We have storage maintenance activity in our environment and we need to disable 2 out of 4 LUN paths of each LUN presented to a set of esx hosts.
How to disable lun paths using powercli.
You can use the Set-ScsiLunPath cmdlet to disable and enable a specific path with PowerCLI: vSphere Documentation Center
Your maintenance will be on a Fabric ? If yes, take a look at this another thread to disable ptah for a specific HBA: Re: Disabling paths to migrate all FC storage connections to specified port on HBA
