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 198). Sample scripts are available
from HP StoreVirtual Downloads:

Shutting down a management group also relates to powering off individual storage systems and
maintaining access to volumes. See the HP StoreVirtual LeftHand OS 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).
1. Log in to the management group that you want to shut down.
2. Click Management Group Tasks on the Details tab, and select Shut Down Management Group.
3. Click Shut Down Group.
If volumes are still connected to servers or hosts
After you click Shut Down Group, a confirmation window opens, listing volumes that are still
connected and that will become unavailable if you continue shutting down the management group.
