Dell PowerVault MD3820f - Manual (Page 169)

• Snapshot group
• Snapshot virtual disk
• Consistency group member virtual disk
• Consistency group member snapshot virtual disk
• Replicated pair
Use this option when you receive a warning that the overall repository is in danger of becoming full. You
can increase the repository capacity by performing one of these tasks:
• Adding one or more existing repository virtual disks.
• Creating a new repository virtual disk using free capacity that is available on a disk group or disk pool.
NOTE: If no free capacity exists on any disk group or disk pool, you can add unconfigured
capacity in the form of unused physical disks to a disk group or disk pool.
You cannot increase the storage capacity of an overall repository if one of these conditions exists:
• The repository virtual disk that you want to add does not have an Optimal status.
• Any repository virtual disk in the disk group or disk pool that you want to add is in any state of
modification.
• No free capacity exists in the disk group or disk pool that you want to add.
• No unconfigured capacity exists in the disk group or disk pool that you want to add.
• There are no eligible existing repository virtual disks (including mismatched DS attributes).
• Make sure that a base virtual disk and each of the individual repository virtual disks in the overall
repository have the same Data Service (DS) attributes, specifically for the following characteristics:
• RAID Level — A repository in a disk pool is considered to have a matching RAID Level for any base
virtual disk on a disk group, regardless of the base virtual disk’s actual RAID Level. However, a
repository on a disk group is considered to have a matching RAID Level only if that RAID Level is
identical to the RAID Level of the base virtual disk.
• Physical Disk Type — A match requires that the base virtual disk and the repository virtual disk reside
on either a disk group or disk pool with identical physical disk type attributes.
• You cannot increase or decrease the repository capacity for a snapshot virtual disk that is read-only
because it does not have an associated repository. Only snapshot virtual disks that are read-write
require a repository.
To increase the overall repository capacity:
1. From the AMW, select the Storage & Copy Services tab.
2. Select the storage object for which you want to increase the repository capacity.
3. Right click the selected storage object and select Overall Repository → Increase Capacity.
The Increase Repository Capacity window is displayed.
4. To increase capacity of the overall repository, do one of the following:
– Select Add one or more existing repository virtual disks and then go to step 4.
– Select Create and add new repository virtual disk and then go to step 5.
