Hello experts,

I have some problem about sg_persist command:

inquiry cdb: 12 00 00 00 24 00
VMware Virtual disk 1.0
Peripheral device type: disk
Persistent Reservation In cmd: 5e 02 00 00 00 00 00 20 00 00
persistent reservation in: transport: Host_status=0x10 [DID_TARGET_FAILURE]
Driver_status=0x08 [DRIVER_SENSE, SUGGEST_OK]

persistent reservation in: Fixed format, current; Sense key: Illegal Request
Additional sense: Invalid command operation code
Sense Key Specific: Error in Command byte 0

root@hosta:/root > sg_persist /dev/sdb

No service action given; assume Persistent Reserve In command
