Hello,
i can't understand what is the best practice to manage a MSCS cluster into vmware enviroment.
My Esx 4.1 infrastructure is composed by a 4 cluster with 10 esxi hosts. A lot of vm has into a MSCS cluster with Raw device ( 240 raw device datastore) and i have a lot of performance issue and a lot of errors in /var/log/vmkernel with I/O failed.
I can't understand what is the best practice of vmware to manage a lot of MSCS cluster into Vms with Raw Device.
This is actual procedure when i create new vm with MSCS:
- I create vm in datastore
- In storage i present a NEW LUN at all Hosts for that Esxi cluster as RAW device
- Install MSCS service
I think that procedure is stable but it isn't correct, so i don't want present a LUN on a single host because i want keep redundancy of vm.
Thank You..
