Hello DECLand,

	I have a question. I am having a problem with Ultrix 4.2 using a 4mm
DAT drive and a sequential tape stacker. The stacker runs fine in that anytime
I send a `mt -f /dev/rmt2h rewoffl' to the DAT it rewinds and ejects the tape
and the stacker puts the tape in the cassette pack and sequences to the next 
cassttte, loads it and the drive comes ready online.

	When I do a dump 0uf /dev/rmt2h /anyfilesystem where the total data
exceeds the capacity one data tape all that happens is a OPCOM message. Does
anyone out there in DECLand know of a parameter when using dump that will 
rewind and unload the tape like with a 9Track drive (TLZ07, TU81 etc..)?

	Also we are going to be using DEC's NSR (Legato Networker repackaged
by DEC) does anyone have experience knowing if NSR will accomplish the above
where a BACKUP exceeds tape capacity and spans multiple volumes?


Many Thanks in advance...

Jeff
