DAT-Tape backup on SME 5.5
« on: November 10, 2002, 08:14:12 PM »
Hello! I've got a tape drive today. it's a old one from Seagate technology.
It's a old DDS-2 drive with 4 gigs of data (uncompressed).
I now want to install it in my SME-server, now thw question is, can i just plug it in the machine with a SCSI-controller, and it's ready to use, or do i need to reinstall the whole SME-server, to get it to work ????

Regards, Per

Peter,

I am curious, how much data it will fit with your flexbackup job?
Since SME 5.1.2, I cannot get hardware compression on DAT (DDS-2) drives activated therefore about 4 GB is be the maximum here on 2 different servers.
It looks to me that the newer "mt" command versions since SME 5.0 have dropped the option for that so 1 server's back up (which was fine for more than 4 GB with SME 5.0) is not working any longer (since 5.1.2 upgrade).

Michael Doerner

Thaks !

hmm, but doesn't work for me.... i have a Symbios SCSI-controller and a Advansys controller i can use, not a Adaptec:-(

i wrote the different commandos, and when i write mt -f /dev/st0 status , the system just says: No such device !

Hmm, what can be wrong ??? where can i get a listing, of supported SCSI-controllers, that SME supports ??? and their name, i should refer to, using these commands....

hope you can help me, i'm new at this linux-stuff :-)

If you take a look in /lib/modules/2.2.19-7.0.8/scsi on your server, you'll see all the drivers.  Yours is probably sym53c8xx.o, or possibly 53c7,8xx.o.  Try "modprobe sym53c8xx.o" and see what happens.  If it seems to work, try the mt command again.
