Disks in disk enclosure

CAUTION:
If a data disk fails, the hot spare disk is automatically used until the failed disk is replaced. The
disk is only returned to its status of hot spare disk when the data is fully rebuilt on the replacement
disk. The hot spare disks provide RAID 6 redundancy for the volumes within each drawer. However,
it is important to replace failed or predictive failing disks as soon as possible. If more than two
disks fail in the same pool, the system will fail and data will be lost. See the HP StoreOnce 4900
Backup system Maintenance and Service guide for more detailed information.
Solid blue = The drive is being identified by a host application.
Flashing blue = The drive carrier firmware is being updated or requires an update.

Off = The drive is not configured by a RAID controller.
Solid green = The drive is a member of one or more logical drives.
Flashing green = The drive is rebuilding or performing a RAID migration, stripe size
migration, capacity expansion, or logical drive extension.
Flashing amber/green = The drive is a member of one or more logical drives and predicts
the hard drive will fail.
Flashing amber = The drive is not configured and predicts the hard drive will fail.
Solid amber = The drive has failed.
