HP DC SAN Backbone Director Switch Hardware Reference Guide (5697-2158, August 2012)

• A surface to place the old chassis on, such as a second lift or the pallet originally provided
with the old chassis
• #2 Phillips screwdriver
Verifying the need to replace the chassis
To verify that it is necessary to replace the chassis, ensure that the components are firmly seated,
troubleshoot the chassis following the list below, and contact your support provider with any
remaining questions about whether the chassis should be replaced.
Any of the following events can indicate the need to replace the chassis:
• Visible mechanical damage to the chassis, including damage to sheet metal or card guides
that prevents correct installation of a blade.
• Bent or damaged connectors on the backplane (the surface inside the chassis to which the
blades connect).
• One or more components (such as a power supply, blower assembly, port blade, control
processor blade (CP8), core switch blade (CR8), or WWN card) do not function properly
even after the component is replaced.
• The psShow or fanShow commands continue to show a faulty component even though the
component has been replaced.
• The slotShow command continues to show a faulty control processor (CP8), core switch
(CR8), or port blade even though the blade has been replaced.
Recording critical DC SAN Director and SAN information
All commands for recording critical DC SAN Director and SAN information must be entered from
a CLI session (Telnet or serial) to the active CP blade unless otherwise indicated. For detailed
information about Fabric OS commands, see the Fabric OS Reference Manual. Use the checklist
in Table 18 (page 83) to record the critical information.
NOTE: Run supportShow to display important configuration and SAN information.
Table 18 (page 83) lists the information generated by this command. Record the location of the
.txt files, which are created in this procedure and are not displayed in the supportShow output.
