Configuring the SP Switch Router Adapter
Installing the PCMCIA spinning disk
SP Switch Router Adapter Guide - 1.4 Update 2 October 22, 1999 2-7
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
1 Insert 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).
2 Log 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 --dup command 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.
3 Edit 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.
