4. The physical disk are of different types. 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 disk are of different types The physical disk used as a dedicated hot 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. Cannot create a global hot spare If you cannot create a global hot spare, check the following causes: 1. There are no empty physical disks available or the physical disks have not been converted to RAID-capable disks. 2. The physical disk is already part of a virtual disk. 3. The physical disk assigned as the global hot spare has failed. 4. The physical disk assigned as the global hot spare is missing. There are no empty physical disks available or the physical disks have not been converted to RAID-capable disks Install additional physical disks and convert them to a RAID-capable disk, If existing physical disks are Non-RAID they need to be converted to RAID-capable disks. WARNING: When a physical disk is converted to RAID Capable disks, all data on the physical disk is lost. NOTE: A physical disk with a Non-RAID status can be converted to a RAID-Capable disk, if desired, but it is no longer Non-RAID (Converting to RAID-Capable adds PERC S160 configuration information to the physical disk). The physical disk is already part of a virtual disk A dedicated hot spare cannot be assigned to another virtual disk. Troubleshooting your system 47
