vsdvgts Command
Purpose
Updates the timestamp used by the Recoverable virtual shared disk subsystem by reading the timestamp from the volume group descriptor area (VGDA) of the physical disks.
Syntax
vsdvgts [-a] [ volgrp]
Description
Use this command to update the timestamp that the Recoverable virtual shared disk subsystem uses to determine if a twin-tailed volume group has changed. When the subsystem detects a change, the recovery scripts export the volume group and then import the volume group.
This command can be used to avoid exporting the volume group and then importing the volume group during recovery in situations where the export and import operations are not really necessary. This command should be used very carefully.
Flags
- -a
- Specifies that the timestamps for this volume group for both primary and secondary nodes should be updated. If this flag is not specified, the timestamp is updated on the local node only.
Parameters
- volgrp
- Specifies a volume group. If this operand is not specified, the timestamps for all the volume groups on this node are updated.
Security
You must have root authority to run this command.
Exit Status
- 0
- Indicates the successful completion of the command.
- 1
- Indicates that the program was unable to read one or more timestamps.
Restrictions
You must issue this command from a node that is online in the peer domain. To bring a peer domain online, use the startrpdomain command. To bring a particular node online in an existing peer domain, use the startrpnode command. For more information on creating and administering an RSCT peer domain, refer to the RSCT: Administration Guide.
Standard Output
Current RVSD subsystem run level.
Examples
To update the timestamp associated with the virtual shared disk volume group vsdvg1 for just this node, enter:
