Symptoms
When about to perform an OS upgrade to versions OS8.8.62 through OS8.8.64 and if Western Digital 14TB disks drives are in use the disk firmware will be upgraded, the following symptoms will be observed.
Manufacturer | Model | Firmware |
Western Digital | W7214A520ORA014T | A2W0 |
Western Digital | W7214A524ORA014T | C2W0 |
When the firmware on a disk is being upgraded, that specific disk will briefly be taken offline in order for the firmware update to take place. Once the firmware update has completed for that specific disk, it will
then be brought back online, and the process will repeat for the next disk being upgraded. The aforementioned disk models may potentially encounter difficulty in offlining the disk which may in-turn result in
one or more of the following symptoms:
- ZFS Appliance node not able to join the cluster
- The Web-Browser User Interface (BUI) not accessible
- The Command Line Interface (CLI) dropping to emergency mode
- Clients unable to access data
- Commands not returning and/or slow to return
- Disk firmware updates appear to be stuck and not continuing
- etc.
Changes
- Upgrade of Appliance Kit (AK) requiring upgrade of disk drive firmware
- Additional disk drive fault that cause the disk drive to reset
