Testing the Fibre Channel host adapter with FAStT MSJ
Note: Ensure that there is no adapter activity before running the test to avoid
losing data.
The Model 326 engine comes with FAStT MSJ for viewing the status of the Fibre
Channel connection as well as testing the adapter or cable. To use FAStT MSJ, first
start Terminal Services. For instructions on how to invoke Terminal Services, see
“Terminal Services and the IBM NAS Administration Console” on page 12.
You access FAStT MSJ by starting the IBM NAS Admin console, selecting NAS
Management
→
Storage
→
NAS Utilities
→
FAStT MSJ . Then, select Connect . A
diagnostic panel displays the following general information related to the Fibre
Channel adapter which can be useful if you need to place a support call:
v
Node name
v
Serial number (in hex)
v
Loop ID
v
BIOS version
v
Firmware version number
v
Device driver version number
v
PCI slot number
FAStT MSJ also provides the Model 326 engine’s world-wide name (WWN) as
detailed in “Managing Fibre Channel host bus adapters” on page 77.
