Import disk group
The import disk group operation adds the imported disk group to the target storage array. After you complete the import disk group
operation, all of the physical disks have Optimal status. Any associated virtual disks or free capacity nodes are now shown in the MD
Storage Manager installed on the target storage array.
NOTE:
You lose access to your data during the export/import process.
NOTE:
You must export a disk group before you move the disk group or import the disk group.
Importing a disk group
NOTE:
You must insert all of the physical disks that are part of the disk group into the enclosure before the disk group can be
imported.
The following settings are removed/cleared during the procedure:
•
Persistent reservations
•
Host-to-virtual disk mappings
•
Virtual disk copy pairs
•
Snapshot virtual disks and snapshot repository virtual disks
•
Remote replicate pairs
•
Replication repositories
On the target storage array:
1
Insert the exported physical disks into the available physical disk slots.
2
Review the Import Report for an overview of the disk group that you are importing.
3
Check for non-importable components.
4
Confirm that you want to proceed with the import procedure.
NOTE:
Some settings cannot be imported during the import disk group procedure.
Non-importable components
Some components cannot be imported during the import disk group procedure. These components are removed during the procedure:
•
Persistent reservations
•
Mappings
•
Virtual disk copy pairs
•
Snapshot virtual disks and snapshot repository virtual disks
Storage array media scan
The media scan is a background operation that examines virtual disks to verify that data is accessible. The process finds media errors
before normal read and write activity is disrupted and reports errors to the event log.
NOTE:
You cannot enable background media scans on a virtual disk comprised of Solid State Disks (SSDs).
Errors discovered by the media scan include:
•
Unrecovered media error — Data could not be read on the first attempt or on any subsequent attempts. For virtual disks with
consistency protection, data is reconstructed, rewritten to the physical disk, and verified and the error is reported to the event log. For
