Hi Pan, I checked the product identification definition in T10, I did not found that the LUN exported by the iSCSI target should be “Virtual disk”, it is vendor specified. Actually “Virtual disk” is the product identification name used by IET(iSCSI Enterprise Target, which is a vendor ID registered in T10 , http://www.t10.org/lists/vid-alph.htm#VID_V) As you see, we use the vendor ID Intel, product name can be specially in anyway. Thanks.

If we use spdk-iscsi to connect librbd, and input lsscsi, the device name is “Ceph rbd”. [cid:image003.jpg@01D2547B.AAF9E4A0] If we use the well-known tgtd to connect librbd, the device name is “VIRTUAL_DISK”: [cid:image005.jpg@01D2547B.AAF9E4A0] I prefer “VIRTUAL-DISK” to “Ceph rbd”: 1) The user doesn’t need to care it is a ceph a not. 2) From the usage: http://sg.danny.cz/scsi/lsscsi.html, “VIRTUAL-DISK” is introduced. What’s your opinion? Thanks Pan Email Disclaimer & Confidentiality Notice This message is confidential and intended solely for the use of the recipient to whom they are addressed.
