Steps to Perform Before Calling TAC
If no filename is specified, the file is created as volatile:show_tech_out.gz. The file should then
be copied from the switch using the procedure outlined in the “Copying Files to or from the Switch”
section on page A-3.
Step 2 If an error occurs in Fabric Manager, take a screen shot of the error. In Windows, press Alt+PrintScreen
to capture the active window, or press only PrintScreen to capture the entire desktop. Then paste this
into a new Microsoft Paint (or similar program) session and save the file.
Step 3 Capture the exact error codes you see in the message logs from either Fabric Manager or the CLI.
a. Select the Logs tab in the Map pane in Fabric Manager or choose Switches > Events to see the
recent list of messages generated.
b. Copy the error from the message log, which can be displayed using either the show logging log CLI
command or the show logging last number to view the last lines of the log.
Step 4 Answer the following questions before calling for technical support:
• On which switch, host bus adapter (HBA), or storage port is the problem occurring?
• Which Cisco SAN-OS software, driver versions, operating systems versions and storage device
firmware are in your fabric?
• What is the network topology? (In Fabric Manager, go to Tools > Show Tech Support and check
the Save Map check box.)
• Were any changes being made to the environment (zoning, adding modules, upgrades) prior to or at
the time of this event?
• Are there other similarly configured devices that could have this problem, but do not?
• Where was this problematic device connected (which MDS switch and interface)?
• When did this problem first occur?
• When did this problem last occur?
• How often does this problem occur?
• How many devices have this problem?
• Were any traces or debug output captured during the problem time? What troubleshooting steps have
you attempted? Which, if any, of the following tools were used?
– FC Analyzer, PAA-2, Ethereal, local or remote SPAN
– CLI debug commands
– FC traceroute, FC ping
– Fabric Manager or Device Manager tools
