Re: Netraid 1si and wd 18gbdrives
As far as I know the Firmware of the HP NetRAID's controller (all of them) check if the disk drives have an HP firware too.

Re: Netraid 1si and wd 18gbdrives
The RAID controller itself should not be aware of SE or LVD SCSI, regardless of the branding of the firmware on the drives.
Another possible reason that the drives work in SE mode is that your cabling is faulty. In SE mode half of the wires are grounds, and it is possible that one or more of them are not making proper contact. This would become apparent only in LVD mode where each conductor must be functioning properly.

Re: Netraid 1si and wd 18gbdrives
Have you gotten the WD drives to work LVD Ultra-2 mode yet? HP NetServer Tech support suggests a drive firmware "difficulty". But WD is out of the SCSI business and Compaq, which used these drives doesn't have anything on it's website (that I can find) that addresses the problem.
WD tech support mentioned a rumor that insufficient terminator power could be at least part of the problem. Alas the drives don't provide term power; a way to check this would be to add an Ultra2 drive which DOES provide term power at the end of the SCSI channel. Also alas, I don't have one of these available to try.
My config is a 3si controller with a 68-pin WDE18030 in the common tray on channel 0 (it works fine), 3 SCA drives in the hot-swap cage that don't work LVD mode (array configures as RAID 5, on-line, but Win2K server cause drives to go to "FAIL" when it tries to write signature).
Finally, 3-17-2001, HP tech support suggested HP was considering a lab test of the WD drives to pin down our problem because they've been getting lots of calls - probably because egghead.com has auctioned maybe 1000 drives and lots of HP netservers.

Re: Netraid 1si and wd 18gbdrives
I would bet you've got the wrong terminators or perhaps the default jumper needs to be removed. Good luck!
