Automating Netbackup Installation without user intervention in 7.X :
As we all know netbackup client installation can be performed using
1) Install_client_files
2 ) Or mounting the cdrom and performing installation using ./install .
The problem with above two methods is either we have to add client to policy or installation expects response constantly from user . I have a requirement to perform netbackup installation without user intervention .My requirement is to installation netbackup client software on 500 servers as part of baseline even before these are added any domain . I have achieved this by editing "install" script code providing by netbackup .
This helped in installing netbackup as part of base line along with OS .
Summary of tasks to do to automate netbackup installation
| S.no |
Entity to automate |
Action to be taken |
Script to Modify |
| 1 |
Is it Local installation |
Hardcode installation as local installation .
Are you installing to root environment?
|
.install |
| 2 |
Enter name of netbackup server |
Hardcode netbackup installation is client installation and give master server name inside the script |
client.inst |
| 3 |
Would you like to use XXX name as your client |
Hardcode client name inside the script as "hostname" (install) |
client.inst |
| 4 |
For 7.1.0.4 Which package would you like to install |
Hardcode client package to select in NB_update.install |
NB_upate.install |
| 5 |
Would like to install any other package |
Break the loop with the given code below to come out from 7.1.0.4 installation script |
NB_upate.install |

Hardcoding response for "Do you wish to continue ? "
Original source code New code
print_copyright print_copyright
${ECHO} " ${ECHO} "
Installing ${name_1} Installing ${name_1}

if confirm y "Do you wish to continue?" YES=1
if [ $YES ]
then then
install_product ${product_1} install_product ${product_1}
wrap_up $? wrap_up $?
else else
wrap_up 0 wrap_up 0
2 ) Hardcode Netbackup installation as client installation and give netbackup master name within the script
Line number : 552 , 754
Script : client.inst
if confirm y "Do you want to install the NetB | YES=1
if [ $YES ]
#if confirm y "Do you want to install the NetBackup clien

else else

fi fi
if [ " $ClientFILES" = " " ] ; then if [ " $ClientFILES" = " " ] ; then
exit exit
Hardcoding master server name
Orginal source code New code
master_ans=0 master_ans=0
while [ ${master_ans} -ne 1 ] while [ ${master_ans} -ne 1 ]
do do
Prompt " Prompt "
Enter the name of the NetBackup server : " Enter the name of the NetBackup server : "
read Server | #read Server
${ECHO} ${Server} >> | Server='XXXXXX'
This will be taken as master server name in bp.conf
3 ) Hardcoding cilent name inside the script
Line number : 777
Script ; client.inst
Goto client.inst file and edit it as follows : It would be inside /NBClients/catalog/anb . Install script internally calls this

Original source code New code
else else
if confirm y " YES='1'
Would you like to use \"${host}\" as the configured if [ $YES ]
name of the NetBackup client?" # if confirm y "
#Would you like to use \"${host}\" as the configured

then then
Client=${host} Client=${host}
else else
Prompt " Prompt "
Enter the name of this NetBackup client : " Enter the name of this NetBackup client : "
read Client read Client
${ECHO} ${Client} >> ${ECHO} ${Client} >>
fi fi
fi fi
else else
Configurations :
After installing netbackup check for exclude list .It is good to check exclude list and put the necessary default exclude list .
cp /netappshare/default_exclude_list /usr/openv/TI/bin
You can put the buffers also in the script .
Installing netbackup 7.1.0.4
4) Hardcoding client package to select in NB_update.install
Line : 163
Script : NB.update_install
return 0 return 0
fi fi
valid=0 valid=0
until [ ${valid} -ne 0 ] until [ ${valid} -ne 0 ]
do do
#read ans and if it is empty, initialize it w #read ans and if it is empty, initialize it w
read ans | ans='y'
> #read ans
: ${ans:=${1}} : ${ans:=${1}}
#write to the tracefile #write to the tracefile
${ECHO} ${ans} >> ${Trace_File} ${ECHO} ${ans} >> ${Trace_File}
case "${ans}" in case "${ans}" in
Y*|y*) Y*|y*)
valid=1 valid=1
return 0 ;; return 0 ;;
5 ) Break the loop to select another package after the installation using the following code
Script : NBU-update.install
Line : 429
Original code New code
VALUE="${PACK_NAME}" VALUE="${PACK_NAME}"
else else
VALUE="q" VALUE="q"
fi fi
${ECHO} "${VALUE}" ${ECHO} "${VALUE}"
else else
read VALUE #read VALUE
verify_upgrade=`cat /usr/openv/pack/pack.summary |grep -i
if [ $verify_upgrade -gt 0 ]
then
echo "INFO: Server has 7.1. 0.4 installed "
exit
fi
VALUE='NB_CLT_7.1.0.4'
fi fi
VALUE=${VALUE:=bad} VALUE=${VALUE:=bad}
Now your netbackup client installation is sucessful ..!
