How Come it boots

Hi All,

 

I have a P4000, which has a broken raid set, three disks are failed. How come the OS on the raid set still boots. Surely it should report non-system disk

I guess, you have broken data raid set. System resides on third raid set (not shown on CMC), which in your case isn't broken. In case of P4500 G2 - it resides on mirrored disk pairs 1/3, 2/5 and 3/6

Re: How Come it boots

So are the mirrored pairs, 1/4, 2/5, 3,6.

 

Are these raid0 sets 1 and 4 stripped etc, then mirrored to each other, or in a raid 5 set.

 

Also I couldn't see this through the raid bios, should i be able to?

 

Sorry, but trying to get a better understanding of these.

 

Regards
