REALLY need help here....

So...... I just deleted my logical volume on my server..........

I alt tabbed into what I thought was my new array manager, turned out it was remote desktop of my old array. It only said 6 drives so I figured it finished the initialization improperly....... deleted it and figured I'd start over. Then I realized my mistake.........

This is NOT good at all

I know the data is still there, I really need to know if I can get it back

I'm going to start googling and calling people but I'm reaching out everywhere I can, still dumbfounded how stupid I am

LSI megaraid 9260-8i w/ 6x3tb drives in a dell poweredge r710

*edit: OS Windows Server 2012 R2

How important is this data, if its very important send it to a data recovery service.

If its less imporant and your want to take more risks, first thing to do is to make a image of every drive inthe array. Keep you from making it worse, and lets you do things like write new headers without risking losing more.

Also backups?

I managed to get it back thank god, now I've got a helluva headache, that's two day's in a row that two machines were almost destroyed.

I'm going to implement cold storage now, which I was planning on doing today anyways because it has all of my dad's computer image backups for years and my sister's backups like photo's, heck even my moms backups.

Just in case anyone is reading this in the future, I went into the MegaRAID Storage Manager, went to the physical tab and made sure they were all "good unconfigured" then went to the logical tab and right clicked the controller, first I checked for a foreign configuration to import but there were none, then I created a new virtual drive with all of the settings I had on it before including stripe size read/write policy and everything else then I made sure there was "no initialization" selected. Clicked create and that did it.

I don't know if having the same settings was important or not, stripe size probably is very important, but luckily the reason I had the Remote Desktop open with the megaraid open to begin with was to set my new array to the same settings as the old one.

I did this after googling and finding what other people did but there wasn't a lot of info on it that I could find, so I'll leave this up in case anyone does this in the future and finds this through google.
