Relocation Cautions
Use the following guidelines when relocating trays or drives from one storage array
to another.
Caution – Potential data loss – Moving a storage array or array components that are
configured as part of a volume group can result in data loss. To prevent data loss,
always consult a Customer Support representative before relocating configured
drives, controller trays, or drive expansion trays.
Do not move controller trays or drive expansion trays that are part of a volume
group configuration. If you must move array components, contact a Customer
Support representative for procedures. A Customer Support representative might
direct you to complete several tasks prior to undertaking the relocation. These tasks
might include:
■ Creating, saving, and printing an array profile of each storage array that is
affected by the relocation of a drive or tray.
■ Performing a complete backup of all data on the drives that you intend to move.
■ Verifying that the volume group and each of its associated volumes on the
affected storage array have an Optimal status.
■ Determining the location and status of any global hot spares associated with the
affected storage array.
