SP Switch Router Adapter Guide - 1.4 Update 2
Configuring the SP Switch Router Adapter
Installing the PCMCIA spinning disk
Installing the PCMCIA spinning disk                   
Your system is shipped with a PCMCIA disk device that is required to collect the system log 
files. This disk can hold up to 520MB of data.      
You can install the disk any time after the SP Switch Router is powered on and is running. 
Logging is not enabled until you install the disk and complete this configuration procedure. 
Logged messages can be helpful while you are configuring media cards. 
The configuration is done only once to set up local logs and dumps, and is not affected by 
software updates or system reboots.
Note that the disk is used only for storage. You cannot boot the router from an external device.
Three logs provide specific information useful for monitoring and debugging SP Switch 
Router operations. If you are working with Customer Support, these are the three logs they will 
need to see: 
/var/log/gr.console  
  
  
/var/log/messages 
/var/log/gr.boot 
The 
/var/log
 directory contains other log files that collect low-level information useful 
primarily to system developers.  
The procedure formats and initializes an external device (
/dev/wd2a
), temporarily mounts it 
on 
/mnt
, creates subdirectories and symbolic links, and creates a permanent site file for storing 
the symbolic links.
Note that the iflash command can be used with a -f option that forces any data on the target 
device to be overwritten. When you use iflash without -f, you are informed if there is a file 
system already on the device and reminded that you must use the -f option to overwrite it. 
Because of its “force” capability, use the iflash -f command with caution.    
The 
/var/portcards
 directory only contains media card dump files. These include the 
dumps from media card panics and dumps created when automatic dumping is selected via the 
grreset -D command (media card dumps when it comes back up). The 
/var/crash
 directory 
contains dumps from BSD kernel crashes.                   
Managing PCMCIA slots 
Two commands enable remote management of PCMCIA slots. The csconfig slot_number 
command returns status while csconfig slot_number up and csconfig slot_number down mark 
the specified PCMCIA slot up or down, respectively.
