Zoning verification
The following sections describe how to verify the zoning for the VSM server and the DPM. Use these
sections to troubleshoot zoning issues.
VSM server zoning
To verify proper back-end zoning for the VSM server, open the VSM management interface. Go to
the Data Path Module and verify the number of back-end HBAs listed for each DPM. To check the
settings of the second VSM, failover the passive VSM. Check the back-end HBAs for that DPM on the
newly-active VSM.
DPM zoning
To verify proper zoning from the DPM side, extract the VSM Snap package (the file is named
save_state...tgz), and open the wwpn file located in the \proc\kahuna\fps\ folder. Use your
preferred editor application, such as Microsoft Notepad. Below is an example of the file content:
Prt WWPN T FC_ID S
=== ================ = ====== =
0 50001fe100002001 L 010000 U
0 20fd00606951a322 R fffc01 D
0 210000e08b813001 R 010d00 U
1 50001fe100002002 L 010100 U
This file shows the WWN of all ports known to the DPM. The “Prt” column shows the port number on
the DPM. The “WWPN” column shows the WWPN seen from this DPM port. This includes the ports
local to the system (designated with “L” in the third column), and all visible remote host/HBA or
target/disk ports (designated with “R” in the third column). The fourth column shows the Fibre Channel
ID. In the fifth column, an entry is marked “U” if it is both visible and currently logged in with the
DPM, while an entry marked “D” is either down or failed the login negotiation.
Use this file to verify that the host or target device HBA port is visible through the expected DPM port.
These entries can be correlated with the name server entries of the fabric switch to determine whether
cabling or the zoning configuration is correct.
For each DPM port, the first entry is the port itself (marked as ‘L’). For each even port (front-end port),
verify that the DPM can see the host HBAs zoned with this port. Similarly, for each odd port (back-end
port), verify that the DPM is connected to the VSM server and EVA or MSA ports as expected. Repeat
the process for all DPMs.
