Yes.
I was on the wrong path because i thought that the default line
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
(the one in the example conf file) will check for tapealerts of the
drive, but what it really does is checking the autochanger for alerts.
And using tapealert on the autochanger device does the bad thing.
Nonetheless i did some more tests:
While storage daemon is running:
- Access to tapedrives with loaded tapes is not possible (Device or
resource busy)
- When accessing the only drive, which has no tape loaded (and was not
used since the last reload of the scsi driver) the command does not
return for minutes (so i canceled it)
- tapeinfo -f /dev/sg1 (which is the generic scsi device for nst0) does
work and give reasonable output.
- tapeinfo -f /dev/sg4 (which is the generic scsi device for nst3, the
on with no tape loaded) does work and give reasonable output.
After stopping the storage daemon:
- access to the drive with tape via /dev/nstx is possible an gives the
same output as /dev/sgx
tapeinfo -f /dev/sg5 (which is the autochanger) gives reasonable output
but does reset the scsi-controller (see message-log below)
