Using Your RAID Enclosure 41
Use either of the following methods to move disk groups and virtual disks:
• Hot virtual disk migration — Disk migration with the destination storage
array power turned on.
• Cold virtual disk migration — Disk migration with the destination storage
array power turned off.
NOTE: To ensure that the migrating disk groups and virtual disks are correctly
recognized when the target storage array has an existing physical disk, use hot
virtual disk migration.
When attempting virtual disk migration, follow these recommendations:
• Moving physical disks to the destination array for migration — When
inserting drives into the destination storage array during hot virtual disk
migration, wait for the inserted physical disk to be displayed in the MD
Storage Manager before inserting the next physical disk.
NOTICE: Without the delay between drive insertions, the storage array can
become unstable and manageability is temporarily lost.
• Migrating virtual disks from multiple storage arrays into a single storage
array — When migrating virtual disks from multiple, different storage
arrays into a single destination storage array, move all of the physical disks
from the same storage array as a set into the new destination storage array.
Ensure that all of the physical disks from a storage array are migrated to
the destination storage array before starting migration from the next
storage array.
NOTE: If the drive modules are not moved as a set to the destination storage array,
the newly relocated disk groups might not be accessible.
• Migrating virtual disks to a storage array with no existing physical disks —
When migrating disk groups or a complete set of physical disks from a
storage array to another storage array that has no existing physical disks,
turn off the destination storage array. After the destination storage array
has been turned on and has successfully recognized the newly migrated
physical disks, migration operations can continue.
NOTE: Disk groups from multiple storage arrays should not be migrated at the same
time to a storage array that has no existing physical disks. Use cold virtual disk
migration for the disk groups from one storage array.
