[SunHELP] Cybernetics 8960 on an Ultra 30 with Sol 8

[Bret Adams]

Hey Everybody:

I am backing up some stuff over nfs to a cybernetics 8960 tape drive on an 
Ultra 30 running Solaris 8.  I raised my buffer size to 65536.  The minute 
I try to write to the tape on the cpio I get the following error in my 
messages file.

Jan 29 12:06:03 Error for Command: write       Error Level: Fatal

I have tried it with /dev/rmt/0 and /dev/rmt/0c  I am thinking my bufsize 
might be too big and I should back it down to 16384.  Has anyone seen this 
before?  Thanks.
