while writing to a tape device using tar I get an error message:
using 'tar czvf /dev/nsa0 /var/log/'
ppsrv3# tar (child): can't write to /dev/nsa0 : Invalid argument
My assumptions were
1) the dev/[n]sa0 device was the first scsi tape unit
2) that n meant non-rewinding
3) that I could write one tarball to the tape, then another, in
succession. Then each tarball would reside on the tape, one after the
other, and that I could untar them in succession as well.
So, what would be the cause of the "invalid arg" messeage above?
when attemptint to read the above tar file, with
tar tzvf /dev/nsa0
tar happily lists all files in the archive, but ends with:
gzip: stdin: unexpected end of file
tar: Unexpected EOF on archive file
I'm wondering if I have a blocking factor problem? This is a DAT/dds4
Any advice would be appreciated.
