Pinned topic Break Synchronous Mirror with no downtime

‏2013-01-25T21:36:29Z |
Here's the situation:

We have XIV1 and XIV2. We need to migrate data from XIV1 to XIV2, keeping the mapping to the server.

The way I have it set up is as follows:

  • Configure mirroring ports between the systems.
  • Add a mirror of the volume in question, make it a slave on XIV2.
  • On XIV2, change the role to be master.
  • On XIV1, change the role to Slave.
  • Remove the mirror.

The only problem with this setup is that the LUN mapping doesn't apply to the slave volume. So when I remove the volume from XIV1, the volume goes down on the server while I map it on XIV2.

Can I map the slave volume to the target server without breaking anything, so that when the mirror fails over, the mapping will already be there? Is there a better way to do what I'm trying to do?

    What are the versions of the microcode your XIVs are running?

      10.2.4.c-1 ; is that the version you're referring to?
