Hello all,
Perhaps someone on this list either knows details of drives and densities or knows where I can find those details.
I need to write data onto a tz89 that will in turn be readable on a tz88.
Now, I can write to the tz89 (using vdump) with any of the four devices: nrmt0h, nrmt0m, nrmt0l, and nrmt0a. Those all work fine.
However, I cannot read from the tz88 using tapes written with the nrmt0h or nrmt0m devices (I expected it to fail on the h device; I was not sure if the m device would work or not).
I am able to read tapes written using the "l" (lower case L) and the "a" devices. So, my question is this: how much data can I expect to write to a DLT IV in a tz89 using /dev/nrmt0l or /dev/nrmt0a?
Thanks in advance

Outlline of test methods (if the detail matters here):
on a tz89 using DLT IV and vdump, one fileset per tape cartridge
# vdump -0v -f /dev/nrmt0h
# vdump -0v -f /dev/nrmt0m
# vdump -0v -f /dev/nrmt0l
# vdump -0v -f /dev/nrmt0a
Take the tapes to the tz88 and read them one at a time, using
# vrestore -xv -f /dev/nrmt0h (used the h device each time for consistency)
The "h" and the "m" tapes caused vrestore to complain as follows:
vrestore: unable to use save-set: invalid or corrupt format
******* PROGRAM ABORTED *********
vrestore: unable to obtain fileset attributes
The "l" and the "a" devices happily restore files as described previously.
