TLZ07 and DDS-2 tape media?

» close window

The Question is:

 
Good Morning,
i have a TLZ07 and i use DDS2 Tapes, for what i know tlz07 should support dds2
 tapes.
The problem is that the dds2 tape seems not to be recognised and they are
 treated as DDS1.
I have tryed to use the following command, but it is steel seen as a dds1.
 
$init/media=compa/dens=dds2
$mount/foreign/cache=tape_data/media=compa/dens=dds2
$backup/log/image/rew/dens=dds2/media=compa
 
Any suggestion???
 
Thanks in advance,
Gianni.
 

The Answer is :

 
  The OpenVMS Wizard would expect a TLZ07 to recognize and process
  DDS-2 (DDS-2 120M and DDS-2 90M) media, as well as the older
  DSS-1 (DDS-1 90M and 60M) media.
 
  The media involved will generally have either a DDS or a DDS-2 logo.
  For what should be obvious reasons, your tapes should be DDS-2 logo
  90M or 120M tapes -- there has been both DDS-1 and DDS-2 90M media
  seen around, 120M is normally only DDS-2.
 
  Do not use DDS-2 media in a DDS-1 drive.  This can lead to problems
  with the media and the drive, as DDS-1 drives and DDS-2 media are
  not particularly compatible.  (DDS-2 media is thinner than DDS-1.)
 
  You can use DDS-1 media in a DDS-2 drive, and with recording formats
  compatible with DDS-1 drives.
 
  You may want to check for available OpenVMS ECO kits, as well, as
  there have been cases were displays were incorrect or compaction
  was not correctly enabled.
