If a disk drive rebuild fails because of a source drive failure or because the
drive is too small, the MDSM reports a failure of the physical disk even
though the LED state on the drive indicates the rebuild was aborted (green
for 3 seconds, amber for 3 seconds, then off for 3 seconds).

Self-Monitoring Analysis and Reporting Technology

SMART monitors the internal performance of all physical disk components to
detect faults indicating the potential for physical disk failure. SMART uses
this information to report whether failure is imminent so that a physical disk
can be replaced before failure occurs. The storage array monitors all attached
drives and notifies you when a predicted failure is reported by a physical disk.

Virtual Disks and Disk Groups

1 Organize the physical disks into disk groups.
2 Create virtual disks within these disk groups.
3 Provide host server access.
4 Create mappings to associate the virtual disks with the host servers.
NOTE:
Host server access must be created before mapping virtual disks.
