Check the disk sharing instructions from MSCS cluster guide from http://pubs.vmware.com/vsphere-51/topic/com.vmware.ICbase/PDF/vsphere-esxi-vcenter-server-511-setup-...

Note that linux clustering is not supported.

You will have to chane the scsi controller sharing mode depending on all vms on same host or multiple hosts. The detailed instructions for this setp is shared in the mscs guide that you can use as reference.

first use the following step.

1.Create a folder named as cluster on /vmfs/volume/storage path/cluster

2. Chmod –R 755 cluster/

3.Create a hdd space on this cluster folder size as 10000Mb.

Vmkfstools –c 10000M –d thick –a lsilogic cluster.vmdk

then add scsi controller on physical mode on vm or use abhilash link.
