Dear all,
Is there anyway to know the size of TAPE DATA CART thru unix command ?

Thanks in advance.

me either.... I usually look at the tape, or in a remote site get the operator to read the tape label.

Hi William

This may seem a long way around the solution but if you have got no one at the remote site to tell you what type the tape is and have plenty of time and a little curiosity

First here's a link to the page

http://www.hp.com/products1/storage/products/media/tapebackup_media/tape_dds/

What you can do

After your full backup create an index of the tape

frecover -I /tmp/tapeindex

See what the last file is in the index

tail /tmp/tapeindex

Then , to make sure you have all the files on the index recover the last file.

cd /tmp

frecover -xXv -f /dev/rmt/0m -i /

upper case X will restore file to current dir

You can then add the totals of the files in the index

cat /tmp/tapeindex | awk 'BEGIN {total=0;} {total=total+$1;} END {print total,"\n";}'

Again would be grateful for more efficent solutions

Hi,

since HP-UX 11.00 the 'mt' command knows the option 'status' which can show you at least what kind of cartridge you have currently loaded:

einstein:/ # mt status
Drive: HP C1537A
Format: DDS-2 format
Status: [41112400] BOT online compression immediate-report-mode
File: 0
Block: 0
einstein:/ #

Then you can approx. check how many data will go onto the tape, but this depends from the kind of data and the possibility for the drive to compress it.
