adding drive to HP 641 array controller
Posted on 2006-10-27
Hi all, I have an HP/compaq ml350 with a 641 array controller and have (3) 36.4gb u320 15k drives in a raid 5 array. I simply want to add another drive to the array. I slid in a new drive which says it is 36.3gb u320 15k. The array utility (ACU) does not show the "expand array" selection in the right side of the screen. It will only let me create a new array, which I prefer not to do which I did just to test the drive and it worked fine. I prefer to add it to the existing array.
I upgraded the firmware on the 641 and am using the latest ACU but still no luck. Could it be that because it shows as a 36.3 instead of 36.4 that it won't let me add it to the existing array?
