Server Administrator Storage Management 8.2 User’s Guide

The following considerations apply to dedicated hot spares:

• Considerations for RAID 10, RAID 50, and RAID 60 — If you have created a RAID 10 or RAID 50 virtual disk that does not fully consume its member physical disks, then you cannot assign a dedicated hot spare to the RAID 10 or RAID 50 virtual disk. Storage Management does not allow you to create RAID 10 and RAID 50 virtual disks from partial physical disks. You therefore do not encounter this situation if you use Storage Management to create your virtual disks. If, however, the RAID 10 or 50 virtual disk was created using another application and if it does contain partial physical disks, then you can assign a dedicated hot spare to the virtual disk.
  • NOTE: For PERC H700 and PERC H800 controllers, you can assign a dedicated hot spare to RAID 10, RAID 50, and RAID 60.
• Considerations for Multiple Dedicated Hot Spares — From Storage Management version 3.1 onwards, you can assign more than one dedicated hot spare to a virtual disk.
  • NOTE: This feature is applicable only on PERC 6 family of controllers.
