9.5.01 HP P4000 SAN Solution User Guide (AX696-96168, February 2012)

NOTE: The system automatically factors data protection levels into the settings. For example, if
you create a fully provisioned 500 GB volume and the data protection level is Network RAID-10
(2–Way Mirror), the system automatically allocates 1000 GB for the volume.
To set advanced characteristics for a volume, continue on the Advanced tab of the New Volume
window.
Configuring advanced volume settings [optional]
Set additional characteristics for a volume in the Advanced tab in the New Volume window.
Advanced settings include the following:
• Cluster (changing the cluster is typically used to migrate volumes to a different cluster at some
later time)
• Data protection level
• Volume type
• Provisioning
Descriptions of these characteristics are found in “Characteristics for new volumes” (page 156).
Configuring advanced volume settings
Configure the Advanced settings when you create the new volume if you do not want to use the
default settings.
1. Click the Advanced tab on the New Volume window.
2. Change the desired characteristics and click OK when you are finished.
Configuring a volume for either Network RAID-5 or Network RAID-6 automatically creates a
snapshot schedule. This default schedule is named VolumeName_Schedule, recurs once daily, and
retains 1 copy. The first snapshot is created one day after the schedule is created. You can edit
this schedule as desired, as described in “Editing scheduled snapshots” (page 168).
Volumes map view
After you create volumes and finish setting up the SAN, use the Map View tab for viewing the
relationships between volumes, snapshots, servers, and remote copies. For more information on
using the map view tools, see “Using the display tools” (page 14).
Volumes map views include the following:
• Volume Hierarchy
• Remote Copies
• Remote Copies (Volume Hierarchies)
• Servers to Volumes
Editing a volume
When editing a primary volume, you can change the description, size, and advanced characteristics
such as the cluster, data protection level, type and provisioning.
NOTE: Moving the volume to a different cluster requires restriping the data in both clusters.
Restriping can take hours, or even days.
