Quite a long time ago I asked about how to change the Gateway and Subnet mask addresses on a unified system. I know this is a global settings so it has to be done on the control station. I once receive a link how to do it by CLI but this articel took care of changing IP adreses not gateway and subnet.
So my questions are:
1) If I login with "root" to the control station there is "control station" properties and there fields (IP, Gateway,Subnet) which i can change witin the web GUI. Is this working?
2) Is there a reboot of the control station or SPs? ATM we are using the block part only.
3) is it save to do this?
PS: I've got an error on that machine (dashboard) that the power supply for enclsoure 0 SPB is faulted but when i check the hardware tabs everything is green?!
I assume you want to change the Gateway IP of the SP's, while changing the SP IP using 'clariion_mgmt command, it'll take gateway information from the CS only. Make sure CS IP or Gateway is changed then use command to change the IP of the SP
1) Type nas_cs -set command on CS 0: nas_cs -set -ip4address 10.240.210.110 -ip4netmask 255.255.255.0 -ip4gateway 10.240.210.1
Then failover to CS 1 and CS will reboot. On CS 1 repeat the above command.
2)Use clariion_mgmt: Starting the Proxy ARP service, assigning the IP addresses to the SPs, and updating the domain information, may take up to 15 minutes
# /nas/sbin/clariion_mgmt -start -spa_ip 10.240.210.112 -spb_ip 10.240.210.113
This will disrupt access to Unisphere, but will not impact access do data.
Thank you very much for your fast response. From the EMC technication support i receveid following information.
Login with root to the CS IP address, then change the Gateway and Subnet Settings which you find in "Control Station Properties". Reboot if necessary.
Login to the SPs Setup Page and change the Gateway and Subnet according to the CS information.
So this seems to be a more manual way how to do it? Will it work anyway?
Your way would be a manual change on the CS and an distribution of this values tot he SPs, is that correct?
Which one would you recommend? Please consider the system is already productive even if we only use block!
Thank you and all the best
Unfortunately the link you have provided to me is not accessable (access denied).
Could write me down the steps for updating the domain information for the domain?
Hi Duker, please see as below:
|Changing Control Station (CS) and Service Processor (SP) IP addresses on 126.96.36.199 VNX Unified systems|
|Need to change IP addresses on VNX Unified components|
|EMC Software: VNX Operating Environment (OE) for File 188.8.131.52 and later|
EMC Software: VNX Operating Environment (OE) for File 7.1 an later
EMC Software: VNX Operating Environment (OE) for File 8.1 and later
EMC Software: Unisphere version 1.1.25 and later

|This solution describes the steps to follow when changing the IP addresses on the VNX Unified system. There are two scenarios for changing IP addresses, which depend on whether the address change is on the same network or to a new and different network.|
CAUTION: Please note that in the case of multiple systems joined or managed in a multi-domain environment, the system that requires the IP address change needs to first be removed from the Domain so that it is a stand-alone VNX system.
IMPORTANT! This solution applies only to FILE OE versions at 7.0.35 and later: Refer to 77094 for the IP address change procedures for File OE versions 184.108.40.206 - 220.127.116.11For a video demonstration of how-to for both of the following IP address change procedures (to a new network and within the same network) search for media44409 at EMC Online Support.

Scenario I. Changing network address from one network to a new and different network (See Scenario II if only changing IP address within the same network):
# ping 18.104.22.168 [SPA]
# ping 22.214.171.124 [SPB]
3.Change the IP address on CS0 and then verify that CS0's IP address is properly updated to the domain:
# nas_cs -set -ip4address 10.240.200.50 -ip4netmask 255.255.255.0 -ip4gateway 10.240.200.1
4. For dual Control Station systems, failover to CS1, change CS1's IP address, wait for CS1's IP address to update in the domain:
# /nas/sbin/cs_standby -failover
b) Log in to CS1 and verify that CS1 is running as the "primary control station"
Note: It may take 10-15 minutes for NAS services to properly transition and startup on CS1
5. Failback to CS0, wait for CS0's IP address to update, then verify system management using Unisphere
a) Failback from CS1 to CS0
# /nas/sbin/cs_standby -failover
b) Log in to CS0 and verify that CS0 is the "primary" Control Station.
Note: It may take 10-15 minutes for NAS services to properly start
c) Verify that CS0's IP address has properly updated in the domain
# /nas/sbin/navicli -h 10.240.200.52 domain -list
d) Launch Unisphere, log in to either the CS or SP IP address, and then verify domain management functions.
