That is not how Online Capacity Expansion works; it works by adding disks to the existing RAID, not replacing disks with larger ones.  For example, you could expand your 4x1TB RAID 5 to a 5-disk (or more) RAID 5 by adding and reconfiguring the array with additional disks 1TB or larger (although only 1TB would be used).  The only thing you can do after replacing/rebuilding disks individually is create a second array across the disks (called slicing); this will appear to the OS as a new/separate "disk".
Hello,  I have a PE R710 server with a PERC6/i controller.  I have a RAID 5 using 4 disks and now I need to expand the available space. I replaced the old 1 TB disks one by one and allowed the RAID to rebuild. I now have a RAID5 using 1TB of the 2 TB available. I read that to expand the RAID I could use OMSA webinterface or the omconfig command. In the web interface there is no "Reconfigure" available under System-->Storage-->PERC 6/i-->Virtual Disks-->RAID5. OMSA v7.1.0 I then turned to the omconfig and found that something like this should work: /opt/dell/srvadmin/bin/omconfig storage vdisk controller=0 vdisk=1 raid=r5 pdisk=0:0:2,0:0:3,1:0:4,1:0:5 action=reconfigure size=maxbut it results in:Invalid size parameter: reconfiguration size can not be specified by the user on this controller. Even though the PERC6/i supports Online Capacity Expansion according to the documentation.  I then tried to use "vdcapacityexpansion=yes sizeinpercent=100" even though it is specified that only the H700 and H800 controllers support this. Of course it failed but where do I go from here? I still have 4TB unused disk space. Would it be an idea to try to delete one disk and reinitialize it or is it at the vdisk level the change is needed ?  Regards Bo Riis
