There is NO migration path TO or FROM a nested RAID level (10, 50, 60) on any of the H-series PERC's, so going from RAID 1 to 10 isn't an option (without backup/replace/create/restore). The firmware release notes do not indicate much is added (although the "bug fixes" might be enough): - Added Support for >2.2TB SAS HDDs - Minor Bug Fixes I have not seen/heard of this issue (I do NOT have an H200), but it is possible that a firmware update can change the way it handles new drives, newly configured RAID arrays, or even how it presents these to the OS. Do you know if the technician checked to see if the original VD was marked as the boot VD?
Purchased the following server in November 2011 Poweredge  T110 II ManufDate: 10/24/2011   First Turned on: 11/6/2011RAM: 16GB (4x4) 1333mhz DualRanked UDIMMCPU: Xeon E3-1270 3.4Ghz, 8M cache, Turbo, Quadcore/8T (80W)Raid: Perc H200 AdapterDisk: 2x  600GB 15K RPM SA SCSI 6Gbps 3.5in - RAID 1 MirrorSBS 2011 Std x64  (runs on top of Win 2008R2) SBS 2011 installed without issue and the server has been running flawlessly since December 2011.  Backups occurring twice per day to a USB attached 1.5TB external drive and OS patches applied monthly without issue. Business needed more storage so wanted to add 2 more drives (same spec as purchased). I thought about trying to turn the RAID 1 pair into a RAID 10 set so as to keep the logical config simple (one big logical volume that now appears to be 1.2TB in size instead of 600GB) - however could not really get anybody to describe if this could be done in a non-destructive way that did not require the complete installation/restore of the system - so opted to just add the 2 new drives as an additional RAID 1 pair so as to not touch the stable, booting, running OS partition on the current RAID 1 pair. Contracted for Dell technician to come out to install the 2 new drives, being clear that the service was not complete until I had an additional RAID 1 pair appearing as a usable to the OS. Technician arrived, installed the drives, configured the new RAID pair in the H200 config utility, rebooted system and when OS started to load got a  blue screen BSOD. Technician then disconnected the newly attached drives (at the cable level) to see if the system would boot - BSOD again upon reboot (both of us now getting that "puckered" sensation if you know what I mean). Then went back into the raid config utility, deleted the new raid 1 volume (which by the way appeared ABOVE the existing one in the list - not very intuitive that the one just added is Volume 1 and the existing older one is Volume 2 in the utility). After triple checking that we had the right volume (it showed as 8% initialized versus the other which was complete, plus the drive port numbers matched) we DELETED the new volume (at this point I do not remember if we had reattached the cables to the drives to perform this action). Upon reboot the system restarted normally - we were all so relieved there was no more talk of further attempts at this time. Talking to Dell there appears to be an issue with the PERC H200 firmware or drivers. Didn't affect the initial config of a single RAID 1 pair, however caused issues when attempting to add another pair. Escalated support from Dell said that this has occurred a few times with Windows 2008 systems (which SBS 2011 is based upon). They recommended updating the firmware and drivers of the PERC H200 adapter. I turned to the technician and asked when we could schedule the firmware and driver updates and was told they would not do that (not sure I blame the poor guy, he was sweating bullets after the 2nd BSOD).  I explained that we contracted for installation services which included making sure the additional drive pair appeared as usable to the OS and he said I would need to speak to Dell about that. Wanted to post the info about the BSOD issues with the PERC H200 when adding drives on Win2008 (or SBS 2011). Waiting for Dell's response as to who is going to come onsite to finish the installation. Any info regarding whether the firmware/driver update will solve the issue and/or if I can reliably do a 2 drive RAID 1 to a 4 drive RAID 10 conversion without having to reinstall/restore the system would be appreciated.
