Installing the PCMCIA spinning disk

SP Switch Router Adapter Guide - 1.4 Update 2

 

2-7

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

.

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). 

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

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. 

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.
