Hi,

following setup:
host1 hosts vsan1 on local datastore
host2 hosts vsan2 on local datastore

the ps1 script sets the multi path on vmware to round robin.
Is it possible to set the preferred path for host1 to vsan1 only if this fails to vsan2
and the preferred path for host2 to vsan2 only if this fails to vsan1

IMHO this would speed up the storage, as host1 does not need to leave the host to access the VSAN.

TIA

Hi denkteich,
You are telling about Most Recently Used policy to use only one path.
But Round Robin is giving you better performance, that is why we are setting this policy with the help of rescan script.
