Collecting Maintenance Data

When the switch operational firmware detects a critical error or FRU failure, the

switch 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 switch then transfers (through the Ethernet

connection) the captured dump file from FLASH memory to the HAFM appliance

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 by third-level

support personnel. Maintenance data includes the dump file, Hardware Log, Audit

Log, and an engineering log viewable only by support personnel. To collect

maintenance data:

1. Open the HAFM application. The View All - HAFM 8 main window displays.

2. Double-click the icon representing the switch for which the data collection

procedure will be performed. The Hardware View for the selected switch

displays.

3. Choose Maintenance > Data Collection. The Save Data Collection dialog

box displays, as shown in Figure 42.
