Viewing LUN Information
The LUN Information tab contains information about the selected logical unit number (LUN). The type of
information that is displayed depends on the type of adapter you select, Fibre Channel or iSCSI.
Viewing Fibre Channel LUN Information
When you select a LUN associated with a Fibre Channel adapter from the discovery-tree, the LUN tab
displays information associated with that LUN.
To view the LUN information:
1.
Select Host, Fabric or Virtual Port view.
2.
From the discovery-tree, select a Fibre Channel port.
Note: LUNs that are associated with a manageable COMSTAR port do not appear in the
discovery-tree and cannot be configured using the OneCommand Manager
application or hbacmd utilities. To view the LUNs using the OneCommand Manager
application, you must view the COMSTAR port as a target.
Note: LUNs are discovered each time you click on the “+” symbol next to a target in the
discovery-tree. If an added LUN is not appearing below the target, click the “-” symbol
next to the target to collapse the LUN nodes and then click the “+” to expand the
LUNs again. The new LUN should be displayed.
Note: On Linux systems, to make LUNs that are newly added to a storage array appear on
the host, the following script must run from the command shell:
/usr/sbin/lpfc/lun_scan all
This is prevents you from having to reboot. If the host machine is rebooted after the
LUN is added to the target array, you do not need to run the script.
