usb drive prevents reboot of proliant

Hi

I have plugged a USB hard drive into an HP Proliant server for backup purposes

The trouble is that the server can't reboot i.e. if the USB drive is plugged in

I've looked into the cmos setup but nothing seems to help overcome this situation

I have noticed this with two different Proliant servers, one is a G2 running Debian Linux while the other, a G6, is running Windows 2008

any ideas ?

thanks

Get a cheap USB card and try that.

I've seen this issue many times.

Especially with Intel chipsets.

look in BIOS or setup for "USB emulation" or "boot from USB device" settings.

Hello, if you can go back into the bios, go to the boot tab and check the boot device order, for proliant I believe the IDE/ SatA try to boot first then the raid array, along those lines if the USB drive is listed, adjust the order so that the USB drive is last on the list.  I will look further to see if I can find exact steps if needed.

To clarify, I think in the proliant bios, it may say boot controller order, or USB control or something to that effect.

there are older systems that switch automatic to usb boot, if there is an USB device connected.
In this case, the only solution is to disconnect the drive for booting

Default settings on ProLiants are to boot from CD and USB before disks so as per above you need to change the boot order.

So far, based on my experience, I would have to agree with nobus

A G6 could hardly be described as an "older system".

then it's time to look if a bios upgrade addresses this problem
you verified the biuso battery?  it is a cr2032 and should have 3 V

This issue is known. And the funny thing is that such systems behave different with different usb drives. Means that some drives will not prevent the boot and some will do this.
Dig into BIOS settings. Try to disable USB boot and see if it works. Otherwise there is no other solution than disconnecting it before the boot. Upgrading BIOS normally won't work. Tested myself.

ProLiants even behave differently whether the key is in the back or the front (or internal) USB sockets, my diagnostic USB stick doesn't always boot using the front one.
