Add SATA Drives

I have 2 identical servers HP DL380 G5 that each have 2 - 146 GB SATA Drives.   We have removed them from production so I thought.....It ought to be easy to take 2 drives from one and add to the other to have 4 SATA Drives.  (Hot Plug Drives)

Hmmmmmmmmmmmmm.......Got green lights on them  but there has to be something else I need to do to get server to see the additional drive space.

Sort of lost on where to go and what to do...

Pretty new to this and learning more all the time.

Odds are you are running a smart array controller in your HP.

Run the Array configuration utility (via start smart or Windows program - free d/l from HP) and see what is up with the disks.  Also note that because it's a smart array controller (no pun intended), it may pick up that those two drives were previously mirrored and show a second array and logical drive on your controller.  Once you get it setup in the ACU scan for new hardware & go into the disk config in Windows.

I highly recommend backup your data before you start messing around in ACU, especially if you are not familiar with it :)

Also, keep the firmware at the same level.  My experience with HP and smart array controllers is you can kill your iops if you don't keep them on par.  And HP loves to do the firmware brush off when you have a failing HDD.

If these hot swap drives were set up in a RAID in the previous system, they will not show up in this system without deleting the partitions manually from Computer Management.

Go to compmgmt.msc, then Disk Management and see if they show up.  From there you should be able to format them so you have extra storage.

If you are trying to increase the size of the RAIDed partition on the system, this is not possible to add the drives without creating a new RAID array (which you do not want to do unless you want to wipe everything from your current system!)

You need to go into your RAID controller and add them to an existing array or create a new array with these 2 disks.  After that you can cread logical disks with them.

On HPs I believe it's one of three things you need to hit when you see it at the bios boot screen:
