When performing SAN management functions in a dual fabric SAN, perform these functions one fabric at a time. Doing so will minimizes any issues that arise in that fabric.  Leaving the remaining fabric intact and the SAN operational should issues be encountered. All operations should be performed on only one fabric at a time. It is encouraged to perform a host level check out once the one fabric code upgrade is completed. If any unforeseen side effects disturb the operation of that fabric, then the other fabric will still be operational.
