I honestly don't remember the CLI syntax that is correct. Have you tried the OMSA GUI? It has a really nice little wizard that makes this a breeze.
And to answer your other question, yes I've successfully performed Online Capacity Expansion and RAID Level Migrations probably 5 or 6 dozen times with no data loss. -----Original Message----- From: linux-poweredge-bounces-Lists On Behalf Of Jeremy Smith Sent: Thursday, April 22, 2010 3:55 PM To: linux-poweredge-Lists Subject: Online Capacity Expansion (OCE) with Perc 6/i and omconfig I am interested in performing various Online Capacity Expansions (OCE) with a Perc 6/i and omconfig. 1. Converting a 5 drive RAID5 into a 6 drive RAID-5. 2. Converting a RAID-1 + Hot Spare to a RAID-5 According to Dell's PERC 6 documentation: http://support.dell.com/support/edocs/storage/RAID/PERC6/en/UG/HTML/chapterd.htm ...the PERC 6/i (among other controllers) is capable of this. And according to Dell's omconfig documentation on OSMA 6.2.0: http://support.dell.com/support/edocs/software/svradmin/6.2/en/CLI/HTML/storage.htm ...omconfig is also capable of this. My question is, has anyone ever actually successfully completed a RAID expansion like this by adding an additional disk? If so, how can I do this using omconfig? I tried converting the RAID-1 + Hot Spare to a RAID-5 with: RAID-1 across disks 0:0:0 and 0:0:1 Hot spare 0:0:2 [r...@server ~]# omconfig storage vdisk action=reconfigure \ controller=0 vdisk=0 raid=r5 pdisk=0:0:0,0:0:1,0:0:2 Cannot reconfigure to the given RAID level [r...@server ~]# omconfig storage pdisk action=assignglobalhotspare \ controller=0 pdisk=0:0:2 assign=no Operation disabled. Read, action=assignglobalhotspare assign=no .Refer to the documentation for more information. [r...@server ~]# omconfig storage pdisk action=offline controller=0 \ pdisk=0:0:2 Operation disabled. Read, action=offline .Refer to the documentation for more information. [r...@server ~]# omconfig storage pdisk action=remove controller=0 pdisk=0:0:2 Operation not supported. Read, action=remove Refer to the documentation for more information. What the heck do I need to do to accomplish this??? An error code I could reference in the documentation would be helpful, Dell! As for the RAID-5 to RAID-5 growing by 1 disk... I remember attempting this before with no success (similar problem as seen above). I have not attempted this again yet, but am planning to. Does the following look correct to accomplish that? Existing RAID-5 across 0:0:0 through 1:0:4 Fresh drive inserted as 1:0:5 (same capacity as other drives) [r...@myserver ~]# omreport storage pdisk controller=0 vdisk=0 | grep ^ID ID : 0:0:0 ID : 0:0:1 ID : 0:0:2 ID : 0:0:3 ID : 1:0:4 [r...@myserver ~]# omreport storage pdisk controller=0 | grep ^ID ID : 0:0:0 ID : 0:0:1 ID : 0:0:2 ID : 0:0:3 ID : 1:0:4 ID : 1:0:5 [r...@server ~]# omconfig storage vdisk action=reconfigure \ controller=0 vdisk=0 raid=r5 \ size=max \ pdisk=0:0:0,0:0:1,0:0:2,0:0:3,1:0:4,1:0:5 Any help would be greatly appreciated.
