How do I  re-enable failed logical drive on DL380g3 with Smart Array 5i?

I was doing some testing on my ESXi Server, HP DL 380g3.  I removed one of my drives so it wouldn't accidentally get overwritten as it had a very important guest VM on it.  In this "testing" / "stupidly messing around" somehow all my "logical" drives were removed from the array.  I recreated the logical drive that my ESXi host was installed and reinstalled ESXi no problem.  Now the drive that was holding the guest VM reports that it is physically ok but the logical drive is failed.  When I boot up I come to the screen that asks if I want to press F1 to continue with logical drive disabled or press F2 re-initialize the drive but that data loss would likely occur.  I am very afraid that pressing F2 will cause enough damage that the guest VM will not run.  I have tried booting with Bart PE disk so that I could grab the data from the guest VM if possible, but it cannot see any of the SCSI drives.  Both drives (one for the ESXi host and one for the datastore that holds the VMs) are single drives, so the Controller says they are Raid 0.    Any help would really be appreciated!!

If you can delete the logical drive and array if you don't have any good data on current drives..  If you had been running raid0 it should pick up the array from the disk as the array signature is on both the hard drive and the controller.  If you had been running raid 1, raid 5 you may have an issue.  F2 in this case will most likely to delete the data, if you had the array and logical drive settings on the controller it would give you F2 to continue loading.

Thanks Paul.  I do not understand your first line.  The 2x "if" confuse me.  I do have good data on the drive.  It contains the guest VM.  Your comment about the array signature being on both the controller and the disk is helpful.  And as mentioned I was in fact running Raid 0.  So would you suggest to physically remove the drive, then delete the array in the controller, insert the drive again and see if the controller will pickup the signature from the drive?  Your comment about F2 likely deleting the data is also helpful.  I am going to avoid that.

Also do you think it matters that I have 2 additional arrays in the machine?  1 array is another raid 0 with a 72 Gig drive and another array is a Raid 5 with 3x 18 gig drives?  do you think this could have been caused by changing the order of the drives in the slots?

You're probably safe to press F2, but can't be sure without more info.

Please boot smartstart CD, go into diagnostics, array diagnostic utility and get a report and post this *as an attachment* to this thread. Please don't paste in as text as it's pretty long.

F2 should be ok, basically the data that was in the memory cache may be lost.  I can't gurantee this but I have done this for a large hospital and I was able to bring back the drive.  This was in a raid 5 set but the same principles should apply
