Boot; Interpreting Post Results; Switch; Results - HP Brocade 4Gb SAN Installation Manual

Boot

Boot completes in approximately three minutes if POST is run. Boot includes the following
tasks after POST is complete:
• Universal port configuration is performed.
• Links are initialized.
• Fabric is analyzed, and if any ports are connected to other switches, the 4Gb SAN Switch
participates in a fabric configuration.
• The 4Gb SAN Switch obtains a domain ID and assigns port addresses.
• Unicast routing tables are constructed.
• Normal port operation is enabled.

Interpreting POST results

POST is a system check that is performed each time the switch is powered on, rebooted, or
reset. During POST, the LEDs flash different colors. Any errors that occur during POST are
listed in the error log.
To determine whether POST completed successfully and whether any errors were detected:
1. Verify that the 4Gb SAN Switch LEDs indicate all components are healthy. See
page 41 for description and interpretation of LED patterns. If one or more LEDs do not
display a healthy state, verify that the LEDs on the switch are not set to "beacon" using the
switchshow command.
2. Verify that the 4Gb SAN Switch prompt appears on the terminal of a computer
workstation connected to the switch. If there is no switch prompt when POST completes,
press Enter. If the switch prompt still does not appear, try opening another telnet session or
another management tool. If this is not successful, the 4Gb SAN Switch did not
successfully complete POST; contact your switch supplier for repair.
3. Review the switch system log for errors. Any errors detected during POST are written to the
system log, accessible through the errshow command.
For information about all referenced commands and accessing the error log, refer to the HP
StorageWorks Fabric OS 5.0 procedures user guide. For information about error messages,
refer to the HP StorageWorks Fabric OS 5.0 diagnostic and system error messages reference
manual.
