Migrating a virtual disk
Migrate a virtual disk to a new disk group and/or change the Vraid level of a virtual disk. Both
operations can be performed simultaneously.
Considerations
• You can use the GUI, jobs, or the CLUI to migrate a virtual disk. See Virtual disks actions cross
reference.
• Only virtual disks that do not have local or remote replicas can be migrated.
• Only fully allocated virtual disks can be migrated. Virtual disks using thin provisioning cannot
be migrated.
• While a migration is in progress, other operations cannot be performed on the virtual disk.
This includes presenting or unpresenting the virtual disk and creating local replicas.
• When migrating a virtual disk, the write cache policy is set to write-back as part of the migrate
process. If the virtual disk had write cache policy set to write-through, the policy will be changed
to write-back.
