Hi,
thank you for the advices. We have very similar configurations, and I'm
sure I'm not too far from the solution. I tried to use your settings in
the storage daemon config file, and the "mt" options as well, than I
didn't try so far.
But, as soon as I put those settings, I have another error
Hardware End of Medium = No # defaut is Yes
Fast Forward Space File = No # This line required if above
which is :
3-May 02:20 setmseblx0007-sd JobId 170: Error: Unable to position to end
of data on device "IBMLTO4" (/dev/nst0): ERR=dev.c:1354 ioctl MTFSF
error on "IBMLTO4" (/dev/nst0). ERR=Input/output error.
Strange that it works for you then ... I issued all the "mt" commands
you wrote. Tapeinfo gives me the samed infos as you have, but it's MTFSF
error or MTEOM ...
Regards
Yvan Broccard
