Re: iSCSI: INQUIRY, version descriptor

["Nandakumar Ramamurthy" <nramamur@npd.hcltech.com>]

Hi Luben,

The SPC-2 has this to say :

"The version descriptor fields provide for identifying up to eight
standards to which the device claims conformance."

"It is  recommended that the first version descriptor be used for the
SCSI architecture standard, followed by the physical standard, followed
by the physical/mapping protocol if any followed by the appropriate SPC
version, followed by the device type command set, followed by a
secondary command set if any."

Consider a target device that conforms to more than eight standards for the
SCSI architecture, and physical standards. In this case the INQUIRY response
data will not contain iSCSI version descriptor.  What will be the actions
taken by
the iSCSI target/initiator on finding a target device not conforming to
iSCSI ?
