preparevsd Command

Purpose

Makes a virtual shared disk available.

Syntax

preparevsd {-a | vsd_name…}

Description

The preparevsd command brings the specified virtual shared disks from the stopped state to the suspended state. The virtual shared disks are made available. Open and close requests are honored, while read and write requests are held until the virtual shared disks are brought to the active state. If they are in the suspended state, this command leaves them in the suspended state.

You can use the System Management Interface Tool (SMIT) to run this command. To use SMIT, enter:

smit vsd_mgmt

And select the Prepare a Virtual Shared Disk option.

Under normal circumstances, you must not issue this command. The recoverable virtual shared disk subsystem uses this command to manage shared disks in a controlled manner. If you issue this command, the results are unpredictable.

Flags

Parameters

vsd_name

Specifies a virtual shared disk. If the virtual shared disk is not in the stopped state, you get an error message.
