HP StorageWorks 6000 Virtual Library System - Manual (Page 131)

Powering Off VLS6000 Disk Arrays
CAUTION:
Always power off the node before disconnecting a VHDCI cable or powering off a disk array to
prevent the appliance from erroneously detecting a disk array RAID volume failure.
NOTE:
It is not necessary to power off a disk array when replacing a disk array fan module, power supply,
or hard drive.
To power off a disk array:
1. Power off the node. See “ Powering Off the System ” on page 130.
2. Press the power button on the rear of the disk array.
