-Subject: Retry NOT READY for rdac device handler
-References: bnc#496502
-
-During device discovery read capacity fails with 0x020401 and sets the device
-size to 0. As a reason any I/O submitted to this path gets killed at sd_prep_fn
-with BLKPREP_KILL. This patch is to retry for 0x020401. NEED_RETRY in
-scsi_decide_disposition does not give sufficient time for the device to become
-ready.
