Shutting down a management group
Safely shut down a management group to ensure the safety of your data. Shutting down lets you:
•
Perform maintenance on storage systems in that group
•
Move storage systems around in your data center
•
Perform maintenance on other equipment such as switches or UPS units
•
Prepare for a pending natural disaster
HP also recommends creating a script to configure a safe shut down in the case of a controlled
power down by a UPS. See
“Working with scripting” (page 196)
. Sample scripts are available
from HP LeftHand Software Downloads:
http://www.hp.com/go/lefthanddownloads
Shutting down a management group also relates to powering off individual storage systems and
maintaining access to volumes. See the HP LeftHand Storage Command Line Interface User Guide,
for more information.
Prerequisites
•
Disconnect any hosts or servers that are accessing volumes in the management group.
•
Wait for any restriping of volumes or snapshots to complete.
•
Stop managers on storage systems that you plan to remove from the management group. You
may want to add a FOM or start a Virtual Manager on a different storage system to maintain
quorum and the best fault tolerance. See
“Stopping managers” (page 113)
.
