I have a Dell PowerEdge 2950 II with BIOS version 2.7.0. In it I have three 300 GB Intel 320 SSD disks. They are in a RAID 5 configuration. The problem is that when I add a fourth disk, whether it is another SSD of the same model, a non-SSD SATA disk, or a non-SSD SAS disk, OpenManage does not allow me to assign the fourth disk as a hot spare for the raid array. If I attempt to assign the fourth disk as a global hot spare, OpenManage warns me that the disk won't be eligible to be used as a hot spare for any of the existing arrays. Another interesting thing is that the light on the hot swap bay that normally is solid green doesn't turn on at all for these SSDs. Only the disk activity light does anything, namely blinking.
I am wondering what I can do to get a hot spare working with this raid array.
The perc 5 firmware is version 5.2.2-0072. OpenManage is version 6.5.0. The server is running Windows Server 2008 Standard R2 64-bit.
Thanks for any help!
