Can I restart a machine while MegaRaid is reconstructing

OK, I hope this is a simple quick yes\no question.

I have an ESXi host with a RAID6 set consisting of 6 drives.   I have 2 more drives that I want to add to the set.    I have taken down the server and started the process to add one to the VD and the status is now in the reconstruction phase.   My question is whether it is safe to exit the LSI WebBIOS boot the server since the RAID6 set was fully intact at the time that I started.   At this rait, the process will take close to 10 hours and I really dont want the server down that long.   I am pretty sure that the answer is yes, but I cant afford to be wrong on this one.

Thanks

Should keep rebuilding - search for your particular model and the phrase "Auto-resume".

Keep the server down until the set had finished rebuilding, you don't want to risk loosing the complete set where you end up having to restore data from backup. This will take much longer.

Thanks Gerwin.   That was my gut also, and what I did.   But I have to do it again and was hoping for some more definitive answers to cut that time down.   But thank you for your input.
