Retrieving the Code 43 Dump File
If an event code 43 was reported to the ADIC Management Console client, it is an indication that the SNC
4000 performed an error recovery operation and had to reset the FC interface to clear a lock-up condition.
For more information, see the
ADIC Management Console User’s Guide
.
This event is also recorded in the SNC 4000 event log along with the name of a file that was saved to the
flash file system. The file contains information about the state of the FC interface prior to the reset.Follow
these steps to retrieve the file.

Connect the service terminal to the service port.

Press
Enter
on the service terminal.
If the prompt is not displayed, go to
Service Port MAP
on page 60.

From the service terminal, navigate to the “DUMP” directory by entering the
cd
“
/ffs/dump
”
command
.
4
From the service terminal, enter the
ls
command to get a file listing for the directory.
There may be more than one file present if the error condition has occurred more than once.

Refer to the section
Saving a Configuration File
on page 17.
Substitute the name of the dump file and use that procedure to save the file to the service terminal.
Repeat this step if there is more than one file.
Save each file to the service terminal.

Send the file to [email protected] for analysis, attaching the dump file to the message.
Boot Mode Commands
diagBoot
This command is used only to transition an SNC 4000 from normal operations to the special diagnostic
mode.
•
The
diagBoot
command first ensures that the
/nvfs:mt
directory exists.
•
It copies the existing bootline to a file in the
/nvfs:mt
directory on the SNC 4000.
•
It installs a new bootline directing the SNC 4000 to boot using a special diagnostic startup script
/
ffs:mt/diagnstk.rc
.
•
It renames the persistent map file
config/device.map
as
config/device.bak
(a new file will
be generated after rebooting).
•
It issues a
reboot
command to put the changes into effect.
CAUTION
Dump file names end in
.dmp
and the files are automatically deleted
whenever you update the SNC 4000’s firmware.
CAUTION
All SCSI and FC cables must be disconnected before entering the
diagBoot
command.
