View Discovered Volumes
From the Volumes tab of the HPE Storage Connection Manager GUI you can:
- Select a volume without connections and create new initial connections
- Create an initial connection that is not a Favorite by deselecting the Favorite box
- Click Connect to create the optimal number of connections balanced across the host initiator ports
- Click Disconnect to disconnect a connected volume
- Check the Remove connect on startup box to remove to remove Favorite logins.
- View the properties of the connections to a connected target
Favorite refers to an iSCSI session that the host automatically attempts to reestablish when Windows reboots. When working with Favorites, keep the following in mind:
- If something changes on the host, network or array such that the Favorite iSCSI session cannot be established on reboot, the iSCSI session reports its state as 'reconnecting'. (The reconnecting state occurs during the time the host cannot ping the array discovery IP address.) The Connection Services ages and tries to remove reconnecting sessions gradually over time. Attempts to close reconnecting iSCSI sessions frequently fail. It may take several attempts to close a reconnecting session.
- If you attempt to close one or more Favorite connections in the reconnecting state, HPE Storage Connection Manager may show a negative number of connections. If this occurs, stop the Connection Services service while you are trying to close the connections. When the desired sessions are established, restart the Connection Services service.
- The iSCSI Initiator
(
iscsicpl.exe
) process may hang when attempting to close reconnecting iSCSI sessions. To exit this condition, open the Task Manager, select the Processes tab, highlight theiscsicpl.exe
process and click End Process. - Disabling host NICs used in Favorite login definitions sometimes causes the Favorite iSCSI login definitions to change. On reboot, these iSCSI sessions may not be able to be reestablished. Ensure that the Favorite iSCSI login definitions are correct after adding or removing host NICs, or enabling or disabling host NICs.
NOTE: The connection manager does not
display Volume Scoped Target (VST) snapshot volumes by design. For Group Scoped
Target (GST), snapshot LUNs are no different that regular data LUNs. They appear as
child LUNs under the GST.
NOTE: A deep
discovery operation may take anywhere from several seconds to several
minutes depending on the I/O load, the network bandwidth utilization, and the number
of active and reconnecting connections.
