of 100 blocks on $6$DKD0

      

In this example, the disk $6$dkd0: has been mounted clusterwide.

1. The SET ENVIRONMENT command sets the environment for all nodes in the cluster.
2. The output of this DO SHOW QUOTA command shows that disk quotas have not been enabled.
3. The DISKQUOTA ENABLE command enables disk quotas over the entire cluster.
4. The output of this DO SHOW QUOTA command shows that disk quotas have been enabled over the cluster.

Changes an entry in a quota file or adjusts default values for quotas and overdrafts. If a new quota limit is less than the current usage count, SYSMAN issues a warning message before it implements the new quota.

Requires write (W) access to the quota file.

Format

DISKQUOTA MODIFY owner

Parameter

owner

Specifies the user identification code (UIC) or rights identifier. You can specify the UIC in numeric or alphanumeric format. For complete information about UIC specification, refer to the HP OpenVMS Guide to System Security.

Rights identifiers are granted with the Authorize utility and use an ID format rather than a UIC format. Refer to the HP OpenVMS Programming Concepts Manual for a complete description of rights identifiers.

When working in nonlocal environments, make sure that the alphanumeric UIC or rights identifiers that you use are valid for the environment.

Qualifiers

/DEVICE=device-spec

Specifies the disk volume that contains the quota file. SYSMAN validates the device specification. A logical name may be specified for device-spec. If so, it is translated in the target environment.

Without a device specification, SYSMAN uses the default disk on the target node. Unless you have set a default device with the SET PROFILE command, the default disk is the current device on the local node or the login default device on another node, depending on the established environment.

/OVERDRAFT=value

Specifies a positive integer that provides an overdraft value for the specified UIC. If you omit a value, the overdraft value defaults to the overdraft value in the entry for [0,0].

/PERMQUOTA=value

Specifies a positive integer that provides the quota for the specified UIC. If you omit a value, the permanent quota defaults to the value of the quota in the entry for [0,0].

Description

The DISKQUOTA MODIFY command changes values in a quota file for the disk named in the device specification. If you establish a quota limit that is less than the current usage count, a user can still log in and out, but cannot create files.

After creating a quota file, use the DISKQUOTA MODIFY command to set default values for quotas and overdrafts. UIC [0,0] sets the default permanent quota and overdraft values for a quota file, so you must change the entry [0,0] to values appropriate for your installation. Unless you specify quota and overdraft values when adding a file entry, SYSMAN applies these defaults to UIC entries.

Examples

SYSMAN> SET ENVIRONMENT/NODE=NODE21
SYSMAN> DISKQUOTA MODIFY /DEVICE=DUA12: [0,0] -
_SYSMAN> /PERMQUOTA=3000 /OVERDRAFT=300
      

The commands in this example edit the entry for UIC [0,0] in the quota file on DUA12, which is located on NODE21.

SYSMAN> DISKQUOTA MODIFY /DEVICE=SYS$DISK1 [TTD,DAVIS] -
_SYSMAN> /PERMQUOTA=900
      

This command sets the permanent quota for UIC [TTD,DAVIS] to 900 blocks, while making no change to the overdraft limit. SYSMAN modifies the quota file that is located on disk SYS$DISK1 in the current environment.

If the user name DAVIS has a unique UIC on the system, you can enter the following command:

SYSMAN> DISKQUOTA MODIFY DAVIS/PERMQUOTA=900

Updates a quota file, adding new UICs and correcting usage counts for each user on the volume.

Requires write (W) access to the quota file, plus one of the following items: SYSPRV privilege, a system UIC, or ownership of the volume.

Format

DISKQUOTA REBUILD

Parameters

None.

Qualifier

/DEVICE=device-spec

Specifies the disk volume that contains the quota file. SYSMAN validates the device specification and translates any logical name in the target environment before rebuilding the file.

Without a device specification, SYSMAN uses the default disk on the target node. Unless you have set a default device with the SET PROFILE command, the default disk is the current device on the local node or the login default device on another node, depending on the established environment.

Description

The DISKQUOTA REBUILD command reads the disk, recalculates usage counts for all existing entries in QUOTA.SYS, and adds new entries. It sets quota and overdraft values to the defaults set in UIC [0,0] if the entry did not previously exist. While the DISKQUOTA REBUILD command is executing, file activity on the volume is frozen. No files can be created, deleted, extended, or truncated.

Use the DISKQUOTA REBUILD command in the following circumstances:

• After creating a quota file on a volume with existing files.
• When the quota file has been enabled after a period of being disabled. The command corrects the usage counts and adds any new UICs.

Example

SYSMAN> SET ENVIRONMENT /NODE=NODE21
SYSMAN> SET PROFILE /PRIVILEGE=SYSPRV
SYSMAN> DISKQUOTA ENABLE /DEVICE=DUA226:
SYSMAN> DISKQUOTA REBUILD /DEVICE=DUA226:
      

These commands enable the quota file and reconstruct the usage counts for all entries on disk DUA226, which is located on node NODE21.

