stopvsd Command

Purpose

stopvsd – Makes a virtual shared disk unavailable.

Syntax

stopvsd {-a | vsd_name …}

Description

The stopvsd command brings the specified virtual shared disks from the suspended state to the stopped state. This makes the virtual shared disks unavailable. All applications that have outstanding requests for the virtual shared disk see these requests terminate with error. Read and write requests return errors with errno set to ENODEV. If the virtual shared disk is in the stopped state, this command leaves it in the stopped state.

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

smit vsd_mgmt
