Troubleshooting
This section provides guidelines to some problems you may encounter:
• Handling Critical Arrays
• Handling Disabled Arrays
• PC hangs when card is installed.
Handling Critical Arrays
When your disk status turns critical, your array as a whole is still accessible, but one or more disks is faulty (depending
on your RAID level), and the array is in danger of failing.
To recover from this situation,
1. Backup your existing data.
2. Identify which disk is faulty.
You can refer to the LED lights on the enclosure Refer to the HRM Logical tab
and Event tab.
3. Re-insert the faulty disk or replace with a new disk.
The array will rebuild automatically if your auto-rebuild setting is enabled and you reseated the faulty disk.
Note: Click Rescan if the array still does not rebuild automatically.
4. If the new disk is added and it does not automatically start rebuilding, you can manually add the disk in
maintenance.
Log into the HRM Click
Logical Tab
Click Maintenance>Add Disk> select the appropriate disk
5. Rebuild should now start.
If rebuild does not start, click ‘Rescan’ on the left hand panel.
Note: Rebuilding an array takes on average 2 hours per 1 Terabyte of disk capacity. The process will scan through the
entire disk, even if you have very little used disk space.
