LSI MegaRAID hangs during reboot

Hello Experts,
I have an old Gateway server with an LSI MegaRAID SATA 150-6D controller that will not boot.  All of the BIOS screens go by and the system hangs at the MegaRAID BIOS screen.  The system would normally launch Windows from there.  I can enter and modify the MegaRAID BIOS, but if I don't do that (i.e. I let the BIOS screen stay there), that is where the reboot process stops.  Any suggestions?  Thanks in advance for any help!

hi dlethe,
it was actually hanging at the point where the bios stuff is finished but before it tries to boot anything from cd or hard drive.  what ended up getting me further is temporarily disabling the megaraid bios (there is an option to do this within the megaraid bios configuration).  the option at the end of the megaraid bios setup now says 'press ctrl<m> to enable bios' (or something like that) rather than 'press ctrl<m> to enter bios', and if i don't do anything there it does proceed to boot from cd.  it still seems to recognize the raid array with the existing partitions that i had, so i am re-installing windows on c: (which is what i was trying to do in the first place).  i will keep you posted on what happens, thanks for your suggestions...

It sounds as tho the battery on the card has failed, and it is loosing its config during the reboot.

hello,
thanks for the reply.  unfortunately there is no battery on the megaraid card.  when i am able to enter the MegaRaid BIOS, i do see my one logical drive and the 5 physical drives, and everything looks fine.  when i exit the BIOS and reboot, the system hangs at the MegaRAID BIOS screen.

Try a windows recovery CD. If the CD sees the windows C:\ drive, then you know it is NOT the RAID controller .. the problem is a munged up windows distribution.   Conversely, if it doesn't see the RAID, then do the ALT-3 or whatever it is, and go to the 3ware BIOS and look for whatever is wrong.

But I do not think it lost the config. If it did, then the system would complain about no bootable disk.

The other alternative (gulp) is catastrophic drive failure.

Sounds like you got an irq issue.
Try moving the controller to a different slot.

through my own trial and error, i found that disabling the raid card bios allowed me to boot to a cd.  from this point i was able to reinstall the operating system, re-enable the raid card bios, and boot normally thereafter.
