A SAN administrator recently installed a storage encryption switch on a Fibre Channel Fabric.
Shortly after the deployment, several new VMFS5 datastores recently created were dismounted.
Attempts to manually mount them fail. VMFS5 upgraded datastores are unaffected. All Storage
arrays in use support VASA and VAAI.
What is the root cause of this problem?
A.
All newly created VMFS5 datastores are tagged ATS_Only. The storage encryption switch
blocks the ATS command.
B.
All newly created VMFS5 datastores are tagged XCOPY_Only. The storage encryption switch
blocks the XCOPY command.
C.
All newly created VMFS5 datastores are tagged WRITE_SAME_Only. The storage encryption
switch blocks the WRITE_SAME command.
D.
All newly created VMFS5 datastores were formatted with 1MB block size. The storage
encryption switch does not support this block size.
