Chapter B Using DC Power 47

Caution – Potential data loss – Moving a 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 expansion trays.

Note – Trays in arrays can be connected to the DC power supply (–48 VDC). Before

turning off any power switches on a DC-powered tray, you must disconnect the two-

pole 20-amp circuit breaker.

Do not move controller trays or 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 array have an Optimal status.

■ Determining the location and status of any global hot spares associated with the

affected storage array.
