SP Switch Router dumps

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

System dumps

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.

Media card dumps

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 -Dcommand.

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

Use grdinfo to collect logs

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.
