Issue:
"An unexpected error was received from the ESX host while
powering on VM vm-329.
Reason: Failed to lock the file.
Cannot open the disk
'/vmfs/volumes/4fa9769c-f8aaa808-ee31-00221924bc69/db07/db07_10.vmdk' or one of
the snapshot disks it depends on
Cause:
Don't mix up physical and virtual
compatibility mode for the RDMs with "SCSI Bus Sharing" for the
controller. Only in case of a single host, the "SCSI Bus Sharing" for
the controller (not the disks) has to be set to virtual.
Resolution:
You
need to change setting for SCSI controller for the VM
If you
are setting MSCS across ESXi hosts, then make SCSI controller to “Phyical” in
both the VMs.
If
you are setting MSCS in a single ESXi host (both node in same host) ,then make SCSI
controller should be “Virtual” in both the VMs.
You
need to power off the VM for doing this setting.
VM->edit
setting-> scsi controller (of rdm)-> phyical /virtual
