Hi Mangers,
I have a backup tape (Sony AIT 100Gb) on to which I have been
backing up the 3 advfs domains on our Compaq ALpha DC10. The
script I use is shown below.
My understanding of the vrestore process to access the files on the
2nd or 3rd saveset was as follows:
1) mt -f /dev/tape/tape0 rewind
2) vrestore -t -f /dev/tape/tape0 |wc -l # get no. files on f1st set
3) mt -f /dev/tape/tape0 fsf 10800 # Moves me to 2nd set
At this stage I get an I/O error (/dev/tape/tape0 fsf 10799 failed:
I/O error) and a mail report a from the privileged account.
What am I doing wrong? I have also tried using the STDOUT from
the vdump which tells me that the 1st saveset dumped 9569 files
and used "fsf 9569". Again same error.
I need to access the files on the 3rd saveset. I did use compression
on the first saveset but the system does report 10800 files in the
tape if I pipe the vrestore -t into wc -l.
Can anyone help?
thanx
Dp.
