ML150 g3 - USB Hard Drive Prevents SAS Boot.
Machine Spec.
ML150 G3.
HP 8 Internal Port SAS Host Bus Adapter.
Single 72GB SAS hard drive.
300GB Maxtor external USB drive.
Win2K3-SP1.
Original BIOS 2006.06.23
Current BIOS 2006.08.29 A
Background.
For years we have built stand alone HP servers (ML330, ML350 G3/G4, ML150 G2, ML110 G1/G2). They have all used external USB hard drives to perform unattended, overnight, scheduled backups, following a reboot (they are all Terminal Servers and so must be rebooted every 24hrs). The servers are in remote locations. Users are required to swap over the USB drives but otherwise do nothing. This has all worked fine for years тАУ the presence or absence of a USB drive making no difference to the boot order of the machines. As long as the users plug the USB drives in and power them on all is well. The ML150 G3 has changed all this!
Problem Statement.
With the USB drive plugged in and powered on тАУ and starting the machine тАУ the USB drive is тАЬseenтАЭ in the BIOS boot order as the FIRST device in the HARD DRIVE part of the boot device list. Under these circumstances the machine fails to boot. The USB drive is non bootable and for some reason the machine does not pick up the next device in the hard drive list тАУ e.g. the SAS hard drive. Instead the SAS drive is missed and the machine goes on to attempt the network boot тАУ which fails. If the USB drive is moved in the list to a position lower that the SAS drive the machine boots normally. However having made and saved that boot order change - if the machine is EVER booted without that same USB drive plugged in and turned on тАУ then that drive тАЬlooses itтАЩs place in the listтАЭ. Accordingly, subsequently - when ANY USB drive is plugged in and powered on тАУ and the machine is booted тАУ the USB drive is тАЬseenтАЭ at the top of the Hard Drive list and the machine fails to boot! This boot behaviour тАУ and my inability to control it in a consistent way тАУ makes the ML150 G3 unusable for us, given the user situation as described in Background above.
Additional Information.
When building the server I used a Win2k3 installation CD and a plug in USB floppy drive to load the SAS controller driver using the F6 method. That worked fine and normal with no problem at all. If I try to do the same thing with a USB drive plugged in and powered on and тАЬseenтАЭ at the top of the hard drive part of the boot list тАУ the Win2k3 setup cannot тАЬseeтАЭ the SAS hard drive! This may explain why the SAS drive is тАЬmissedтАЭ during the boot process тАУ where the USB drive is higher in the boot list. I have tried to find a BIOS option тАЬ Remove USB From Bootable Device ListтАЭ but have failed to find any such option.
Urgency.
I need help on this fast тАУ right now we have no product to sell. Surly I must have missed something?
Help Please.
Thanks and Regards,
Nick.