Removes an entry from a quota file.

Requires write (W) access to the quota file.

Format

DISKQUOTA REMOVE owner

Parameter

owner

Specifies the user identification code (UIC) or rights identifier. You can specify the UIC in numeric or alphanumeric format. For complete information about UIC specification, refer to the HP OpenVMS Guide to System Security.

Rights identifiers are granted with the Authorize utility and use an ID format rather than a UIC format. For more information about rights identifiers, refer to the HP OpenVMS Programming Concepts Manual.

When working in nonlocal environments, be careful that the alphanumeric UIC or rights identifiers that you use are valid for the environment.

Qualifier

/DEVICE=device-spec

Specifies the disk volume containing the quota file. SYSMAN validates the device specification and translates any logical name in the target environment before deleting the UIC entry.

Without a device specification, SYSMAN uses the default disk on the target node. Unless you have set a default device with the SET PROFILE command, the default disk is the current device on the local node or the login default device on another node, depending on the established environment.

Description

The DISKQUOTA REMOVE command eliminates the specified UIC from the quota file on the named device.

If the usage count for the UIC is not zero, files remain on disk and the user can still log in, but any attempt to create or extend files will fail.

The UIC [0,0] entry cannot be removed.

Example

SYSMAN> SET ENVIRONMENT/NODE=MARS
SYSMAN> SHOW PROFILE
%SYSMAN-I-DEFDIR, Default directory on node MARS  -- WORK2:[CASEY]
%SYSMAN-I-DEFPRIV, Process privileges on node MARS --
        TMPMGX
        OPER
        NETMBX
        SYSPRV

SYSMAN> DISKQUOTA REMOVE /DEVICE=DUA45: [TTD,DAVIS]
      

These commands remove UIC [TTD,DAVIS] from the quota file for disk DUA45, which is located on node MARS.

Displays quotas, overdrafts, and usage counts.

Requires no additional privileges to display your own quota, overdraft, and usage count, but otherwise requires read (R) access to the quota file.

Format

DISKQUOTA SHOW owner

Parameter

owner

Specifies the user identification code (UIC) or rights identifier. You can specify the UIC in numeric or alphanumeric format. For complete information about UIC specification, refer to the HP OpenVMS Guide to System Security.

Rights identifiers are granted with the Authorize utility and use an ID format rather than a UIC format. Refer to the HP OpenVMS Programming Concepts Manual for a complete description of rights identifiers.

You can use an asterisk wildcard character (*) to specify the quota entry as follows:

Command	Description
DISQUOTA SHOW CJ	Show user CJ (if CJ has a unique UIC on the system)
DISKQUOTA SHOW [TTD,CJ]	Show user CJ in group TTD
DISKQUOTA SHOW [TTD,*]	Show all users in group TTD
DISKQUOTA SHOW *	Show all entries

Qualifiers

/DEVICE=device-spec

Specifies the disk volume containing the quota file. DISKQUOTA validates device specification and translates any logical name in the target environment before displaying UIC entries.

Without a device specification, SYSMAN uses the default disk on the target node. Unless you have set a default device with the SET PROFILE command, the default disk is the current device on the local node or the login default device on another node, depending on the established environment.

/OUTPUT[=filespec]

Directs output to the specified file. Without a file specification, /OUTPUT defaults to SYSMAN.LIS in the current directory on the local node where you are running SYSMAN.

Example

SYSMAN> DISKQUOTA SHOW [ACCT,*]
      

This command displays quotas, overdrafts, and usage counts for all users in group ACCT on the default disk.

Executes a DCL command or DCL command procedure on all nodes in the current management environment.

Requires the privileges of the DCL command being executed.

Format

DO [command-line]

Parameter

command-line

Specifies a command string that SYSMAN passes to the command line interface (CLI) for execution.

The command DO RUN SYS$SYSTEM:SYSMAN [SYSMAN-command] is not supported. Instead, follow these steps:

1. Enter RUN SYS$SYSTEM:SYSMAN at the dollar ($) prompt.
2. At the SYSMAN> prompt, set the environment to the selected node or nodes with the SET ENVIRONMENT command.
3. Enter a SYSMAN command at the SYSMAN> prompt.

For complete information about DCL command syntax, refer to the HP OpenVMS DCL Dictionary.

Qualifiers

/CONFIRM

Verifies that you want to perform a DO command on each node you have specified with the SYSMAN command SET ENVIRONMENT.

When you use the /CONFIRM qualifier, the system prompts you as follows:

Execute command for node <nodename>? [N]:

The following responses are valid:

YES NO QUIT ALL TRUE FALSE [Ctrl/Z] 1 0 [Ctrl/C] [Return]

Usage Notes

• Affirmative answers are YES, TRUE, and 1.
• Negative answers are NO, FALSE, 0, and pressing the Return key.
• You can use any combination of uppercase and lowercase letters for word responses.
• You can abbreviate word responses to one or more letters (for example, T, TR, or TRU for TRUE), but these abbreviations must be unique.
• Entering QUIT or pressing Ctrl/C or Ctrl/Z indicates that you want to stop processing the command at that point.
• When you enter ALL, the command continues to process, but the system displays no further prompts.
• If you type a response that is not valid, SYSMAN issues an error message and redisplays the prompt.

