Dedicated Hot spare

[stranger12345678]

Is dedicated hot spare unsupported in iDRAC 9 ? Global hot spare works fine. Don't see an option to set a disk as dedicated spare in iDRAC UI. So just gave a try to do the same using redfish API, and that too failed.

Hi @stranger12345678

Yes assign DHS is supported on iDRAC 9. The disk must be either the same size or larger size compared to the disks used in the RAID volume.

In the IDRAC GUI, under Configuration/Storage Configuration / Virtual Disk / Virtual Disk Actions you should see an option to assign DHS in the drop down menu if a supported disk(s) is available to assign as DHS.

Example:

Example using Redfish to assign DHS.

C:\Python39>AssignHotSpareREDFISH.py -ip 192.168.0.120 -u root -p calvin -v RAID.Integrated.1-1

- Volume(s) detected for RAID.Integrated.1-1 controller -

Disk.Virtual.0:RAID.Integrated.1-1, Volume type: Mirrored

C:\Python39>AssignHotSpareREDFISH.py -ip 192.168.0.120 -u root -p calvin -d RAID.Integrated.1-1

- Drive(s) detected for RAID.Integrated.1-1 -

Disk.Bay.0:Enclosure.Internal.0-1:RAID.Integrated.1-1
Disk.Bay.1:Enclosure.Internal.0-1:RAID.Integrated.1-1
Disk.Bay.2:Enclosure.Internal.0-1:RAID.Integrated.1-1
Disk.Bay.3:Enclosure.Internal.0-1:RAID.Integrated.1-1

C:\Python39>AssignHotSpareREDFISH.py -ip 192.168.0.120 -u root -p calvin -H RAID.Integrated.1-1

okay thanks, it works for RAID 1. I was trying for RAID 0.

Correct, assign DHS is only supported for a RAID volume which supports mirroring. Thanks for confirming it works.
