Status Mode Description
Optimal Hot Spare in use The physical disk in the indicated slot is in use as a hot
spare within a disk group.
Failed Assigned, Unassigned, Hot Spare
in use, or Hot Spare Standby The physical disk in the indicated slot has failed because
of an unrecoverable error, an incorrect drive type or
drive size, or by its operational state being set to failed.
Replaced Assigned The physical disk in the indicated slot has been replaced
and is ready to be, or is actively being, configured into a
disk group.
Pending Failure Assigned, Unassigned, Hot Spare
in use, or Hot Spare Standby A Self-Monitoring Analysis and Reporting Technology
(SMART) error has been detected on the physical disk in
the indicated slot.
Offline Not applicable The physical disk has either been spun down or had a
rebuild aborted by user request.
Identify Assigned, Unassigned, Hot Spare
in use, or Hot Spare Standby The physical disk is being identified.
Self-Monitoring Analysis And Reporting Technology
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
When configuring a storage array, you must:
• Organize the physical disks into disk groups.
• Create virtual disks within these disk groups.
• Provide host server access.
• Create mappings to associate the virtual disks with the host servers.
NOTE: Host server access must be created before mapping virtual disks.
Disk groups are always created in the unconfigured capacity of a storage array. Unconfigured capacity is the available
physical disk space not already assigned in the storage array.
Virtual disks are created within the free capacity of a disk group. Free capacity is the space in a disk group that has not
been assigned to a virtual disk.
Virtual Disk States
The following table describes the various states of the virtual disk, recognized by the storage array.
