Re: tar problem on tru64 5.1A
Do you have this I/O-error when tarring from any filesystem ?
If not do you have files in a particular filesystem larger than 2 GB ?
If files larger than 2GB, did you try the "E"(Extended Headers) commandswitch on tar.
Rgds,

Re: tar problem on tru64 5.1A
first in my old system it did not take large files. but now im trying small files like /etc/hosts.
i dont get any I/O error when moving from filesystem to filesystem.
my problem is with the tar.

Re: tar problem on tru64 5.1A
Let's start again...and provide some detail ..
whereis tar ; which tar ?
/sbin/tar or /usr/bin/tar ?
So "tar cvf /var/tmp/temp.tar /etc/hosts" works, but
"tar cvf /dev/tape/tape0 /etc/hosts" gives I/O-error
What is the syntax of the tar command that gives this I/O-error ?
What is the output of the command,
file /dev/ntape/tape0
etc....

Re: tar problem on tru64 5.1A
You can try differents block sizes to get the optimum performance. You should use vdump for backup.
