rvsdrestrict Command

Purpose

rvsdrestrict – Displays and sets the run level of the Recoverable virtual shared disk subsystem. This command must be issued before the RVSD subsystem will start.

Syntax

rvsdrestrict
{-l | -s {RVSD4.1 | RESET}}

Description

The rvsdrestrict command is used to restrict the level at which the Recoverable virtual shared disk subsystem will run. If a node has a lower level of the RVSD software installed than what is set with this command, then the RVSD subsystem will not start on that node.

This command does not dynamically change RVSD subsystem run levels across the peer domain. An RVSD subsystem instance will only react to this information after being restarted. If your peer domain runs at a given level, and you want to override this level, you must:
  1. Stop the RVSD subsystem on all nodes.
  2. Override the level.
  3. Restart the RVSD subsystem.

Flags

-l
Lists the current RVSD subsystem run level.
-s
Sets the RVSD subsystem run level.

Parameters

None.

Security

You must have root authority to run this command.

Exit Status

0
Indicates the successful completion of the command.
nonzero
Indicates that an error occurred.

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

  1. To set the RVSD subsystem run level to RVSD4.1, you would issue the command: 
    rvsdrestrict -s RVSD4.1
