Check the tape compatibility

[Pieter 't Hart]

please specify your info to the btcreate-program
the tape-device must ONLY contain the tape-devicename (tape0) NOT the full path (/dev/tape/tape0)

here is an commandline example

/usr/sys/bin/btcreate
-d /tmp
-a /bvh/etc/empty
-k /usr/sys/conf/TOMCAT-D
-m mfs
-s /usr/lib/sabt/etc/fslist
-t tape0_d1

the fslist file contains filesystems to include on the backup tape (/ /var /usr)
i also have the
/usr/lib/sabt/etc/custom_disklabel_file
which contains the disklabel for the bootdisk

The backup-device need not be compatible to CREATE the bootable tape but offcourse is does to use for restore.

Salem,
Looks like either your tape drive is not recognised or is incompatible. Please post the information requested by Pieter

Hi Salem,

This might be due to the grep command in the mktape script. In /usr/sys/bin/mktape script, if you search for "Device must be a tape", there is a grep command preceding this line.

echo ${TAPE_DEV} | grep _d >/dev/null

The grep command is looking for a tape similar to tape_d pattern.

If you modify this to grep tape >/dev/null, it might temporarily solve the problem. But the correct solution should be to check for the validity of the tape device using commands like mt.

Hope this helps.

Regards,
Sathya

Hi Salem,
i do not see output from the "file"-command

Sathya's answer suggest the script expects not only tape0 but tape0_d0 or tape0_d1 wich is related to density-settings used for the unit.
