2. Gather and record IP address and disk status information about the
server: See Step 2: Gathering information about the server or node on
page 88 .
3. Back up the server’s configuration: See Step 3: Backing up the server
configuration on page 90 .
4. Physically locate the server: See Step 4: Locating the server on
page 90 .
5. For cluster nodes, save the preferred mapping, and migrate EVSs to a
different node in the cluster: See Step 5: Save the preferred mapping
and migrate EVSs (cluster node only) on page 91 .
6. Physically replace the first disk: See Step 6: Replacing a Server’s Internal
Hard Disk on page 93 .
7. Synchronize the first new disk and the existing disk: See Step 7:
Synchronizing server’s new disk on page 100 .
8. Physically replace the server’s second hard disk: See Step 8: Replacing
the server’s second disk on page 101 .
9. Synchronize the second new disk and the first new disk: See Step 9:
Synchronizing the second new disk on page 101 .
10. For cluster nodes, restore migrated EVSs to their preferred node: See
Step 10: Restore EVSs (cluster node only) on page 101 .
When performing parts of the disk replacement process, you must access
the Linux operating system and/or the Bali console of the NAS server/
node. Instructions on how to access these components are provided in
Accessing Linux on the server and node on page 81
Accessing Linux on the server and node
To run some of the commands, you must access the Linux layer of the NAS
server or node using one of two methods:
• The serial (console) port, located on the rear panel of the server. See
Using the Serial (Console) Port on page 81 for more information.
• SSH connection. See Using SSH for an Internal SMU on page 82 or Using
SSH for an External SMU on page 82 ,
Using the Serial (Console) Port
Use the terminal emulator and null modem cable to access the NAS server’s
Linux operating system.
Procedure
1. Configure the terminal emulator as follows:
• Speed: 115200
• Data bits: 8 bits
• Parity: None
• Stop bits: 1
