[comp.os.vms] end-of-tape processing

CHRIS@ACRUX.USC.EDU.UUCP (06/12/87)

Does anyone other than me have problems with end-of-tape processing?
Imagine the following sequence:
	$ mount/init=cont mta0: foo
	$ copy/log t.tmp mta0:*.*	! very large file
	<reach end of tape, operator mounts next reel, gives REPLY/TO=n>
	$ dismount mta0:
	$ mount mta0: foo	! first tape again
	$ copy/log mta0:*.* *.*
	<tape spins merrily along, reaches the end, runs off the reel>

We're running VMS 4.4 with STC tridensity drives on Emulex controllers.

If you are using the tape in house or sending to a site running VMS
try this instead:

$ mount/for mta0:
$ backup/rewind/log t.tmp mta0:foo/save_set     ! you could have a /den=
$!                                                to 1600 or 6250.
$ dismount mta0:

  I experienced a problem restoring a file from a saveset which spanned
two reels.  Backup got to the end of the first reel and refused to
continue.  I could not get it to accept the second reel.  Naturally I
thought this was something I was doing wrong...
