There are many possible causes for the ProxySG to stop responding such as software/hardware defects, network connectivity issues, et c; however, a fault disk can be a likely culprit.
The following points can be helpful for further troubleshooting:
- The best way to determine this is to physically access the unit and view the front·panel LED's
- If one or more of the disk LED's are illuminated in red (on a multiple disk system), further troubleshoot by removing such disk(s)
- Sometimes simply reseating the disk drive will restore the device to normal functionality (if not, it is likely the disk is faulty)
- If reseating the disk successfully restores the unit, check for errors associated with this disk in the event log (https://<proxy.ip.address>:8082/eventlog/statistics) and follow the steps in the KB at the following link to reinitialize the disk as a possible solution: Reinitializing drives on a multi·disk ProxySG
- If reseating does not restore the disk, try swapping the disk with a "known good" disk from another slot (if the same LED stays red, it is possible the slot is faulty)
- If one of the bad disks is in slot 1, swap it with one of the "known good" disks from another slot (example: remove disk 1 and disk 2, place disk 2 in slot 1)
Often times following the steps above will restore the device to normal operating functionality but if the end result is that a disk or slot is completely inoperable, please contact Support for further assistance and possible RMA for replacement.
