Configuring the SP Switch Router Adapter

Installing the PCMCIA spinning disk

Panic dumps sent to external flash device

The mountf and grdump commands enable the grdump program to work with an external flash device to capture media card dumps.

When a media card panics and there is a formatted external flash device plugged into a PCMCIA slot, a copy of the dump is automatically saved to the external flash in a directory called /var/portcards.

Installation steps

1Insert the PCMCIA disk into slot A on the SP Switch Router control board (the thickness of the 520MB device requires it be installed in slot A).

2Log in as root to the SP Switch Router, start the UNIX shell, and execute these commands from the shell:

prompt> sh

#cd /

#iflash -A

#grsnapshot --dup PA

#mountf -A -w -m /mnt

#mkdir /mnt/crash

#mkdir /mnt/portcards

#cd /var

#mv crash crash.orig

#mv portcards portcards.orig

#ln -s /var/log/portcards /var/portcards

#ln -s /var/log/crash /var/crash

#grsite --perm portcards crash

#cd /var/log

#pax -rw -pe -v . /mnt

#umountf -A

Note:

The grsnapshot --dupcommand places a copy of the internal flash boot and configuration files on the spinning disk. Customer Support may use these files to rebuild internal flash if a problem occurs.

3Edit the file /etc/fstab and add this line as shown in the excerpt below:

/dev/wd2a /var/log ufs rw 0 2 #PCMCIA slot A, use wd3a for B

#Filesystem mount table information. See the fstab(5) man page

#and the /etc/fstab.sample file for more information and examples.

#Each line is of the form:

#	device	mount_point	type	flags dump	fsck_pass
#

#Note that multiple flags (when used) are specified as a

#comma separated list without spaces.
