[ovirt-devel] adding new paths to iscsi data storage domains

[Paul Dyer]

First of all, thank you for your time.   I must apologize that in this
install, I am using RHEV 3.4.5.    I will try to reproduce this on an ovirt
install.   I just need to create some paths to iscsi targets.

1.   This configuration has 2 physical hosts, Dell PE-R715 servers, with a
Dell PowerVault MD3200i iSCSI data storage domain.   The EM3 nic was the
original link.   EM4 was the new connection to storage.

2.   From the manager interface, I selected Storage tab, then the
kvm5DataDomain, then edit.   From the popup, I added the IP address under
Discovery Targets, then clicked the Discover button.    Then, clicked the
login arrow on the new targets discovered.

I have attached the engine and vdsm logs.   I was working on this at about
11:40am Feb 4th.

When setting the host in maintenance mode, then reboot, and Activate, the
new paths do not get a login.

Thanks,
Paul
