This is indicating there is an issue with sdg
Some additional troubleshooting
Attempt to prepare the storage from the command line.
# mdadm --detail /dev/md99

# mdadm --examine /dev/md99
mdadm: No md superblock detected on /dev/md99. (This is bad)
# mkfs.xfs -f /dev/md99
Error:
mkfs.xfs: pwrite64 failed: Input/output error (This is also bad)
Next you can attempt to write a filesystem to the other device to verify if they need to be replaced.
First stop md99
# mdadm --stop /dev/md99
Next try to write a filesystem to each device
(CAUTION: Incorrect naming of /dev/sdx can direct to a storage drive instead of archive device. This should only be handled by those comfortable with linux bash shell, if unsure or concerned contact Support for process.)
Make sure to only run against drives listed in the above mdadm --detail /dev/md99 command. We can find archive disks using the command: # disk_monitoring_logger.py
E represents External Drive (Archive) in the above output
# mkfs.xfs -f /dev/sdX -- where X is the drive letter assigned
Note: This will format the data on the drive and allow us to re-use
Navigate to Configure > Backup Copy Targets section > select cold backup copy target > click "enable" and "Scan for media" to ensure no mount or communication errors.
If the issue persists, power cycle the appliance to ensure there are no communication errors between Appliance and the Recovery Archive device.
1. Shutdown the appliance.
2. Disconnect the cable(s) connecting the archives to the appliance.
3. Disconnect the power cable from the appliance.
4. Hold the power button down on the appliance for 15 seconds with the power cable disconnected.
5. Reconnect the power cable to the appliance and boot it up.
6. After it has been up for 1 minute, re-attach the archive unit.
7. Power on the Archive RXDA or Dock, navigate to configure > backup copy targets, and select archive device > "Erase" > and then click "Scan for media" to ensure no errors. Afterward, trigger cold backup copy job
