Check your st.conf file, it most likly has no config for the 9840 drives.
You shoudl be able to get htis from the STK web site. Also I think that the
STK NT driver should run at 256K. Label a tape on Unix, write some data,
then mount it with NT machine and scan the tape, if you get no errors you
are good to go.

Hey All,

 

Sun E450

Solaris 2.6

Solstice Backup 6.1.2

StorageTek 9310 Silo with 9940B drives

 

We just purchased a STK Silo with 9940B drives, and when I label a tape
I get the below messages.

 

01/28/03 09:34:23 nsrd: media notice: Volume "" on device
"/dev/rmt/18cbn": Block size is 80 bytes not 262144 bytes. Verify the
device configuration. Tape positioning by record is disabled.

01/28/03 09:34:23 nsrd: media warning: /dev/rmt/18cbn reading: Tape
label read: I/O error

01/28/03 09:34:25 nsrd: /dev/rmt/18cbn Label without mount operation in
progress

01/28/03 09:34:41 nsrd: media notice: Volume "Unknown" on device
"/dev/rmt/18cbn": Block size is 80 bytes not 262144 bytes. Verify the
device configuration. Tape positioning by record is disabled.

01/28/03 09:35:09 nsrd: /dev/rmt/18cbn Eject operation in progress

 

This was a brand new tape.  Is the block size after labeling now 256K or
80bytes?  Since it's been labeled will positioning by record be enabled?
When I relabel the tape I don't get the block size message, but I'm not
sure what size blocks the tape is currently using.

 

These drives will be used for DDS with a WIN2K system so I need to set a
block size.  Any suggestion for the best block size for compatibility
and performance?  I haven't been able to find much info on WIN2K max
block size, so if anyone knows where I can find that type of data I
would appreciate it.

 

I see similar questions answered in the archives, but I was wondering if
anyone had any more detail.

 

TIA,

 

Joel
