We are planning on performing some maintenance on our fibre channel SAN switches. To us it makes sense to failover the traffic to the FC switch that will remain up. I am looking for a script that will change the multipathing policy to fixed and set the preferred path to a nominated HBA. Alternately would a script to disable the paths be another option to consider?
I'm not sure which would be better.
We've got a shed load of LUNS which means it's impractical to do this manually. Powercli seems like sensible tool to automate this. Can anyone offer some help?
Thanks in advance
