Synchronizing A New Disk - Hitachi 3090 G2 Hardware Reference Manual

6. Replace the bezel .
7. Log in to the server as the root user.
a. Use SSH to connect to the server using the manager account. By default, the
password for the manager account is nasadmin, but this password may have
been changed.
b. To gain access as root, press Ctrl-D to exit the console, then enter su –.
When you are prompted for the root password, enter it for the root user
account. By default, the password for the root account is nasadmin, but this
password may have been changed.
8. 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.
9. 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.
10. Log out.
11. Properly dispose of the used HDD. Do not attempt to re-install or re-use the used
HDD.

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.
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.
