Share the VMDK HDD with 2 Vm's

Hi All,

I have a requirement of creating Oracle Linux Cluster with Node 1 and Node 2 should have 130 GB HDD local and 150 GB HDD should be accessible to both the Node1 and Node1.

I have created the Node 1 VM and Node 2 VM.(both in Thick Lazy zeroed format.)

Attached the another hard disk of 150 GB to Node 1 VM  and Node 2 VM selecting as existing HDD and selected SCSI 1:0 , with  Independent persistent as checked.

when I am trying to power on the VM I am getting the error as

"unable to access file (storagename) hdd.vmdk since it is locked"

Please let me know am I missing something else to configure here.

Thanks a ton in advance for your help.
