Take Physical Disk Offline using iDRAC/racadm
I have a T320 with iDRAC Enterprise and a RAID-1 array on a PERC H310. I would like to replace one of the array's physical disks preemptively (not in failed state, or predictive failed state) and need to have the controller take it offline before I remove it. I cannot find in the iDRAC UI, or the iDRAC or racadm documentation how to do this. I would prefer to not need to use OMSA. Any way to do it? Thanks for any help.
Hello
Type this RACADM command and it should provide information on the syntax:
racadm raid help forceoffline
SpoilerC:\Users\Administrator>racadm raid help forceoffline
Storage -- forceoffline command removes the drive from Virtual Disk configuration
Usage:
racadm storage forceonline:
--------------------------------------------------------------------------------
Valid Options:
NA
--------------------------------------------------------------------------------
Usage Examples:
racadm storage forceoffline:Disk.Bay.0:Enclosure.Internal.0-0:RAID.Integrated.1-1
C:\Users\Administrator>racadm raid help forceoffline Storage -- forceoffline command removes the drive from Virtual Disk configuration Usage: racadm storage forceonline: -------------------------------------------------------------------------------- Valid Options: NA -------------------------------------------------------------------------------- Usage Examples: racadm storage forceoffline:Disk.Bay.0:Enclosure.Internal.0-0:RAID.Integrated.1-1There is a RACADM CLI guide on the iDRAC support page. OMSA has OMCONFIG commands that can offline a physical disk as well. The OMSA CLI guide is on the OMSA support page.

I am running 2.50.50.50 and there is no "forceoffline" under "storage". There is a "preparetoremove" but the documentation implies that it is for PCIeSSD drives. What is the proper command to force a rotational SAS drive offline in this iDRAC release?

I ended up updating the iDRAC firmware to get the new "forceoffline" command. Still in disbelief, with how much money I paid for this Gen-12 server, that I have to reboot to take a hot-swap drive offline in preparation for replacement!
