ERROR clariion_mgmt -start ххх -use_proxy_arp

Hello all!
We have Celerra NX4 with one Data Mover.
We wish to change IP addresses SPA and SPB on storage system. It is necessary therefore that the storage system was in our internal network (192.168.ххх.ххх) instead of used standard IP addresses like as 128.221.ххх.ххх

As I know, it's necessary to resolve proxy-ARP, but when I used command:
/nasmcd/sbin/clariion_mgmt -start -spa_ip 128.221.ххх.ххх -spb_ip 128.221.ххх.ххх -use_proxy_arp
there was an error:
Error 11: Invalid public IP address for SPA.
If I used:
/nasmcd/sbin/clariion_mgmt -start -spa_ip 128.221.ххх.ххх -spb_ip 128.221.ххх.ххх -use_nat
Error 11: Invalid public IP address for SPA.

when i used:
/nasmcd/sbin/clariion_mgmt -info
Error 12: Not configured

/nasmcd/sbin/clariion_mgmt -stop
Error 36: Public IPs for SPA and SPB have not been setup.

I do not understand in what a problem. Have you any ideas?

ok, so if you are trying to switch to 192.168.x network then your command should specify IP addresses you want to assign to your SPs ..not what's currently assign to them. With Proxy ARP enabled on the backend storage array storage processors have their IP addresses set to be in the same subnet as the Control Station's external network interface, while still wired to the Control Station's private network. The Control Station acts as a bridge and forwards network (Ethernet) packets from the public network to the backend storage array SPs. So you have to make sure that control station is on the same 192.168.x network as what you are trying to change your SPs to. In this example i have my control station assigned ip address 192.168.10.3 and i am changing SPA and SPB to 10.1 and 10.2

/nasmcd/sbin/clariion_mgmt -start -spa_ip 192.168.10.1 -spb_ip 192.168.10.2 -use_proxy_arp

I didn't change SPs IP on storage system. But I tried to configure the file /etc/hosts
Also I edited /nas/site/sp_info
I used one of articles, but then after this error have returned an initial condition of the files

don't modify files manually. You need to use the procedure that will do it for you. Take a look at this solution:

can you post output from "cat /etc/hosts | grep -i clariion" ..before you made manual changes to it.

I would suggest to open a service request and ask EMC customer service to fix it - preferrably through dialin or Webex

there is output:
[nasadmin@nx4cs ~]$ cat /etc/hosts | grep -i clariion
128.221.252.200 A_SL7Exxx SPA # CLARiiON SP
128.221.253.201 B_SL7Exxx SPB # CLARiiON SP
