3.1.2 Matrix Server Administration Guide

Appendix B: Error and Log File Messages 282

The following utility is useful for determining whether a matrix node can

communicate with the FibreChannel switch. The command displays the

name service entries of the WWPN and the Fabric IDs of the switch. It

may take approximately five or six seconds for the output to be

displayed.

PSANinfo -c <snmp community string> <IP address of FC switch>

Default VSAN Is Disabled on Cisco MDS FC Switch

If you are using a Cisco MDS FibreChannel switch with firmware version

2.1 or later, you may see the alerts such as the following on the PolyServe

Management Console:

FenceAgent <switch_name>: no response to queries from <node_name>

You might also see additional logging in psSAN.log:

Transient Error: fabric.c@1119 FABRIC Switch

<switch_name> SNMP request 160, status 6

These messages occur because the default VSAN (VSAN 1) is disabled,

which causes fcFeFabricName (FA-MIB defined) to be unassigned (all

zeros). Currently Matrix Server uses the OID assignment for

fcFeFabricName to probe connected FC switches and will return the

above error messages if it is unable to determine a value for

fcFeFabricName.

These alerts can be quiesed by enabling the default VSAN (VSAN 1).
