736.0. "20 MB then full on TZ875" by NNTPD::"[email protected]" (Irwin Nemetz) Tue Jun 03 1997 15:02

I am trying to run NSR 4.3 server on an Alpha 1000 NT 4.0 machine. The machine
has a TZ875
What is happening is that NSR is only putting about 20 MB on each tape. Here
are the messages:

Media Warning: \\.\Tape0 writing: end of media at file 2 record 116
Media Notice:  dlt tape mcsww2.alf.dec.com.001 on \\.\Tape0 is full
Media Notice:  dlt tape mcsww2.alf.dec.com.001 used 3.7 MB of 10 GB capacity.

The message is more or less the same for the other 4 tapes. 

Should I call field service ?

When was the last time you cleaned the drive?
Are there any problems noted in the event log
for the drive?  Are these new tapes?   You say
they put about 20MB per tape but give an example
of much less, if they were consistantly writing the
same amount, one should check that the volume
default capacity (in the device window when using
expert mode) hasn't been set.  Now, I can see that hasn't
been set for you... your values range from 3.7MB all
the way to 178MB (wow :).  Nothing looks out of
whack for the NSR setup on mccww2.

Please also read the daemon.log in the nsr\logs 
directory and from nsr\bin see if the drive reports
anything unusual when you do a 'mt -f \\.\Tape0 stat'
command.

thanks,

736.2Volume Default CapacityNQOS01::rdodial_port11.32.81.16.in-addr.arpa::CurleWed Jun 04 1997 09:378
Start the advanced NetWorker Administrator (-x) Edit the 
devices and look for the parameter: Volume Default Capacity.  I 
think by default it is set to 10GB.  You can change this 
setting to the tape capacity of your tape drive, but you will 
have to relabel all your tapes.  

You can look for ealier discussion on this for more details.

In the UNIX product, the volume default capacity is only used to 
compute the percent full for the volume.  NetWorker writes until 
it gets a write error, at which point it marks the tape full.  If 
your drive is dirty, it gets errors, causing less than the full 
tape from being used.

Re: .2

I did check this fellow's system out and noted so in .1.

Re: .3

Short tape is one instance where one can affect the amount
written to a tape on Digital UNIX with Volume default capacity.
One should be able to do something similar on NT with a
fake optical device.
