I just arrived at yet another one of those quaint points in my career where I bless the distance between me and the engineers at another company (in this case, Emulex). I would likely be in jail now if those turkeys were within an arm's reach. For the last week my service company and I have been trying to install a Fujitsu 2333 (330 Mb) disk drive on an Emulex SC7002 controller in a VAX 11/785. The problem was that the controller kept reporting an incorrect number of tracks for the drive. The drive is supposed to have 10 tracks but, under both Unix (specially modified) and the Emulex diagnostic program, the SC7002 reported 11 tracks. FINALLY, after much bullying, Emulex technical support examined the contents of the SC7002 configuration ROM and discovered that it is simply wrong. Soooo, if you are trying to use a Fujitsu 2333 and an Emulex SC7002, here is what you need to know: If you are installing the disk as an emulated RM05 (300 Mb) then you are fine. Everything works and you don't have to worry about a thing. This is SC7002 configuration 2B from table A-2 in the manual. If you are installing the disk as an expanded RM02 (330 Mb, 823 cylinders, 10 tracks, 64 sectors) then you probably need a new configuration ROM. The bad ROM number is 994F. I don't have the corrected one in hand yet but I suspect that it will be 994G. You certainly want a revision later than F. This is configuration 2C or 2D (both have the problem). There are two ways to tell if you are having this problem. The first is that Unix will find a screwy drive with 11 tracks. How that gets reported depends on your kernel. The second is to run the Emulex Massbus disk diagnostic, FMD000, test 6. If you have a bad ROM then you will see RM02 (823 Cylinders, 11 Tracks, 64 Sectors) I hope this saves someone else some grief. If the new ROM doesn't solve the problem you can expect either another message from me or a suicide note. :-) Be sure to stay up to date on net.unix-wizards and net.suicide. -- -- Art Zemon FileNet Corp. ...! {decvax, ihnp4, ucbvax} !trwrb!felix!zemon
