RAID Option ROM User Manual
4
• Status – Shows one of three logical drive conditions:
• Functional – The logical drive is fully operational, and no problems are
present.
• Critical – The logical drive is still operational, meaning you can read
and write data to it. But the logical drive has lost fault tolerance.
For RAID levels 1, 5, and 10, the logical drive contains a failed physical
drive. You must identify and replace the failed physical drive, then
rebuild the logical drive using the RAIDXpert software.
• Offline – The logical drive is no longer operational, meaning you cannot
read and write data to it. You must identify and replace the failed
drive(s). Then you can create a new logical drive and copy your data to
it from the last tape backup or other device.
For RAID levels 1, 5, and 10, two or more physical drives in the logical
drive have failed.
For a RAID 0 or JBOD at least one physical drive has failed.
A RAID Ready logical drive disappears from the user interface when its
physical drive fails.
• Port – The port number to which the Single Disk (unassigned physical drive)
is attached.
• Device Name – The manufacturer’s name and model number of this
physical drive.
