Table 7-11. Cannot Assign a Dedicated Hot Spare to a Virtual Disk
Likely Causes to Check Corrective Actions
The RAID level does not allow a
dedicated hot spare to be created
Hot spares cannot be created for Volume or RAID 0
virtual disks.
The designated physical disk
does not have sufficient capacity
to be a dedicated hot spare
The capacity of the physical disk selected to be a
dedicated hot spare must be equal to or larger than
the capacity of the smallest physical disk in the
virtual disk.
For example, if the physical disk selected for a
dedicated hot spare is 160 GB, and the physical
disks in the virtual disk are 80 GB, 160 GB, and
500 GB, a dedicated hot spare can be assigned.
That is because the physical disk selected for the
dedicated hot spare is larger than the smallest
(80 GB) physical disk in the virtual disk.
The physical disk is already part
of a virtual disk
A dedicated hot spare cannot be assigned to
another virtual disk.
The physical disks are of
different types
The physical disk used as a dedicated spare must be
the same type as the physical disks that are already
part of the virtual disk. For example, if a virtual disk
consists of SATA-II physical disks, the dedicated
hot spare must be a SATA-II physical disk.
Table 7-12. Cannot Create a Global Hot Spare
Likely Causes to Check Corrective Actions
There are no empty physical
disks available or the physical
disks have not been initialized
Install additional physical disks and initialize them.
If existing physical disks have a status of New they
need to be initialized.
WARNING: When a physical disk is initialized, all
data on the physical disk is lost.
NOTE: A physical disk with a Non-Raid status can be
initialized, if desired, but it is no longer Non-Raid
(initialization adds PERC S100 adapter/PERC S300
adapter configuration information to the physical
disk).
