Loading PT tapes on the Archive
Log into dolby.atnf.csiro.au as pulsar
> cd /pulsar/psr/raid
Check the number of files on the tape:
>tape_list <tape name> e.g. PT0270
If this produces an empty list, see RNM or GH.
Load the tape into the DELL DLT drive /dev/nst2.
Enter: initial (for example RNM) press 1 (in response to the next question) enter Y (for yes) next type the tape name (eg. PT0270)
After the tape is read:
> mt -f /dev/nst2 offl
If there is a problem you should go to the archive08 and remove the corrupted or unfinished file PT0270.tape.load by:
> cd /pulsar/archive08/PT_TAPES Note: Archive changed as archive07 is full
> rm -r PT0270.tape.load
Try using a cleaning tape in the drive, then start f-tapes again.
If everything worked and all the files are copied, go to:
> cd /pulsar/archive08/PT_TAPES
> mv PT0270.tape.load PT0270
> cd PT0270
> rm (files with 0 bytes)
Note: the destination directory is defined in the file /psr/raid/environment in:
set tapes = /pulsar/archive08/PT_TAPES
After tape is loaded you need to create a link from /pulsar/archive20 by the following steps:
> cd /pulsar/archive20/PT_TAPES (or cd $PTTAPES) Note: The main PT_TAPES archive has changed from archive00
> ln -s /pulsar/archive08/PT_TAPES/PT0270
> ll -rt
to check the link is working.
To check that all files are on the tape run:
> more /pulsar/archive08/PT_TAPES/PT0270.list or
Note that there are normally one or two spurious zero-length or bad files beyond the end of good data.
