I was able to reproduce this between a Sun and DS3100 here. Your rdump parameters are asking /etc/rmt on hermes - which is the program that actually does tape I/O when you run rdump - to write 64512-byte buffers. From a quick look at the Ultrix source, it appears that Ultrix /etc/rmt has a 10K limit on the size of a block you can write. I suggest obtaining the BSD version of rmt (which you can ftp from uunet, it's in bsd-sources/usr.sbin/rmt) and installing it instead of /etc/rmt. The BSD version dynamically allocates buffers and can read/write whatever large block size you want. Installing the bsd rmt here fixed the problem. hope this helps. steve -- Steve Hayman Workstation Manager Computer Science Department Indiana U. sahayman@iuvax.cs.indiana.edu (812) 855-6984 NeXT Mail: sahayman@spurge.bloomington.in.us
