Did you check out the gwcli man page and upstream ceph doc: http://docs.ceph.com/docs/master/rbd/iscsi-target-cli/ Let me know what is not clear in there. There is a bug in the upstream doc and instead of doing > cd /iscsi-target/iqn.2003-01.com.redhat.iscsi-gw:<target_name>/disks/ you do > cd /disks in step 3. Is that the issue you are hitting? For gwcli, a client is the initiator. It only supports one way chap, so there is just the 3 commands in those docs above. 1. create client/initiator-name. This is the same as creating the ACL in targetcli. > create iqn.1994-05.com.redhat:15dbed23be9e 2. set CHAP username and password for that initiator. You have to do this with gwcli right now due to a bug, or maybe feature :), in the code. This is simiar to doing the set auth command in targetcli. auth chap=<user_name>/<password> 3. export a image as a lun. This is equivalent to creating the lun in targetcli. disk add rbd.some-image > > (or see this page <http://www.asiaa.sinica.edu.tw/~cschen/targetcli.html>) > > #targetcli ls > o- / > ......................................................................................................................... > [...] > o- backstores > .............................................................................................................. > [...] > | o- block > .................................................................................................. > [Storage Objects: 1] > | | o- vmware_5t > .......................................................... > [/dev/rbd/rbd/vmware_5t (5.0TiB) write-thru activated] > | | o- alua > ................................................................................................... > [ALUA Groups: 1] > | | o- default_tg_pt_gp > ....................................................................... > [ALUA state: Active/optimized] > | o- fileio > ................................................................................................. > [Storage Objects: 0] > | o- pscsi > .................................................................................................. > [Storage Objects: 0] > | o- ramdisk > ................................................................................................ > [Storage Objects: 0] > | o- user:rbd > ............................................................................................... > [Storage Objects: 0] > o- iscsi > ............................................................................................................ > [Targets: 1] > | o- iqn.2017-12.asiaa.cephosd1:vmware5t > ............................................................................... > [TPGs: 1] > | o- tpg1 > .................................................................................................. > [gen-acls, no-auth] > | o- acls > ......................................................................................................... > [ACLs: 12] > | | o- iqn.1994-05.com.redhat:15dbed23be9e > .................................................................. > [Mapped LUNs: 1] > | | | o- mapped_lun0 > ............................................................................. > [lun0 block/vmware_5t (rw)] > | | o- iqn.1994-05.com.redhat:15dbed23be9e-ovirt1 > ...........................................................
