Rebuilding a Disk Array
When you rebuild a disk array, you are actually rebuilding the data onto a
replacement physical drive.
Rebuilding Automatically
Normally, a Critical disk array automatically rebuilds itself using a designated
spare drive. See “Creating a Spare Drive” on page 99 or page 179.
If you do not have a spare drive, the Critical disk array automatically rebuilds
itself as soon as you remove the failed drive and insert a replacement drive. Note
the replacement drive requirements, below.
Rebuilding Manually
If the Auto Rebuild function is disabled and no spare drives are available, you
must initiate the procedure.
First, identify and replace the failed physical drive. Then rebuild the disk array as
described below:
1. Click the Subsystem icon in Tree View.
2. Click the Disk Arrays icon.
3. Click the Disk Array icon.
If there are multiple disk arrays, choose the icon with the yellow !.
4. From the dropdown menu on the Background Activities tab, choose Start
Rebuild.
5. Choose Source physical drive.
Important
The replacement physical drive must be:
• The same media type, HDD or SDD, as the other drives in the
array.
• Equal or larger capacity than the failed drive it replaces.
• Free of any previous configuration data. See “Clearing Stale
and PFA Conditions” on page 152 or page 269.
