When a Disk Drive Fails
VTrak provides both audible and visual indicators to alert you of a disk drive failure. The following will occur when a disk drive fails or goes offline:
•The Disk Array LED changes from green to amber. See page 262.
•The Disk Carrier Status LED changes from green to red. See page 264.
•The audible alarm repeatedly sounds two short beeps. See page 261.
•WebPAM PROe reports the condition. See page 269.
With a Hot Spare Drive
When a physical drive in a disk array fails and a spare drive of adequate capacity is available, the disk array will begin to rebuild automatically using the spare drive.
After the disk array rebuilds itself using the spare drive, you must replace the failed drive.
To set up a spare drive, see “Create Spare Drive” on page 151 (WebPAM PROe) or “Create New Spare Drive” on page 202 (CLU).
