ISCSI Setup for Bacula

In My setup i have Dell TL-2000, so here below i am showing you some steps how to connect Bacula server with TL-2000

In Previous section you read, Bacula setup
http://raman-kumar.blogspot.com/2013/01/bacula-setup-by-rpm-in-centos-63.html

Now after that

Make sure you install iscsi-initiator  and MTX

The mtx command controls single or multi-drive SCSI media changers such as tape changers, autoloaders, tape libraries, or optical media

To Install, follow the following Steps.


#yum install mtx

Make Sure service always on once machine restarted as well.

[root@backup01 bacula]# chkconfig iscsi on


after that do some changes in conf file

#vi /etc/iscsi/iscsid.conf

node.startup = automatic
node.session.timeo.replacement_timeout = 144

Save the file and start the iscsi services.

then try to discover your tape drive. with following command.

iscsiadm –m discovery –t st -p

If everything goes ok then you can able to find this output


[root@backup01 bacula]# iscsiadm -m discovery -t st -p 192.168.200.177
Starting iscsid:                                           [  OK  ]

here is a trick then go under /dev/st or sg but you cannot see anything...after that restart services again  now you can see output like this.


[root@tbmh2ubackup01 bacula]# /etc/init.d/iscsi restart
Stopping iscsi:                                            [  OK  ]
Starting iscsi:                                            [  OK  ]

Now you can see lot of devise.

[root@tbmh2ubackup01 bacula]# ls /dev/st
st0     st0m    st1l    st2a    st3     st3m    stdout
st0a    st1     st1m    st2l    st3a    stderr
st0l    st1a    st2     st2m    st3l    stdin

More Info you can find by this way as well.

[root@backup01 bacula]# cat /proc/scsi/scsi

after that go to backup server and start teh srvices make it permanet as well

[root@backup01 bacula]# /etc/init.d/bacula-dir start

Starting bacula-dir:                                       [  OK  ]

[root@backup01 bacula]# chkconfig bacula-dir on

[root@backup01 bacula]# /etc/init.d/bacula-sd start

Starting bacula-sd:                                        [  OK  ]

[root@backup01 bacula]# chkconfig bacula-sd on

[root@backup01 bacula]# /etc/init.d/bacula-fd start

Starting bacula-fd:                                        [  OK  ]

[root@ubackup01 bacula]# chkconfig bacula-fd on

I Next Section i will share main configuration of dir.conf and sd.conf as well. 

Enjoy.

Note :- Keep it Simple
