Unable to join EMC Celerra / CLARiiON into domain – Status: Not logged in

clarrionAt a customer site I saw a strange behavior between two EMC NS-480 systems.

It was impossible to bring the two Celerras and the two CLARiiONs into one domain.

If you logged into with one of the CLARiiONs SP IP-addresses into Unisphere you could see all 4 systems, but both Celerras showed “Not logged in” as status.

The other way around I couldn´t even login with Unisphere on the control stations with the user “nasadmin” and the scope “global”. And for sure if I selected the scope local, I didn´t see any of the systems, expect the Celerra i connected to.

Resetting the nasadmin password via CLI with the command..

nas_storage -modify id=1 -security

…didn´t bring any success.

After involving the EMC support and some hours later we found a working solution to get rid of this error / bug:

-Connect via putty to both control stations

-Browse to folder /nas/http/domain

-Take a backup of all files inside this folder

-Delete all files inside this folder (you may need to login as root)

-curl -kv “https://AAA.AAA.AAA.AAA/cgi-bin/set_incomingmaster?master=BBB.BBB.BBB.BBB ”
(AAA = IP address control station / BBB = IP address domain master)

– /nas/sbin/naviseccli -h  BBB.BBB.BBB.BBB domain -add AAA.AAA.AAA.AAA
(AAA = IP address control station / BBB = IP address domain master)

When executing the command in the last step the files you deleted on the beginning should be recreated. If you now login to the system (CLARiiON or Celerra) you should now see all systems in one domain and you can “jump” to each system from a single Unisphere GUI.

Please note that you may need to relogin into Unisphere, if you had opened a session during this process.
