FRU Replacement Guide
3 Controller Node Replaceable Units
15
A work table is provided at the end of this section for your convenience, to store all of the information needed for a
chassis replacement.
To replace a Controller Node chassis, proceed as follows:
1.
If the failed chassis is the Management Node chassis, fail over the Management Node to another Controller Node.
a) Open an SSH session to any Controller Node.
You must obtain the IP addresses of the Controller Node ahead of time.
b) Use the following command to determine the virtual IP address of the Management Node.
grep dmachine.amplistor.com /etc/hosts | grep -v 127.0.0.1 | awk '{print $1}'
The output of this command is the virtual IP address of the Management Node. For example,
172.16.63.154
c) Open an SSH session to the Management Node using the virtual IP address obtained in the previous substep.
d) Exit the OSMI menu.
The Linux prompt appears.
e) Copy or write down the hostname in the Linux prompt.
f) Log into the CMC.
g) Navigate to
Dashboard
>
Administration
>
Hardware
>
Servers
>
Controller Nodes
, and select the failed
Controller Node.
h) Compare the hostname of the failed node, as displayed in the CMC, to the hostname you saved from substep e.
i) If the failed node is the Management Node, fail over the Management Node to another Controller Node.
For instructions on how to fail over the Management Node, see
Managing Hardware
in the
HGST Active
Archive System Administration Guide
.
2.
Enable the location LED on the Controller Node.
a) In the CMC, navigate to
Dashboard
>
Administration
>
Hardware
>
Servers
>
Controller Nodes
.
b) Select the correct node.
c) In the
Commands
pane, click
Location LED On
.
A blue LED on its front and back panels is now blinking.
3.
Shut down the Controller Node from the CMC.
Note:
Save the node's hostname in your worktable under
Original Hostname of Node
.
a) In the CMC, navigate to
Dashboard
>
Administration
>
Hardware
>
Servers
>
Controller Nodes
.
b) Select the desired Controller Node.
