Adding a drive that came from another HP Smart Array array to replace a failed drive
Posted on 2011-10-15
Have a Proliant ML350 G5 with embedded E200i Smart Array controller. Server has 3 72GB SAS drives configured in a RAID5. One drive failed and the array continues to run. I don't have a new, clean spare on the shelf and I don't want to wait until Tuesday to get a third drive back in this -- and Tuesday's probably the earliest I'm going to be able to get a new replacement. However, I have three drives of the same type that were pulled from another server. They weren't erased; they were working when pulled. I'd like to take one of those drives and plug it into the slot where my drive failed and rebuild the array NOW.
However, it seems like the last time I tried something like this, the array controller knew that drive I was trying to use was part of another array, wouldn't let me use it, and wouldn't let me erase or change it from inside HP Array COnfiguration Utility.
Can't afford to kill the array that's working... So, before I try to plug one in, I'm looking for guidance on whether or not I can expect this to work, or am I going to have find a way to erase that drive before attempting to use it.... Thanks.
