I have two Windows 2008 R2 VM's setup with RDM's in a Failover cluster. When I present the Lun to the VM I set the PSP to MRU. I noticed when I go to Storage -> Devices some Lun are showing RR while other are MRU.
I have also noticed when I click on some LUN in the Manage Paths dialog hags on "Loading" for several minutes.
This is a large cluster for our Core DB. I am not seeing any disk latency alerts yet I am still very nervous about this since VMware states only MRU is supported with 5.1. I have already set the P.R reservations....
I know you can change the PSP on the fly but nervous..
Thoughts on this anyone or am I just being to gun shy? What would happen if I leave it as is? User are not complains of performace issues?
