Cause

When iDRAC9 is running low on memory while updating the staged BIOS job, iDRAC SMA daemon is restarted while trying to process the BIOS file transfer.

Resolution

iDRAC9 firmware version 6.00.30.00 corrects the memory handling to prevent this staged BIOS update failure condition.

Workaround:
Clear and delete current iDRAC jobs and reset iDRAC.

#racadm jobqueue delete -i JID_CLEARALL_FORCE  (this is the only way to delete a job in running state).

racadm>>racadm jobqueue delete -i JID_CLEARALL_FORCE
RAC1032: JID_CLEARALL_FORCE job(s) was cancelled by the user.

#racadm racreset

racadm>>racadm racreset
RAC reset operation initiated successfully. It may take a few minutes for the RAC to come online again.
