Moving EMC VNX5400

We are looking at moving one of our EMC arrays to a new data center in a few weeks. I am wondering what the best practice is for this as well if anyone has any documentation they can reference.  We are going to need to change the IP address on the device as well as temporarily stop replication from three other VNX's.  Unfortunately we no longer have support on these devices so I am unable to reference anything from the EMC portal.

Thank You

Shutting down the VNX is straightforward but please read this carefully first and make sure you follow the procedure.
1. Stop all host I/O
2. Disable any replication
3. Turn off the Fibre Channel switches or iscsi switches
4. Power off the DPE (Disk Processor Enclosure) using the SPS power switches - this triggers an orderly shutdown of the array. This will usually take a couple of minutes so be patient. The SPS is the mini-ups that keeps the brains of the array alive long enough to flush out write cache to the disk. *DO NOT* disconnect the DPE power cables until it has completed or you risk getting corrupted data.
5. Carefully label the disk shelves and cabling. Take photos. Everything **must** be reinstalled and cabled exactly as it was. Do not skip this step!!
6. You can now safely shut down the disk shelves and remove everything for transport.

Reinstallation is a reverse of the above. Pay attention to the disk shelf numbering and cabling. If you get this wrong, you'll lose access to the data or, worst case, cause large scale corruption.

Second, changing the IP address is also staightforward. See this article for step-by-step instructions: https://davidring.ie/2013/11/15/emc-vnx-changing-storage-processor-ip-name/

Easy!

How to change the management IPs of a VNX Unified Array

created by Ankit on Dec 5, 2012 5:08 AM, last modified by Ankit on Dec 5, 2012 5:09 AM

Version 1



As your enterprise network expands, there may come a time when you need to change the IPs on your array.  On a unified array, it can get a little tricky, so a primus solution emc279637 has been created along with a video demonstration, to help guide you on your way.

 

A couple of things to note:
1.This procedure is not valid for BLOCK Only arrays (like the VNX 5100) as well as gateway arrays (like the VG2 or VG8)
2.You will need a null modem serial cable to connect to the back of the control station
3.The procedure is broken down into two demonstrations•Part 1: Changing IPs to a different subnet
•Part 2: Changing IPs within the same subnet

4.This will disrupt access to Unisphere, but WILL NOT impact access do data.

 

 

You can find the video demonstration here: https://support.emc.com/media44409

 

For Instructions on how to change ip/subnet on block only arrays please, refer to primus emc60751
