LXPro netraid3 new disk
Hello,
We have an LX PRo with a net raid 3 (HP D4943A)controller. There are 3 drives fitted - 2 x elderly Quantum's and 1 x HP(Quantum under the label) 4.3G's on channel 1. Firmware on Netraid controller is current. Channel is configured as Ultra SCSI and disks as a Raid 5 array.
I have tried to add a new Quantum Altas V 9.1G as a hot standby on channel 1, but the Netraid Bios doesn't see it at all. I've also tried it alone on channel 2.
Why not? The drive should be backward compatible to Untra SCSI??
Thanks for any info
Regards
David Bennett

Re: LXPro netraid3 new disk
Hello,
The netRaid has Single Ended SCSI channels and the Quantum is a Low-voltage Differential device which should adapt itself to Single Ended if it detects the diff-sense line is pulled to less than 0.5V. Since this card is pre-LVDS, it might not comply 100% but unfortunately I do not know enough about NetRaid cards to verify this.
I would try another SE disk in the system.
regards,
Cal.

Re: LXPro netraid3 new disk
Thank you Cal,
The drive has a "force SE" jumper on it (Without a supplied link), so I'll try that.
If no joy, I'll have to get an SE drive.
