Collecting

Maintenance Data

When firmware detects a critical error, the product automatically

copies the contents of dynamic random access memory (DRAM) to a

dump area in FLASH memory on the CTP card. Perform this

procedure after a firmware fault or FRU failure to capture data for

analysis by support personnel. Maintenance data includes the dump

file and engineering logs.

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 may include

classified Fibre Channel frames) is not included as part of the data collection

procedure.

To collect maintenance data use the following steps:

1. Select System Files from the Maintenance menu

(Maintenance>System Files). The System Files View appears

(Figure 4-5).
