Shutting down a server that you are replacing
On the server that you are replacing:
Procedure
1. From the server console, enter the
shutdown --powerdown
command.
2. Wait until the console displays
Information: Server has shut down
, and the
rear panel LEDs turn off. The PSU and server fans continue to run until you remove
the power cables from the PSU module. See the appropriate system component
section for more information.
Note: This specific
powerdown
command prepares the system for both
shipping and potential long-term, post-replacement storage.
3. Unplug the power cords from the power supplies.
4. For a node in a cluster, once the node is shut down, go to Home > Server Settings
> Cluster Configuration and delete the entry for the node that you are replacing.
5. Use the following rear panel figure and table to identify and label the cabling
placement on the existing server.
6. If cables are not labeled, label them before removing them from the server.
7. Remove all cables from the server, and remove the server from the rack.
8. Remove the rail mounts from the old server, and install them on the new server.
9. Remove the power supply from the old server, and install it in the new server.
10. Remove the bezel from the old server, and install it on the new server.
11. Insert the new server into the rack, and connect the power cords to the power
supplies.
Note: Do not make any other cable connections at this time.
Configuring the replacement servers
Before you begin
Obtain the necessary IP addresses to be used for the replacement server. Servers
shipped from the factory have not yet had the
nas-preconfig
script run on them, so a
replacement server will not have any IP addresses pre-configured for your use.
IP addresses are required for the following:
■
Eth1 (cluster IP) – 192.0.2.200/24 eth1
■
Eth1 (testhost private IP) – 192.0.2.2/24 eth1
■
Eth0 (testhost external IP, which might vary) – 192.168.4.120/24 eth0
For a single NAS server, when you run the
nas-preconfig
script, it reconfigures the
server to the previous settings. This step allows the SMU to recognize the server as the
same and to be managed.