/OUTPUT[=filespec]

Records output from the command in the specified file, which is located on the node from which you are executing SYSMAN. Position the qualifier immediately after the DO command. The default file specification is SYSMAN.LIS in the current device and directory. SYSMAN prefaces output with the message "%SYSMAN-I-OUTPUT, command execution on node xxxxxx."

/PAUSE

Controls the rate at which the system displays information. Using the /PAUSE qualifier causes the system to display information about one node at a time; the system prompts you to press Return when you are ready to display information about the next node.

Description

The DO command executes the accompanying DCL command or DCL command procedure on all nodes in the current environment. Each DO command executes as an independent process, so no process context is retained between DO commands. For this reason, you must express all DCL commands in a single command string, and you cannot run a program that expects input.

In an OpenVMS Cluster environment, SYSMAN executes the commands sequentially on all nodes in the cluster. Each command executes completely before SYSMAN sends it to the next node in the environment. Any node that is unable to execute the command returns an error message. SYSMAN displays an error message if the timeout period expires before the node responds.

The system cannot display output returned from a command of more than 2048 characters without concatenation.

Three exceptions to be aware of when using the DO command in clusters are the following ones:

• In a multi-architecture heterogeneous cluster running OpenVMS VAX, Alpha, and I64 systems, some uses of the DO command may require special handling. For example, if you are installing images that are named differently in each architecture, you can still use the DO command if you create logical name tables for VAX, Alpha, and I64 nodes. See the example sequence that follows this description for an example.
• Some DCL commands, such as MOUNT/CLUSTER or SET QUORUM/CLUSTER, operate clusterwide by design. It is best to avoid using these kinds of commands with the DO command in SYSMAN when the environment is set to cluster. As alternatives, you could leave SYSMAN temporarily with the SPAWN command and execute these commands in DCL, or you could define the environment to be a single node within the cluster. Similarly, operations on clusterwide logical names and tables operate clusterwide by design.
• Make sure that if you redefine the logical DCLTABLES, you do so in SYLOGICALS.COM, not in SYSTARTUP_VMS.COM or elsewhere. Otherwise, you will receive a command interpreter failure when executing a DO command on a remote node.

Examples

SYSMAN> SET ENVIRONMENT/CLUSTER/NODE=NODE21
SYSMAN> DO/OUTPUT SHOW DEVICE
      

The first command in this example defines the management environment to be the cluster where NODE21 is a member. The second command executes a DCL command on each node in the cluster. Output goes to the file SYSMAN.LIS rather than to the terminal.

SYSMAN> SET ENVIRONMENT/NODE=NODE21
SYSMAN> SET PROFILE /DEFAULT=[CJ.PROGRAMS] -
_SYSMAN> /PRIVILEGES=NOSYSPRV
SYSMAN> DO/OUTPUT @PROCESS_INFO
      

The commands in this example define the environment as a single node and adjust the current privileges and directory. The DO command executes the command procedure PROCESS_INFO.COM, located in directory [CJ.PROGRAMS] and writes any output to SYSMAN.LIS in the directory from which SYSMAN is running.

%SYSMAN-I-OUTPUT, command execution on node NODE24
%SYSMAN-I-OUTPUT, command execution on node NODE25
%SYSMAN-I-OUTPUT, command execution on node NODE26

      

This example shows how you can define logical names for VAX, Alpha, and I64 nodes in a multi-architecture heterogeneous cluster, so that you can use the DO command to install architecture-specific images.

$ RUN SYS$SYSTEM:SYSMAN
SYSMAN> SET ENVIRONMENT/CLUSTER
%SYSMAN-I-ENV, current command environment:
        Clusterwide on local cluster
        Username STEIN   will be used on nonlocal nodes
SYSMAN> DO/CONFIRM SHOW TIME
Execute command for node EXPERT? [N]: Y [Return]
%SYSMAN-I-OUTPUT, command execution on node EXPERT
  22-MAR-2002 09:40:28

Execute command for node MODERN? [N]: Y [Return]

%SYSMAN-I-OUTPUT, command execution on node MODERN
  22-MAR-2002 09:40:56

Execute command for node IMPOSE? [N]: N [Return]

Execute command for node ADU26A? [N]: Y [Return]
   .
   .
   .
      

The commands in this example show how to control whether the system displays time for each node in a cluster.

SYSMAN> DO/PAUSE SHOW TIME
%SYSMAN-I-OUTPUT, command execution on node EXPERT
  22-MAR-2002 09:40:13
Press return to continue [Return]
%SYSMAN-I-OUTPUT, command execution on node MODER
  22-MAR-2002 09:40:41
Press return to continue [Return]
%SYSMAN-I-OUTPUT, command execution on node IMPOSE
  22-MAR-2002 09:39:46
Press return to continue [Return]
   .
   .
