I'm looking for a procedure that outlines the proper steps to change the IP Address Information of an EMC Celerra NS350 NAS. I’m very familiar with the Clariion SAN’s, but not the Celerra product line. From what I’ve read I can’t simply open a web browser and use <storage processer IP>/setup like you can on the Clarrion’s.
Any help would be appreciated.
Thank you,

How to modify the SP IP Addresses for Proxy ARP implementations with NAS 5.5.30.x (applies only to NS20FC & NS40FC models)
Caution: Changing SP IP Addresses in a Proxy ARP implementation requires rebooting the backend storage array SPs to change their network configuration. Only one SP will be rebooted at a time to make the process as non-disruptive as possible. While the SPs are rebooting, the backend storage array and Celerra system performance will be degraded. The estimated time for the upgrade is 15 minutes.
Important additional information
After changing the IP addresses, the following errors may occur when the script runs the nas_storage -check -all command:
!!!! In any case, after the nas_storage -check -all command is successful, update the CLARiiON security cache login information the Celerra uses to authenticate with by running the nas_storage -modify id=x -security command and enter the Clariion Domain security username and password !!!!
How to modify the SP IP Addresses for Proxy ARP implementations with NAS 5.5.31.x (applies to all NS20/NS40,NS20FC/NS40FC systems)
Beginning with NAS code 5.5.31, all new installs of NS20, NS40 and the FC models, will be converted to Proxy ARP during the CSA configuration process. For NAS code 5.5.31 it is not necessary to download the clariion_mgmt script as described above. In this code version please use the -modify option to change the IP address. There is also no need to run clariion_mgmt -stop before changing the IP address.
# /nasmcd/sbin/clariion_mgmt -modify -spa_ip xxx.xxx.xxx.xxx -spb_ip xxx.xxx.xxx.xxx
Checking if running as root...yes
Checking if model is supported...yes
Checking for integrated system...yes
Checking if interface eth3 is configured...yes
Checking if interface eth3:1 is configured...no
Checking if interface eth3:2 is configured...no
Checking if SP (10.64.247.141) is up...yes
Checking if SP (10.64.247.142) is up...yes
Checking if a gateway is setup for eth3...yes
Step 1/7: Setting up Proxy ARP for SPA on Control Station
Adding host specific route for SPA
Adding rules to allow outbound traffic from SPA
Adding ARP entry for SPA
Updating /etc/hosts entry for SPA
Step 2/7: Changing SPA IP address.
Changing SPA IP from 10.64.247.141 to 10.64.247.147 (subnetmask 255.255.255.0, gateway 10.64.247.1)
Step 3/7: Waiting for SPA to reboot.
Waiting for SPA to go down...done
Step 4/7: Waiting for SPA to boot up.
Waiting for SPA to come back up...done
Step 5/7: Waiting for CLARiiON software to start on SPA.

Step 6/7: Removing old Proxy ARP setup for SPA on Control Station
Removing host specific route for SPA
Removing rules that allow outbound traffic from SPA
Removing ARP entry for SPA
Step 7/7: Updating NAS database with SPA IP address
Updating SYMAPI database with new CLARiiON IP addresses...done

How to modify the SP IP Addresses for NAT implementations (for NAS code 5.5.30 on the NS20/NS40 platforms, though NAT could still be running on systems upgraded from NAS code 5.5.30)
Toddh,
you will need to run this command, replace 128.221.x with your ip addresses. Make sure Control station is configured for that network first and then run the command.
/nasmcd/sbin/clariion_mgmt -start -spa_ip 128.221.ххх.ххх -spb_ip 128.221.ххх.ххх -use_proxy_arp
So, based off what you told me this is what I invision needs done.
Should I be concerned about the host file?
Would it hurt to do a re-discover from the Celerra?
