PowerEdge 2950 PERC 5/i VD not rebuilding after failed disk

Have 2 VDs defined:  0: raid-1 (boot disk), 1: raid-10 (data disk)

Noticed failed disk (0:0:2) and degraded VD 1. Removed (live) and inserted new disk. VD (1) not rebuilding.  No hot spares configured.

in OMSA (5.5.0)

- attempt to rebuild disk reports

 # omconfig storage pdisk action=rebuild controller=0 pdisk=0:0:2
Operation disabled. Read, action=rebuild
.Refer to the documentation for more information.

In RAID BIOS (5.2.2-0072)

- disk shows as ready in the PD management

- disk shows as missing in the VD management

- only options on pd management for disk is blink led or assign as global host spare. Latter completes but warns that the disk will not be available for either VD

See postings from users having success w/ "VD reconfigure" action, but they are not using the CLI and don't give specifics of command parameters. SO - is reconfigure of the VD the way to go here? Or is that strictly to change size or expand. What are my options?

Prefer to use the OMSA interface as this is a critical system and would like to have rebuild occur in background.

RE: PowerEdge 2950 PERC 5/i VD not rebuilding after failed disk

Hi,

Do not reconfigure the VD, that is for expanding an array. Assigning it as a hot spare is the right option, but if it says it isn’t going to work, usually it means that the replacement drive is not large enough. What size is the drive showing?

Thanks,

replacement disk (new) is larger. I have same size/manufacturer disks, but they were used. Thought best to try w/ a new one first. See 0:0:2 below.

RE: PowerEdge 2950 PERC 5/i VD not rebuilding after failed disk

 Type : SAS

Type : SATA

That is the problem, it is a SATA drive and the other drives are SAS. SAS and SATA are not able to mix in the same array.

RE: PowerEdge 2950 PERC 5/i VD not rebuilding after failed disk

oh duh. so, should I try w/ a disk that I formerly used? Note - I have several that I "wiped' (initialized) within the context of a new VD on a different machine, then I deleted the VD. Am presuming if I used it, it would come up foreign, which I would then clear. But may have to query again if something goes not to plan.

It should work, as long as it is SAS. If it does show foreign, clear the foreign and set it as a hotspare.

RE: PowerEdge 2950 PERC 5/i VD not rebuilding after failed disk

thanks - that worked. The new (used) disk is rebuilding. It did not come up as foreign, since presumably having deleted the VD info when the spare was on different system must have cleared any "foreign" vd info.
