18. Reinstall the fan retention brackets. Do not over tighten the screws.
19. Reconnect the fan cable.
20. If you replaced only the first hard disk, continue with the next step. If
you have replaced both disks, reinstall the fascia.
21. Reconnect the power cables to the PSUs.
When the server starts, the LEDs on the front of the server flash quickly,
indicating that the server is starting up.
Step 7: Synchronizing server’s new disk
After replacing a hard disk, the new disk in the server’s internal RAID
subsystem must be synchronized with the older disk.
Procedure
1. Wait until the LEDs on the front of the server slow to indicate normal
activity.
2. Use a serial cable connected to the serial (console) port of the server to
access the Bali console.
3. Once you have successfully logged in, select the server or node that has
the disks you want to synchronize.
4. 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.
5. Run the script
/opt/raid-monitor/bin/recover-replaced-drive.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.
6. 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:
• “Good” for synchronized volumes.
• “Rebuilding” for the volume currently being synchronized.
• “Degraded” for any volume(s) that have not yet started the
synchronization process.
