Synchronizing a new disk

After replacing a hard disk, the new disk in the server's internal RAID
subsystem must be synchronized with the older disk.

Run the script /opt/raid-monitor/bin/recover-replaced-drive.sh, which
will partition the disk appropriately, update the server's internal RAID
configuration, and initiate the rebuilding of the RAID pair.
Rebuilding the RAID pair ensures all data is accurate across both hard
disks.
After the script has finished, follow these steps:
a. Check the status logging into the NAS OS console (Bali).
b. Issue the command: chassis-drive-status
c. Repeat until all partitions are synchronized.
The RAID system rebuilds the disk as a background operation. The
events are logged as the RAID partitions rebuild and become fully fault
tolerant. The rebuild process can take up to an hour. The status indicator
indicates normal operation (solid or flashing blue) once the RAID
configuration has been repaired.
Log out.
Properly dispose of the used HDD. Do not attempt to re-install or re-use
the used HDD.
Wait until the LEDs on the front of the server slow to indicate normal
activity.
Use a serial cable connected to the serial (console) port of the server to
access the Bali console.
Once you have successfully logged in, select the server or node that has
the disks you want to synchronize.
Run the chassis-drive-status command, and look at the values in the
Status and % Rebuild columns for each device.
• The values in the Status column should be "Invalid."
• The% Rebuild column should not display any values.
Run the script /opt/raid-monitor/bin/recover-replaced-disk.sh.
This script partitions the replacement disk appropriately, updates the
server's internal RAID configuration, and initiates rebuilding the replaced
disk.
The RAID system rebuilds the disk as a background operation, which
takes approximately 50 minutes to complete. Events are logged as the
RAID partitions rebuild and become fully fault tolerant.
Monitor the rebuilding process by running the chassis-drive-status
command, and check the values in the Status column for each device.
The values in the Status column should be:
