| Fixed In Version: | Doc Type: | Bug Fix | |
| Doc Text: |
Cause: iscsiadm did not parse the hostname and port properly when they were passed into discovery and login commands.
Consequence: The login or discovery operation would fail, because iscsiadm would not be able to fine the record for the portal.
Fix: The iscsiadm portal processing was modified to check for ports after hostnames.
Result: Hostnames are now supported as portal arguments in iscsiadm.

Login to [iface: default, target: iqn.1994-05.com.redhat:tgtd-1, portal: ::1,3260] successful.
Looks like there was some regression using localhost IPV6 format (::1).
If add it [] ([::1]) works.
