Collecting maintenance data
When director operational firmware detects a critical error or FRU
failure, the director automatically copies the contents of dynamic
random access memory (DRAM) to a dump area in FLASH memory
on the active CTP card, then initiates a failover to the operational
FRU. The director then transfers (through the Ethernet connection)
the captured dump file from FLASH memory to the management
server hard drive.
NOTE: An optional full-volatility feature is often required at military sites
that process classified data. If the feature is enabled through a product feature
enablement (PFE) key, a memory dump file (that possibly includes classified
Fibre Channel frames) is not included as part of the data collection
procedure.
Perform the maintenance data collection procedure after a firmware
fault is corrected or a failed FRU is replaced to capture the data for
analysis. Maintenance data includes the dump file, hardware log,
audit log, and an engineering log viewable only by support
personnel.
Collecting maintenance data (Element Management application)
To collect maintenance data (retrieve the dump file from the
management server hard drive) from the Element Manager
application:
1. At the Element Manager application, select Data Collection from
the Maintenance menu. The Save Data Collection dialog box
displays (
Figure 59 ).
