Set or change local bandwidth priority
1. In the navigation window, select a management group and log in.
2. Click Management Group Tasks on the Details tab, and select Edit Management Group.
3. Change the local bandwidth priority using the slider.
A default setting of 4, at the Application Access end of the slider, is more appropriate for
everyday situations where many servers are busy with the volume. A setting of 40, at the Data
Rebuild end of the slider, is most commonly used for quick data migration or copies when
rebuilding or moving damaged volumes.
4. Click OK.
The new rate appears on the Details tab in the management group tab window.
Saving management group configuration information
Use View Management Group Configuration to save the configuration description. This creates a
.txt file that lists the details of the management group configuration.
1. From the Tasks menu, select Management Group
→View Management Group Configuration.
2. Select the management group if necessary.
3. Click Save in the Management Group Configuration window to save the configuration details
in a .txt. file.
Safely 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
Also, use 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 the Customer Resource
Center.
Shutting down a management group also relates to powering off individual storage systems and
maintaining access to volumes. See the command line documentation, the HP P4000 SAN/iQ
Command Line Interface User Guide, installed in the documentation directory of the program files.
