RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Product Errata RHEA-2015:2342 0 normal SHIPPED_LIVE libstoragemgmt bug fix and enhancement update 2015-11-19 10:30:44 UTC

Description Bruno Goncalves 2014-11-06 09:53:33 UTC 
Description of problem:
Traceback when trying to map a lun to specific initiator using targetd plugin.


Version-Release number of selected component (if applicable):
# rpm -qa | grep libstoragemgmt
libstoragemgmt-1.0.0-4.el7.x86_64
libstoragemgmt-python-1.0.0-4.el7.noarch
libstoragemgmt-targetd-plugin-1.0.0-4.el7.noarch


How reproducible:
100%

Steps to Reproduce:
1.Create VG to be used by targetd
# vgcreate vg-targetd /dev/loop0

2. start targetd
service targetd restart
Redirecting to /bin/systemctl restart  targetd.servic

3. start libstoragemgmt
service libstoragemgmt restart
Redirecting to /bin/systemctl restart  libstoragemgmt.service

4. Create a LUN
lsmcli  -u "targetd://admin@localhost" volume-create --name='lsm-basic-test-lun' --size=2G --pool='vg-targetd' --provisioning='DEFAULT'

5. Try to map the LUN to a IQN

Comment 6 Bruno Goncalves 2015-08-14 08:18:33 UTC 
Tested using libstoragemgmt-1.2.3-3.el7, the volume-mask now requires access group ID, the problem is targetd on RHEL-7.2 (targetd-0.7.1-1.el7.noarch) does not support it.

# lsmcli  -u "targetd://admin@localhost" access-group-create --name test --init iqn.1994-05.com.redhat:cbc17c91e2b --sys targetd
NO_SUPPORT(153): Please upgrade your targetd package to support access_group_create() 


Testing using targetd from Fedora (targetd-0.8.3-1.fc22.noarch) works well.

# lsmcli  -u "targetd://admin@localhost" volume-create --name='lsm-basic-test-lun' --size=2G --pool='vg-targetd' --provisioning='DEFAULT'
