Question
What is the process for changing the name of EMC X-Bricks?

Facts
EMC X-Bricks

Answer
Customers may choose to rename their EMC X-Bricks and the following is the process and CLI command structure to implement this change.

The Storage Controllers should all have their default generic names:
X1-SC1
X1-SC2
X2-SC1
X2-SC2
[...]
 
The cluster name is unique and assigned during install, run show-clusters-info to view that name:

All X-Bricks that are in that cluster, whether they were added as part of expansion or original, will use that cluster name.
 
The Brick-Name will show as X1, X2, etc. when running the show-storage-controllers-info command:

 

You can also use the show-bricks command to get X-Brick and cluster names.
 
All IP addresses are defined by the customer:

• X-Brick IP addresses: Four per X-Brick

• Controller IP addresses: Two per controller, as follows:

  • Management Interface: Used for management and monitoring

  • IPMI: Used for "lights out" remote access to the storage controller

Use the following commands to check/change Storage controller host names:

Check/Change Storage Controller Name:
xmcli (tech)> show-storage-controllers
SC Name:
X1-SC1
X1-SC2

Example of renaming both storage controllers for X-Brick-1:
xmcli (tech)> rename sc-id=”X1-SC1″ new-name=”XBrick1-SC1″
xmcli (tech)> rename sc-id=”X1-SC2″ new-name=”XBrick1-SC2″
