Last week I wrote saying that my exabyte caused my 4/490 grief with the exabyte
hanging up. I think the nail has hit the camel on the head.
Steve Giuliano mailed me and said he had similar problems

I have'nt yet received the patch from SUN yet, but this is probably the

1) Bob Rogers <auspex!brogers> said that there was a known capability

that his drives were ok under 4.0.3 with the Delta driver, but switched to the sun driver for 4.1 and this brought problems. His proms were changed

2) Others told me to check cable lengths and/or scsi addresses or scsi

proper exabyte tapes).
4) Others pointed fingers at the scsi driver.
5) There were also complaints of a 1/2 inch drive on a 4/260 doing similar
6) Morry Katz <firstname.lastname@example.org> had similar problems with a 1/2 inch drive
