Hot Spare Failover
If a RAID 1 or RAID 10 virtual disk enters a degraded state, a compatible hot
spare automatically begins rebuilding the degraded virtual disk. The "missing"
or "failed" member of the degraded virtual disk is displayed as a ‘missing’
global hot spare. The "missing" or "failed" drive must be replaced with a drive
compatible with an existing virtual disk(s).
NOTE: A compatible drive is one that is of the same drive type (SAS, SATA, or SSD)
and of equal or greater size of the disk being replaced.
Replacing and Rebuilding a Degraded Virtual Disk
In the event of a physical disk failure in a RAID 1 or RAID 10 virtual disk,
you will need to replace the disk and resynchronize the virtual disk.
Synchronization occurs automatically on replacing the physical disk using the
following steps.
1
Replace the failed physical disk with a blank disk of the same type and of
equal or greater capacity.
2
Check your management application or the
BIOS Configuration Utility
(<Ctrl><C>) to ensure synchronization started automatically.
NOTE: During the rebuilding of a volume the synchronization will be restarted
from the beginning if a hard drive is added or removed from the system. Wait until
any synchronization processes have been completed before adding or
removing hard drives.
NOTE: Always remove any configuration information from hard drives if they are to
be permanently removed from a system. This can be completed by deleting the
RAID configuration through the BIOS Configuration Utility or an operating system
unless you are migrating these hard drives to a different system level application.
PERC H200 hotspare functionality requires that the slots in which hard drives are
inserted be associated with the virtual disks they are a part of. Do not insert hard
drives with foreign or old (out of date) configuration information stored on those
hard drives into slots that are associated with existing virtual disks.
NOTE: If the system is rebooted while the rebuild is in progress, the rebuild
continues from where it left off as a result of rebuild checkpointing. The rebuild time
for a volume varies depending on the size of the member disks and any additional
system activity.
