Validate the Ethernet Management NEtwork
Bring up the Ethernet management network according to the plan that you developed in The Very First
Thing That You Do: Plan, page 43.
• Set up Ethernet IP addresses on all switches and hosts.
• Verify logical connectivity to all switches and hosts.
Set Up SE Tools on a Ethernet-attached Host
• Install expect software.
• Perl, TCL, Python.
• Collect tools from SVBU.
Perform a Switch Chassis Inspection
Scan the physical hosts and switches for the following indicators:
Look for box problems. Check management LEDs on each SFS chassis using the following commands:
• show diag fru error
• show diag post
Perform a Physical Inspection
(Optional) Record Leaf Switches and Hosts
• Create a NFS directory called leaves.
• For each leaf switch in your fabric, create a text file and assign the text file the same name as the
leaf switch.
• In the text file, list each host that connects to the leaf switch, listing one host per line.
Note Do not skip this task. The file that you create can be used during the troubleshooting process in
conjunction with the SE Tools (discussed in “Appendix B: SE Tools”).
Amber or red LEDs Consult your hardware documentation for potential causes of amber and red
LEDs and troubleshoot as specified.
Blinking green LEDs Blinking green LEDs typically indicate a bad physical link. Perform the
following steps:
Firmly secure cable on both ends? then what?
Blinking green HCA LED If a blinking green LED appears on an HCA, the HCA is probably bad and
should be replaced.
Blinking green Cisco 7008 or 7008p LED If a blinking green LED appears on a Cisco 7008(p), the Line Interface Module
(LIM) is probably bad and should be replaced.
