• Capacity for rollback processing, which is 1/5000th of the capacity of the base virtual disk.
If you are creating a new repository virtual disk when you run this command, you must enter the name of 
a disk group or disk pool from which you want the repository virtual disk. Optionally, you can also define 
the capacity of the repository virtual disk. The following capacity values are supported:
• A percentage ( integer value) representing an amount of the base virtual disk capacity.
• A decimal fraction representing a percentage of the base virtual disk capacity.
• A specific size for the repository virtual disk, in units of bytes, KB, MB, GB, or TB.
To increase capacity for a snapshot virtual disk, use the increaseRepository Capacity and 
capacity parameter as shown below:
set snapVirtualDisk[“snapVirtualDiskName”] increaseRepositoryCapacity 
repositoryVirtualDisks=("repos_xxxx" | repositoryVirtualDisks=(diskGroupName 
[capacity=capacityValue]) repositoryVirtualDisks=(diskPoolName 
[capacity=capacityValue]))
To decrease capacity, replace increaseRepositoryCapacity with decreaseRepository:
set snapVirtualDisk ["snapVirtualDiskName"] decreaseRepositoryCapacity 
count=numberOfVirtualDisks
Setting Snapshot Group Repository Virtual Disk Capacity
To increase or decrease capacity of a snapshot group repository virtual disk, use the same basic 
command syntax as shown previously for the virtual disk repository, except use the set snapGroup 
command and supply the snapshot group name:
set snapGroup ["snapGroupName"] increaseRepositoryCapacity 
(repositoryVirtualDisks="repos_xxxx" | repositoryVirtualDisks=((diskGroupName 
[capacity=capacityValue])) | repositoryVirtualDisks=((diskPoolName 
[capacity=capacityValue])))

Reviving Disk Groups, Physical Disks, Snapshot Groups, And Snapshot Virtual 
Disks
The revive command forces failed physical disks, disk groups, snapshot groups and snapshot virtual 
disks into an Optimal state. However, this command should only be performed by qualified storage 
administrators.
CAUTION: Possible loss of data access—Correct use of this command depends on the data 
configuration on the physical disks in the disk group. Do not attempt to revive a physical disk or 
disk group unless you are explicitly directed by your Technical Support representative.
To revive a physical disk:
revive physicalDisk [enclosureID,drawerID,slotID
For MD-series dense storage arrays, all three location attributes (enclosureIDdrawerID and slotID) are 
required. For non-dense storage arrays, only enclosureID and slotID are required. Valid enclosureID 
values are 0 to 99, drawerID values are 0 to 4 and slotID values are 0 to 31.
To revive disk group:
revive diskGroup [diskGroupName]
To revive a snapshot virtual disk, the snapshot virtual disk must be a:
