6. After replacing a failed drive, save the configuration settings as described in
“Saving Configuration Settings” on page 82.
The saved configuration includes configuration information for all the drive
modules in the virtual disk. When you save the configuration settings to a file, you
also save the configuration of the virtual disk onto each of the hard drives. This step
saves the current configuration onto the new hard drive. If the drive is used as a
spare, its metadata is automatically updatd.
Verify That the Correct Power-On Sequence Was
Performed
Review the power-on sequence that you most recently used for the enclosure. If you
are uncertain about the sequence used, repeat the power-on sequence in the
following order to see if it results in a Good status for the virtual disk that originally
had the failed drive.
1. Power up the enclosures and associated data host in the following order:
a. Drive enclosures first
b. Controller enclosure next
Quarantined
The vdisk is offline and has been quarantined
because some drives are missing.
Wait for the missing drive to come online. If it
doesn’t, create another vdisk and perform a restore
from the latest backed up copy.
Select Manage > Virtual Disk Config > Create A
Vdisk. To restore a configuration file, select
Manage > Utilities > Configuration Utilities >
Restore Config File.
Leftover
All of the member disk drives in a virtual disk
contain metadata in the first sectors. The storage
system uses the metadata to identify virtual disk
members after restarting or replacing enclosures.
Clear the metadata if you have a disk drive that was
previously a member of a virtual disk. After you
clear the metadata, you can use the disk drive in a
virtual disk or as a spare:
Select Manage > Utilities > Disk Drive Utilities >
Clear Metadata.
Select the disk, and click on Clear Metadata for
Selected Disk Drives.
