For the current version of Bacula, it's in the

Re: Examples of tape access

2019-01-22 Thread Harder, Pieter 
To add to that, that is basically what the guest support for z/VSE did. 
VGLIBSRV if I remember correctly. It wasn't there when I looked at it, so I had 
a little cooperation with I think Antoinette Kashner (I may have spelled her 
name wrong, or remembered incorrectly, anyway someone from Boeblingen) and 
wrote the CMS based additions for VSE class support myself. I don't remember 
who did DFSMS then in Endicott, but he accepted my changes into the IBM 
product. They were still there years later when my company dropped z/VSE.

best regards,

Necessary, but not sufficient.  (Why mtst instead of mt?) It's strange
that the DD book doesn't mention which of the tape operations are
supported for FICON.  In any case, you must be able to issue commands to
the library.  I don't see any support for that at all.

Linux is all about SCSI tape, not FICON, but if you're willing to do
manual mounts and category changes via the storage unit UI, you should be
good to go.

There is no non-CMS interface to DFSMS on VM.  You'll need a CMS

Necessary, but not sufficient.  (Why mtst instead of mt?) It's strange 
that the DD book doesn't mention which of the tape operations are 
supported for FICON.  In any case, you must be able to issue commands to 
the library.  I don't see any support for that at all.

Linux is all about SCSI tape, not FICON, but if you're willing to do 
manual mounts and category changes via the storage unit UI, you should be 
good to go.

>From CMS, as a DFSMSrms admin (untested):
1. DFSMSRM MOUNT SCRATCH SCRATCHx RDEV rdev VDEV 181 WAIT
2. TAPE FSF
3. Write left("VTS BULK VOLUME DATA REQUEST", 80) to 181
4. Write left("", 80) to 181
5. DFSMSRM DEMOUNT RDEV rdev WAIT TARGETCAT VOLSPECIFIC
6. DFSMSRM MOUNT VOLUME volid RDEV rdev WAIT
7. TAPE FSF
8. Start reading the data

In step 1, you can mount a specific volume if you want.  So if you have a 
IBM or CA tape manager software, you just ask it to mount a scratch tape 
from one of its managed scratch pools.

Unfortunately the Linux channel-attached tape driver doesn't appear to 
have any support for tape motion, e.g. FSF.  But without looking at source 
code, I don't know for sure or how much support there is for standard 
labels (moving past them).

You mount a newly inserted tape (one with no data) using standard labels. 
If positioned after TM (after label), write two 80-byte records as 
described in the published white paper on BVIR (google).  If at BOT, 
either FSF past the label or re-write the label, then TM, then the two 
80-byte records.

Then unmount the tape, change from INSERT to a private category.  Then 
mount by volser, skip over the tape label, and start reading.  BVIR data 
will be as described in the white paper.

Examples of tape access

2019-01-21 Thread Frank M. Ramaekers 
Does anyone have examples (bash script) of accessing tape units?  In my case it 
would be emulated 3490 (actual is TS7700).  I want to retrieve BVIR (Batch 
Volume Information Retrieval).  This involves writing a request to a new tape, 
closing, opening as input and reading the same tape back.
