Customizing JET Boot Image Recovery with TSM

This section describes the steps necessary to include a TSM client as part of the Boot image to enable root filesystem recovery.

1.	TSM Client
On a working system, tar up the /opt/tivoli directory. On the JET server un-tar archive to the /jumpstart/solaris/sol9/Solaris_9/Tools/Boot/opt directory.

Certain tasks are required to be performed to allow editing of config files. Change directory to /jumpstart/solaris/sol9/Solaris_9/Tools/Boot/opt/tivoli/tsm/client/ba/bin and rename dsm.sys and dsm.opt to dsm.sys.example and dsm.opt.example. create symbolic links for dsm.opt and dsm.sys to /tmp.

2.	JET Boot image
Two files require editing in the /jumpstart/solaris/sol9/Solaris_9/Tools/Boot/sbin directory. 
i.	rcS

Add the following highlighted entry ;-
set -- ""
set -- ‘/sbin/getbootargs 2>/dev/null‘
if [ $# -gt 0 ] ; then
while [ $# -gt 0 ] ; do
case $1 in
FD=*)
# at end of script, save root dev in /tmp/.preinstall
# this is an unambiguous indication of stub boot
FJS_BOOT="yes"
From=‘(IFS="="; set -- $1; echo "$2 $3 $4 $5" )‘
break
;;
browser)
cat < /dev/null > /tmp/.install_boot
cat < /dev/null > /tmp/.smi_boot
shift
;;
recover)
cat < /dev/null > /tmp/._recover_startup
shift
;;
install)
INSTALL_BOOT="yes"
cat < /dev/null > /tmp/.install_boot
shift
dhcp)
TRY_DHCP="yes"
shift
;;



ii.	Add the following highlighted entry to run_install;-

NOWIN_FILE=/tmp/.nowin
date >> /tmp/$LOG_FILE
TMP_ROOT_WEBSTART=/tmp/root/webstart
VOLMGT=volmgt
RECOVER=/tmp/._recover_startup
NAME=`uname -n`

if [ -f ${RECOVER} ];then
        echo "You are now entering the recovery mode..."
        echo "Adding TSM Backup Servers to the hosts file"
        echo "10.14.121.79 backup_server " >> /etc/hosts
        echo "10.14.113.114 backup_server2 " >> /etc/hosts
        echo "Creating example dsm.opt and dsm.sys files"
        cp /opt/tivoli/tsm/client/ba/bin/dsm.opt.example /tmp/dsm.opt
        cat /opt/tivoli/tsm/client/ba/bin/dsm.sys.example|sed s/lnjps1m/${NAME}/g > /tmp/dsm.sys
        touch /tmp/inclexcl.lst
        chmod 777 /tmp/inclexcl.lst
        echo ""
        echo ""
        echo ""
        echo "In order to use TSM to recover this system, you must first"
        echo "edit the dsm.sys and possibly the dsm.opt files. These are "
        echo "located in /tmp. Set your DISPLAY variable. "
        echo "Set LD_LIBRARY_PATH=/usr/lib:/usr/share/lib:/usr/dt/lib"
        echo "Set DSM_LOG=/tmp"
        echo "Run /opt/tivoli/tsm/client/ba/bin/dsm"
        exec ksh -o vi -a
        shift
fi

3.	Booting the Client System
On the client system from the boot prompt;-

{0} ok boot net - recover  
Rebooting with command: boot net - recover                            
Boot device: /pci@1f,4000/network@1,1  File and args: - recover

Adding TSM Backup Servers to the hosts file
Creating example dsm.opt and dsm.sys files



In order to use TSM to recover this system, you must first
edit the dsm.sys and possibly the dsm.opt files. These are 
located in /tmp. Set your DISPLAY variable. 
Set LD_LIBRARY_PATH=/usr/lib:/usr/share/lib:/usr/dt/lib
Set DSM_LOG=/tmp
Run /opt/tivoli/tsm/client/ba/bin/dsm


Follow the instructions given and the TSM GUI will be displayed which will enable a restore of  the root filesystem.
