Restore from tape OBDR not working

[Francesco Novi]

Restore does not work on server HP Proliant Gen8 with an external usb tape DAT 160 using OBDR.

The server has 1 internal disk :   /dev/cciss/c0d0
and looks at several hd of a disk-array (connected via fiber channel):
[2:0:0:0]    storage HP       HSV300           1100  -
[2:0:0:1]    disk    HP       HSV300           1100  /dev/sda
[2:0:0:2]    disk    HP       HSV300           1100  /dev/sdb
[2:0:0:3]    disk    HP       HSV300           1100  /dev/sdc
[2:0:0:4]    disk    HP       HSV300           1100  /dev/sdd
[2:0:1:0]    storage HP       HSV300           1100  -
[2:0:1:1]    disk    HP       HSV300           1100  /dev/sde
[2:0:1:2]    disk    HP       HSV300           1100  /dev/sdf
[2:0:1:3]    disk    HP       HSV300           1100  /dev/sdg
[2:0:1:4]    disk    HP       HSV300           1100  /dev/sdh

When trying to restore I get the error : /dev/nst0 failed to act as extended data disk for booting.

The backup has been done with the following command:

mondoarchive  -N -O -E "/var/lib/ntp/proc|/opt/dbbackup|/opt/mondo|/opt/iso|dev/sd*" -t -o -d /dev/st0 -T /opt/mondo/tmp -S /opt/mondo/scratch

Software installed:

mondo-3.0.2-1.sles11.x86_64.rpm
mindi-2.1.2-1.sles11.x86_64.rpm
buffer-1.19-4.sles11.x86_64.rpm
afio-2.5-1.sles11.x86_64.rpm

Please help me how to do the restore via tape.

Thanks

Another info that can help. On the machine there is installed xen, so the kernel is : 3.0.13-0.27-xen

On restore before getting the message: /dev/nst0 failed to act as extended data disk for booting.

I catch the message: mt: can't open /dev/nst0 device or address does not exist

Thanks

TH last error mentioned should be solved with rev [3115] which will be in mindi 2.1.6.

For the OBDR part, I'd need the mondorestore.log file generated at restore time, as well as the dmesg content in order to understand better why it's not working.

ALso please report what it gives with the latest versions (mondo 3.0.3 and mindi 2.1.5 just announced)

BTW for the OBDR part, you probably need to use the hpsa_obdr_mode program and add it to your installation so it can work as expected. Please Cf: #358

The latest test version of mindi at ​ftp://ftp.mondorescue.org/test/sles should solve your problem. Reopen if that doesn't solve your issue.
