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.

Description Martin Hoyer 2015-07-31 13:48:14 UTC 
Description of problem:
Cannot discover iSCSI target (LIO) on aarch64 with IPv6 

Version-Release number of selected component (if applicable):
targetcli-2.1.fb41-2.el7.noarch
iscsi-initiator-utils-6.2.0.873-30.el7.aarch64

How reproducible:
100%

Steps to Reproduce:
1.Create iSCSI target using targetcli
2.Try to discover the target
# iscsiadm -m discovery -t st -p ::1

Actual results:
iscsiadm: Cannot resolve host [::1]. getaddrinfo error: [Name or service not known]
iscsiadm: cannot resolve [::1]
iscsiadm: failed to add default portal
iscsiadm: failed to add target record
iscsiadm: No portals found

Expected results:
target discovered successfully
Comment 1 Martin Hoyer 2015-07-31 13:50:37 UTC 
kernel-4.1.0-0.12.el7.aarch64
Comment 3 Bruno Goncalves 2015-08-12 13:28:35 UTC 
It is not only on aarch64, I've also reproduced it on 7.2 Alpha on x86_64

# iscsiadm -m discovery -I default -p ::1 -t st
iscsiadm: Cannot resolve host [::1]. getaddrinfo error: [Name or service not known]

iscsiadm: cannot resolve [::1]
iscsiadm: failed to add default portal, ignoring target iqn.2009-10.com.redhat:storage-1
iscsiadm: failed to add target record
iscsiadm: No portals found

# uname -r
3.10.0-302.el7.x86_64

# targetcli-2.1.fb41-2.el7.noarch
Comment 4 Bruno Goncalves 2015-08-12 13:52:14 UTC 
Setting it as Regression as it works well on kernel -300 and fails on -301, probably due BZ#1136558
Comment 7 Andy Grover 2015-08-18 16:01:08 UTC 
Bruno or Martin, can you please attach your target config, '/etc/target/saveconfig.json'? Thanks.
Comment 8 Andy Grover 2015-08-18 16:05:01 UTC 
netstat -an output would also be great.
