Depends on your OS though.<BR /><BR /><BR />Once complete, there may be other steps necessary to complete the process.<BR /><BR /><BR />What OS are you running?<BR /><BR /><BR />Steven Thu, 03 May 2007 09:26:37 GMT Steven Clementi 2007-05-03T09:26:37Z https://community.hpe.com/t5/disk-enclosures/raid-5/m-p/3993140#M23702 Just a question. I have on a hp proliant 380 2 HD in raid1 and 3 HD in raid5.<BR />I have to add 1 HD on raid5. Is it possible add the hard disk without redo the array or is necessary to re-create the array?<BR /><BR />Thanks<BR />Luigi<BR /><BR /> Thu, 03 May 2007 07:38:37 GMT https://community.hpe.com/t5/disk-enclosures/raid-5/m-p/3993140#M23702 Luigi Savoldelli 2007-05-03T07:38:37Z https://community.hpe.com/t5/disk-enclosures/raid-5/m-p/3993141#M23703 Luigi:<BR /><BR />You should be able to hot add the drive to the server, open up ACU... add it to the array ("EXPAND" array) that is handling the RAID5 logical disk, then (once the operation is complete) "extend" your logical drive using the newly available space.
