Logical Drive Information
A list of logical drives associated with the controller displays in the Mass Storage submenu. Each
logical drive in the list displays the condition, the logical drive number and the fault tolerance of
that logical drive. Select one of the logical drive entries to display the following information.
•
Status displays the status of the logical drive. The logical drive can be in one of the following
states:
◦ OK - The logical drive is in normal operation mode.
◦ Failed - More physical drives have failed than the fault tolerance mode of the logical
drive can handle without data loss.
◦ Unconfigured - The logical drive is not configured.
◦ Interim recovery - The logical drive is using Interim Recovery Mode. In Interim Recovery
Mode, at least one physical drive has failed, but the logical drive's fault tolerance mode
lets the drive continue to operate with no data loss.
◦ Ready for rebuild - The logical drive is ready for Automatic Data Recovery. The physical
drive that failed has been replaced, but the logical drive is still operating in Interim
Recovery Mode.
◦ Rebuilding - The logical drive is currently doing Automatic Data Recovery. During Automatic
Data Recovery, fault tolerance algorithms restore data to the replacement drive.
◦ Wrong drive - The wrong physical drive was replaced after a physical drive failure.
◦ Bad connect - A physical drive is not responding.
◦ Overheating - The drive array enclosure that contains the logical drive is overheating.
The array is still functioning, but should be shut down.
◦ Shutdown - The drive array enclosure that contains the logical drive has overheated. The
logical drive is no longer functioning.
◦ Expanding - The logical drive is currently doing Automatic Data Expansion. During
Automatic Data Expansion, fault tolerance algorithms redistribute logical drive data to
the newly added physical drive.
◦ Not available - The logical drive is currently unavailable. If a logical drive is expanding
and the new configuration frees additional disk space, this free space can be configured
into another logical volume. If this is done, the new volume will be set to Not Available.
◦ Queued for expansion - The logical drive is ready for Automatic Data Expansion. The
logical drive is in the queue for expansion.
When the status is Rebuilding the following will be displayed to indicate the progress of the
operation.
•
Percent Rebuild Complete displays the percent complete of the rebuild. When the value reaches
100, the rebuilding process is complete. The drive array continues to operate in interim
recovery mode while the drive is rebuilding.
•
Rebuilding Drive identifies the physical drive that failed. The logical drive is rebuilding using
a spare drive in place of this failed drive.
When the status is Expanding the following will be displayed to indicate the progress of the
operation.
•
Percent Expand Complete displays the percent complete of the expansion. When a logical
volume is expanding, the drive must redistribute the logical volume data across the physical
drives. When the value reaches 100, the expansion process is complete.
