The ISO images of the guest operating system scripts are loaded on the Virtual Storage Console for VMware vSphere server. To use them to set the storage timeouts for virtual machines, you must mount and run them from the vSphere Web Client.
If your environment includes multiple vCenter Servers, you must select the server that contains the virtual machines for which you want to set the storage timeout values.
Log in to the virtual machine and run the script to set the storage timeout values.
