    Question on adding additional iscsi storage to existing pool.  OVM 3.1.1

    Bob Weinmann
      OVM 3.1.1-485. Generic iscsi plugin. Equallogic SAN.

      We have a running pool with one server. Two repositories on iscsi volumes.

      The iscsi environment was configured on the OVM server using iscsiadm commands to ensure true multipathing across two NICs. We're not using a bond pair for iscsi traffic.

      I provisioned a third iscsi volume, discovered and logged in to the target from the server. A refresh of the SAN from OVM manager picked up the new disk.

      What I can't get past is presenting the volume to the OVM server so that I can create a repository.

      When I select the SAN in the storage window, and then select access groups, there is an option to present/unpresent physical disks, but it is inactive.

      Here is what the target(s) look like on the server. ovm-qa-repos3 is the new storage volume.

      Any help is appreciated.
