Hello zuhran,   I'm sorry to see you had a disk fail after firmware updates were applied. I would first mention to make sure you have a backup.     Check LifeCycle logs for disk problems.   To clear the 'phy bad' condition you need to power cycle with no drive in that slot. Unseat the drive in that slot, power cycle, when it is back up reinsert the drive and check condition.   Try a different slot.   I recommend running hardware diagnostics with this guide - [URL]   Please let me know how it goes.  
Hi, We upgraded firmware on one of our Power edge R730 server. Post upgrade, one of the drive was not detected by the controller (H730P Mini) The disk is part of RAID-1 and so the virtual disk is degraded. On OS, can see that the error and I think is related to the backplane. See the snippet from dmesg logs below. *** [ 11.182370] megaraid_sas 0000:02:00.0: 40115 (658263361s/0x0004/CRIT) - Enclosure PD 20(c None/p1) phy bad for slot 21 ***   Would anybody suggest if this is related to the disk or to the backplane? Should we try moving the disk to a different slot?   Thank you.
