EMC – renaming the CX4 SP using natest.exe

We recently had to convert some old CX4-480s to 960s and rename them. For some reason we couldn’t change the names on the SPs or get them to join the Unisphere domain properly. EMC Support used a very useful tool called natest.exe to rename the SPs via a RemotelyAnywhere session. Here’s how to do it. Obviously you should use this tool with caution and only if instructed by support.

Log in to the affected SP with RemotelyAnywhere and fire up a command prompt.

You can then use natest to rename the SP, amongst other things.

selection: 1

supported: IPv6 VLAN
machine name: ERNIE
domain name:
reboot required: FALSE

selection: 2

Enter machine name: BERT

2: Set global properties
3: Do full refresh

Once you’ve set the machine name, back out of the utility and use Unisphere to reboot the SP. Once it has rebooted you should see the new SP name in Unisphere and you should then be able to join it to the domain.
