Appendix A: Commands | SAS2 Integrated RAID Solution User Guide |
|
| Observe the following rules when creating hot spare disks: |
|
| You cannot create a hot spare disk unless at least one RAID1, RAID10, or RAID1E |
|
| volume already exists. |
|
| You cannot create a hot spare and add it to an inactive Integrated RAID volume. |
|
| For |
|
| the controller use SATA disks. You cannot add a SATA hot spare disk if the existing |
|
| volumes on the controller use SAS disks. |
|
| For |
|
| and you can add a SATA hot spare SSD to a volume with SAS SSDs, if the Integrated |
|
| RAID firmware allows it. This depends on the values in the static fields in |
|
| Manufacturing Page 4. For more information, see the |
|
| Specification Guide. |
|
| The maximum allowable number of hot spare drives depends on the value of the |
|
| MaxGlobalHotSpares field in IOC Page 6. (Normally, the maximum is two global hot |
|
| spares per controller.) |
|
| You cannot add an SSD hot spare to a volume that has HDDs, or vice versa. |
