Hi Team,

 

I am using IBM Tape 3584 L53 LTO4 for taking backup using bacula. OS is RHEL 6.4

 

I suspect this issue is somehow related to tape but hope someone will help me in resolving this  as my final goal is to setup bacula with it.

 

I have installaed lin_tape module But while using mtx-changer command I am not able to use changer device created by lin_tape instead I am able to use changer provided by sg driver.

 

 

[root@bacula bacula]# /usr/lib64/bacula/mtx-changer /dev/changer unload 37 /dev/lin_tape/IBMtape0 0

Unloading drive 0 into Storage Element 37...done

 

 

Where, /dev/changer is a device created with internal sg module .

 

Above command is successful executed and unloaded media from tape Drive 0 . but, I have a doubt it has not placed it on slot no 37 it is placing it on some other slot in a very fragmented manner. But tape always recognizing these fragmented slots location. I doubt this is because I am using sg device driver here(/dev/changer).

 

[root@bacula bacula]# /usr/lib64/bacula/mtx-changer /dev/lin_tape/IBMchanger0 unload 289 /dev/lin_tape/IBMtape1 1

/dev/lin_tape/IBMchanger0 is not an sg device, or old sg driver

 

Where as , in above command I have used changer device created with lin_tape module but system is not recognizing it as a proper sg device. I think problem related to slots will disappear using changer device created by lin_tape.

 

Please help in resolving the issue.

 

Regards,
