when CS1 is primary i can see the gui and also to log in successfully. when CS0 is primary i get nothing.

Is CS1 responging via the unispere interface at all?  Can you see the gui just not log in,  or no gui at all?

yes i cas access both CS0 and CS1 with ssh.

After running your cs_standby,  can you ping/ssh the interface on the control station?

yes i am aware of the time that the process takes. right now its about 2 hours after the cs_failover finished.

How long did you wait? It usually takes 10-15 minutes

There is usually a virtual IP which failover/failback to the primary CS. Try pointing your browser to that IP instead of the CS IPs which stays with it. Also check whether all the NAS partitions are getting mounted on CS0. If not mount it manually and wait for few minutes and the GUI will open.

I believe the virtual IP for dual control stations isn’t created by default

Check the documentation about control station IP alias

i have compered between the two CS mount list. both shows the same info when each is the Primary CS:

thanks

Hey Balaji and thank you for your time and effort.

i have found a few things interesting:

1. at the messages file  i have found this line --> Jun 11 10:25:10 xxxx-cs0 get_backend_status: Storage System xxx00121000xxx not responding to ping !, however i am able to ping SPA and SPB from the ssh session to CS0.

2. proxy arp is running:

Public IP address for SPA: 192.168.100.246

Public IP address for SPB: 192.168.100.247

Start on boot            : yes

Current implementation   : Proxy-ARP

Status                   : Started

3. storage check failed:

[root@xxxx-cs0 nasadmin]# nas_storage -c -a

Discovering storage on xxxx-cs0 (may take several minutes)

Error 5026: xxx00121000xxx d7, Unknown, doesn't match any storage profile

Error 5017: storage health check failed

xxx00121000xxx d7, no storage API data available

4. /nas/sbin/navicli -h spa domain -list ---> looks right to me but i paste it anyway

Node:                 CS0
IP Address:           192.168.100.247
Name:                 SPB
Port:                 80
Secure Port:          443
IP Address:           192.168.100.246 (Master)
Name:                 SPA
Port:                 80
Secure Port:          443
IP Address:           192.168.100.248
Name:                 Celerra_xxxx-cs0
Port:                 80
Secure Port:          443

6. nas is already mounted

7. nas service is running

thank you very much for your help and time this is really appreciated!

You should be finding a primus solution by simply searching (support.emc.com)

"Error 5026: xxx00121000xxx d7, Unknown, doesn't match any storage profile"

It says you may have deleted unused LUNs from backend without deleting the same from File side. Hope this solution will resolve your issue.
