Netserver LH Pro

[Tyrone Miles]

When ever I boot up my server I get the error "Disk read error" All the drives light up and I see each drive post.

I have the Diag floppy and when I run the tests they seem to run fine. :( I am lost on what to do to fix this.

I have looked all over for some kind of raid tools that I can use to reconfigure the raid etc but I can not find any. :(

Thanks!

Tyrone,

The LH Pro does not have a built in NetRaid controller and if you are seeing each hard drive on POST you most likely are configured off the embedded SCSI. If you don't see a Ctrl-M and NetRaid bannering in POST then this is the case.


As for the Disk read error Boot into Ctrl-A and run a disk verify on each hard drive. Also try booting to each hard drive one by one and see if it is a single hard drive causing the problem.

Also Clear the CMOS with switch 3 and flash the bios for good house keeping. You can get the latest BIOS flash here: http://h20004.www2.hp.com/keeper_rnotes/bsdmatrix/matrix50454.html

It has a HPDA Mylex controler and I have 4 9.1 GB HP SCSI drives on it.. It was at firmware 2.47. I went to the Mylex Page and upgraded it to the Mylex driver DAC960PL version 2.73 (I want to run Linux on this server if I can)

Before I got a reply (And before I upgraded the firmware) I was able to get DOS to run on it and I even got 2000 AS to run on it.

Does anyone know if I have to change chips on that card to a Mylex chipset in order to be able to run Redhat? The is the real goal. :-)

Tyrone,

The HPDA Mylex controller is OEM'd from Mylex from HP so the chipset and fw is different from Mylex. You should go back to the last version of 2.47 from HP's site: http://h20004.www2.hp.com/keeper_rnotes/bsdmatrix/matrix62431.html

Also there is a 30 GB limit on the mylex controller for logical drive capacity so you'll be ok with 4x9gb hdds with 27gb total capacity but you won't be able to add any more capacity to that logical hdd. At the time the Mylex was made it wasn't possible to excede 30gb!

Ciao,
Greg

Tyrone,

I am not sure where you stand on this project now, but I recently received a quad LXPRo with the HP-Mylex adaptor. No matter what I did Redhat refused to see the adaptor. I took a chance and downloaded the firmware for the Mylex DAC960PL, which is this card and flashed the eeprom. The card now reports as true mylex and redhat runs fine.

You should not have replace any chips in the card. Just flash to a Mylex firmware
