Change Celerra IP Address Information

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.

1. Download the latest version of clariion_mgmt script: http://powerlink.emc.com/km/live1/en_US/Offering_Technical/Technical_Documentation/clariion_mgmt.zip
   Note:  If the system is running NAS 5.5.31, you do not have to download the clariion_mgmt.zip file. Just use the /nasmcd/sbin/clariion_mgmt executable.
   
   
2. Unzip and copy the script to portable media (floppy diskette or CD-ROM). The script must be run on the Control Station.
   
   
3. Insert the portable media into the Control Station.
   
   
4. From Celerra Manager, select Celerras > > Tools > SSH Shell.
   
   
5. From the SSH session, log in to the primary Control Station as nasadmin. Change to the root user by running the following command:
   su root
   
   
6. Mount the media on the Control Station (/sbin/mount /mnt/floppy or /sbin/mount /mnt/cdrom).
   
   
7. Change the working directory to the mount location (cd /mnt/floppy or cd /mnt/cdrom).
   
8. Copy the 'new' clariion_mgmt script to the following directories, overwriting the existing version: /nasmcd/sbin and /nas/sbin
   Note:  You must use only the Powerlink version of the clariion_mgmt script when converting a 5.5.30 system from NAT to Proxy ARP
   
9. Confirm the current implementation of the system:
   
   # /nasmcd/sbin/clariion_mgmt -info
   Public IP address for SPA: 10.64.247.147
   Public IP address for SPB: 10.64.247.148
   Start on boot           : yes
   Current implementation  : Proxy-ARP

    done
    
    
11. Verify that Proxy ARP is no longer configured:
    
    # /nasmcd/sbin/clariion_mgmt -info
    Error 12: Not configured
    done
    
    
12. Reconfigure the system for Proxy ARP using the new SP IP addresses:
    
    # /nasmcd/sbin/clariion_mgmt -start -spa_ip 10.64.247.141 -spb_ip 10.64.247.142 -use_proxy_arp

    /nas/bin/nas_storage -check CK200073500354 failed! You will have to run this manually!
    
    
13. Re-check for the new configured SP IP Addresses
    
    # /nasmcd/sbin/clariion_mgmt -info
    Public IP address for SPA: 10.64.247.141
    Public IP address for SPB: 10.64.247.142
    Start on boot           : yes
    Current implementation  : Proxy-ARP
    Status                  : Started
    

Important additional information

After changing the IP addresses, the following errors may occur when the script runs the nas_storage -check -all command:

• Error 3502: Storage API code=3057: SYMAPI_C_INVALID_IP_ADDRESS
  The ip address provided is not valid
  
  
  Solution & Additional Steps Required:
  
  1) Run the /nas/bin/nas_storage -modify id=x -network -spa xxx.xxx.xxx.xxx -spb xxx.xxx.xxx.xxx command to update the SYMAPI DB with the new IP addresses of the SPs, then rerun the nas_storage -check -all command.
  
  2) Then update the local CLARiiON security cache files on the Celerra Control Station by running nas_storage -modify id=x -security
  
  
• Error 5017: storage health check failed
  CK20007350xxx  write cache disabled
  
  
  Solution: After rebooting the SPs, the SPS will be recharged. The write cache remains disabled until the SPS is fully charged and operational. Please wait at least 30 minutes before running nas_storage -check -all again.

!!!!    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.

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)

1. Download the latest version of the script from:
   
   http://powerlink.emc.com/km/live1/en_US/Offering_Technical/Technical_Documentation/clariion_mgmt.zip
   
   Note:  If running NAS 5.5.31 code or later, you do not need to download the clariion_mgmt.zip file separately.  Use /nasmcd/sbin/clariion_mgmt.
   
   
2. Unzip and copy the script to portable media (floppy diskette or CD-ROM). The script must be run on the Control Station.
