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 of problem:
working with the rhevm and iscsi I was trying to connect my host to my iscsi lun.
I was getting an error for command: /sbin/iscsiadm -m node -T Dafna-blonds-Linux -l -p 10.35.64.10:3260
after some digging we found that we have exceeded 190 targets on the same connection and there for were unable to login.
after removing the nodes under /var/lib/iscsi/nodes/*/*/default and discover again - we were able to connect again to the storage.
why are we limited to 190 targets?
Version-Release number of selected component (if applicable):
iscsi-initiator-utils-6.2.0.872-21.el6.x86_64
How reproducible:
Steps to Reproduce:
1. exceed 190 targets under same connection and try to login to lun
2.
3.
Actual results:
you cannot login
Expected results:
exceed 190 nodes limit
Additional info: vdsm log which can show the error we were getting
On a second thought, it does not seem to be that the db size puts the limit per se.
Thread-1245::DEBUG::2011-06-22 12:33:11,118::iscsi::372::Storage.Misc.excCmd::(addiSCSIPortal) '/usr/bin/sudo -n /sbin/iscsiadm -m discoverydb -t sendtargets -p 10.35.64.10:3260 --discover'
prints to stderr multiple lines like
iscsiadm: Could not add/update [tcp:[hw=,ip=,net_if=,iscsi_if=default] 10.35.64.10,3260,1 iqn.2010-03.com:server.target.moran-50g-07]
iscsiadm: Could not stat /var/lib/iscsi/nodes//,3260,-1/default to delete node: No such file or directory
reports success (rc=0) but presumably does not updates the discoverydb.
Does this make any sense?

This is a bug in the iscsi tools. We have been chasing this in another bz (https://bugzilla.redhat.com/show_bug.cgi?id=656284), but have not been able to replicate it lately. Is this a system in red hat, and if so can I login (send me the login info to mchristi).
