We have a number of ML350s and do our backups to disk. We have never had a problem until we upgraded the 500 GB Iomega external USB drives to 1 TB ones. At every server reboot (after updates for example) the server tries to boot from the external USB drive.
We have tried everything I can see in the BIOS. The boot order is for the RAID controller first, and boot drive order is C: then DROM then NIC then USB. The USB drive is recognized in the BIOS as C:, and I think this may we were the problem arises, but I see no way of changing this in the BIOS level the Iomega is listed as H: once the OS starts up.
The odd thing is that its not consistent, we have 12 identical servers with the same BIOS setups and Iomega drives, some will start up others not (or maybe on the third or fourth reboot). If I set the boot order to be CDROM then C:, then its guaranteed they will attempt to boot only from the Iomega.
We have the latest version of the BIOS on all computers. Any suggestions welcome!
