SP Switch Router Adapter Guide - 1.4 Update 2

Monitoring and Management Tools
SP Switch Router dumps

The SP Switch Router can be configured to send dumps to an external PCMCIA 520MB disk 
rather than to its own system memory. 

On the SP Switch Router, output from dumps, logs, and other system reporting functions refer 
to the SP Switch Router Adapter card as 

DEV1_v1

 or 

dev1

. Dumps are maintained in the 

directories 

/var/portcards

 and 

/var/crash

. 

Dumps are compressed to save space, and the compressed files are appended with 

.gz

. Media 

card dumps are stored in 

/var/portcards

 in a file named with the convention 

grdump.n.x.gz 

where 

n

 is the card slot number and 

x

 is the number of the saved dump, 1, 2, 3....    

Dumps provide specific information useful for monitoring and debugging the SP Switch 
Router and SP Switch Router Adapter card operations. If you are working with Customer 
Support, these are dumps they might need to see: 

–

bsdx.core

 - a kernel dump resulting from a system reset or panic, 

sent to

 /var/crash

  (x is number of the dump, 1, 2, 3...) 

–

grdump.n.x.gz

 

- a dump resulting from a media card reset or panic, 

sent to 

/var/portcards

  

If the SP Switch Router is reset or panics, a dump is saved in 

/var/crash

 under the naming 

convention 

bsdx.core

.

This dump is generally too large to send by e-mail. Customer Support will tell you how to send 
it to them.

The grsavecore command copies and formats information generated from a kernel panic as the 
data is written to standard output. The formatted data is written to 

grsavecore.out

 in the 

/var/crash

 directory.

The 

grdump

 program saves and manages media card dumps. As described in Chapter 2, you 

use the Dump or appropriate Card profile to specify the number of dumps to be saved in 
addition to the first dump of the day and the most current dump .  The default number is two 
per day for each media card. Dumps are collected from media cards when they panic or when 
they are reset by the system administrator using the grreset -D command. 

This dump is generally 4–8MB, and may possibly be e-mailed. Customer Support will tell you 
how to send it to them.

With a single command, grdinfo collects the  files in local 

/var/log/*

  (including 

compressed files)and compresses them in a log file. Refer to the grdinfo section in this chapter 
for more information.
