Re: [Networker] Block Size Questions

Funny that this question should arise when I just fought this myself at my
site. Someone went and changed my st.conf file on me and hosed it all.
The drive is not properly configured within Solaris and the
/kernel/drv/st.conf file...
I wish I had the actual entries needed to add into the file ofr you but you
should be able to get them from the manufacturer... on that note, I wish I
had a 9310 myself.... :P

Subject: [Networker] Block Size Questions
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
