Disk Array Operational Status
• OK – The normal state of a disk array. For RAID Levels other than RAID 0
(Striping), the disk array has full redundancy.
• Synchronizing – When you first create a disk array, the disk array
synchronizes. During that time, your data is available. However, access will
be slower until synchronizing is done.
• Critical/Degraded – This condition results from a physical drive failure. Your
data is still available. However, the disk array has lost redundancy (fault
tolerance). You must determine the cause of the problem and correct it. See
“Critical & Offline Disk Arrays” on page 290.
• Rebuilding – This condition is temporary. When a physical drive has been
replaced, the disk array automatically begins rebuilding in order to restore
redundancy (fault tolerance). Your data is still available. However, access will
be slower until rebuilding is done.
• Transport Ready – The result of a successful Prepare for Transport
operation. You remove the physical drives of this disk array and move them
to another enclosure or to different drive slots in the same enclosure. After
you relocate the physical drives, the disk array status will show OK.
Adjustable Items
• Alias – Optional.
• Media Patrol – Enabled or disabled.
• PDM – Enabled or disabled.
