The default block size for AIT-3 is 192KB not 64KB.

Make sure that you have four spaces between SONY and SDX in the
tape-config-list.
If you do a verbose reconfig reboot (boot -rv or reboot -- -rv), you'll
be
able to tell if it picked up your st.conf settings.
Finally, I believe AIT still uses 64K block size, not 192K, although
that
shouldn't matter.

Subject: Tape Positioning by Record is Disabled on AIT Drives??????
I have Networker Server 7.1 and a Spectra Logic treefrog
with dual Sony AIT-3 Drives running on a solaris 9 server.
My st.conf entry looks like this
tape-config-list=
"SONY SDX-700C", "SONY 8mm AIT-3 ", "SONY_AIT3";
SONY_AIT3=1,0x36,0,0xd679,1,0x00,0;
Legato says that the syntax of my st.conf is correct for the Sony AIT-3.
But whenever I try to restore I get this error.
"Cannot decode block. Verify the device configuration. Tape positioning
by
record is disabled."
Sometimes the recover works and sometimes the recover fails.
I called Legato and they said put these two environment variables in
place
so I put them in the .login file on the UNIX solaris 9 legato server
machine and rebooted
setenv NSR_DEV_BLOCK_SIZE_AIT_3 192
setenv NSR_DEV_TAPE_FILE_SIZE 10922
The problem is still occuring.
Anyone run into this or have similar drives?
The integrity of these backups and the recovery process
is in question.
