Thank you. I'm doing a full backup now and will conduct the full test of the disaster recovery plan tomorrow. Thanks again. ... View more

Smart Array 641

We have 2 identical HP ML350 G4 servers with 641 Smart Array Controllers... the only difference between the two machines is the configuration of the Array's. One is setup as Mirrored four 73 gig drives (2 logicals) and the other is setup as RAID 5 with five 73 gig drives (one logical). The RAID 5 server is a fully functioning web server with web sites and data that we must retain. The RAID 5 server also performs double duty as a hardware backup for the mirrored server in the event of a hardware failure... in other words, protection from a total loss of the mirrored server (our Domain Controller) by temporarily sacrificing the web server, and using it as the Domain Controller. bTw... it's SBS 2003. We would like to test our disaster recovery procedure by removing the 5 drives from the RAID 5 server and replacing them with 4 new 73 gig drives and then performing a bare metal restore of the mirrored server to what was the RAID 5 server. So far no problem, we are certain we could do that easily (famous last words). The question is... "what happens after the test when we return the five 73 gig drives to their original server (the web server) and then attempt a boot? The bare metal restore would have necessitated our changing the setup of the 641 from the original RAID 5 to mirrored. Will the controller need to be reconfigured back to RAID 5 prior to attempting a boot or will the controller be smart enough to recognize the old RAID 5 configuration (from the disks?) and reconfigure itself accordingly? The worst case scenario says the 641 will reset and wipe the 5 drives containing our web sites clean, and we can't let that happen. Any ideas/direction is greatly appreciated. Thanks ... View more

This is not my only active directory server... it is a member server in a Microsoft Small Business Server network. Being that the member server is dual-boot do you still think there is a risk of Active Directory problems? I'm not sure. If it happens again I'll pay more attention to what file it says is corrupted but I am certain it wasn't NTLDR. I have a full backup using the built-in Windows 2008 Server Backup facility. Can you think of any reason why I couldn't run the "repair" function? What "drivers" would you assume it is asking for? I assumed it needed the Smart Array 641 drivers but it wouldn't accept the same drivers I used that worked fine when I originally installed Windows 2003 Server. Thanks for your input. ... View more

Strange boot problem

I'll be as brief as possible. ML350 G4 Server with a Smart Array 641, 3 drives setup as 3 logical... The server is a few years old. I Was running Microsoft 2000 Server until 6 months ago when I upgraded to Windows 2008 Server Standard. I left the original OS in place and setup a dual boot. During the original install of 2008 I needed to use the F6 option to install drivers for the Array as I didn't want to use Smart Start and risk data loss. The install of 2008 went fine and all has been fine ever since. Just this morning I needed to re-boot the server and it wouldn't boot. It gave me a message about missing file or corrupt file and said to use the repair my computer option by booting from the 2008 install CD and selecting "repair". I tried doing that but it prompted me for the driver (I assume it needed the Disk driver again) so I used the same diskette (holy crap) that I had used when I installed the OS (using F6) but this time it told me that the drivers weren't found. I tried several variations of drivers... some freshly downloaded and some from the Smart Start CD but nothing would work. Desperation set in as I had an entire company sitting on its hands waiting for me to bring the server up so I reluctantly decided to boot to the original OS (Windows 2000) and let them work using the old OS for today and I would fix the server over the weekend. No joy... many messages about broken trusts etc so I abandoned that idea and went back to trying to get the "repair my computer" function to work. Again... no joy. I decided to try the old OS again and rebooted the machine (for about the 10th time today) but prior to the OS selection screen being displayed I was called away and by the time I got back the machine had booted to the new OS (Win 2008 server is the default) and everything was working fine. Good grief! I can't just shrug my shoulders and say "Oh well". I need to know why the machine decided to load properly this time, after repeated attempts earlier had all failed. Is it possible that my booting into the old OS somehow restored some files needed for boot? I'm at a loss to explain. Any ideas? Thanks ... View more
