PowerFlex storcli add vd command complains "hard drive does not have appropriate attributes"
Summary: Storcli add vd command complains "hard drive does not have appropriate attributes"
Symptoms
Scenario
This can happen when a disk is pulled from the enclosure and put back in, without following the correct procedure.
This can happen on VxRack Node and other systems using LSI controller and storcli.
Symptoms
The error on storcli adds the vd command:
# /opt/MegaRAID/storcli/storcli64 /c0 add vd type=raid0 drives=252:2 direct wb ra Controller = 0 Status = Failure Description = physical disk does not have appropriate attributes
In the "storcli /c0 show" output, 252:2's state is "UBad" and DG is "F":
# /opt/MegaRAID/storcli/storcli64 /c0 show ...

Impact
Unable to use the disk.
Cause
When a disk is pulled and put back in, the controller might consider this disk's configuration "foreign" (DG=F). This prevents the controller from using the disk, and attempts to add VD on this PD will fail.
Resolution
The foreign configuration must be deleted before the controller can use the PD.
Note: this operation invalidates data on the disk. This should not cause issues for ScaleIO as there will be two copies for all data.
1. Clear the "Ubad" state of the PD if any:
# /opt/MegaRAID/storcli/storcli64 /c0/e252/s2 set good Controller = 0 Status = Success Description = Set Drive Good Succeeded.
2. Verify the foreign configuration with "storcli /c0/fall show"
# /opt/MegaRAID/storcli/storcli64 /c0/fall show Controller = 0 Status = Success Description = Operation on foreign configuration Succeeded FOREIGN CONFIGURATION : ===================== ----------------------------------------- DG EID:Slot Type State Size NoVDs ----------------------------------------- 0 - RAID0 Frgn 837.843 GB 1 ----------------------------------------- NoVDs - Number of VDs in disk group|DG - Diskgroup Total foreign drive groups = 1
3. Delete the foreign configuration with "storcli /c0/fall del"
# /opt/MegaRAID/storcli/storcli64 /c0/fall del Controller = 0 Status = Success Description = Successfully deleted foreign configuration
After that "storcli /c0 show" will show the PD in the UGood state with a valid DG number, and the PD can be used for the "add vd" command again.
