How do I expand RAID 10 on Dell PERC 4e/DI

I have a Dell PE 2800 with PERC 4e/DI and MS Win Server 2003 Standard 32 bit.  The PERC presently has 4 73gb SCSI drives running RAID 10.  I have added 4 more 73gb drives to the system and have tried to reconfigure the RAID.  However, in OMSA the reconfigure choice deos not show up (v 6.3 OMSA).  I have installed the latest firmware for the PERC and have the latest driver from Dell (6.46 I think).  According to all I have read, I should be able to do this but can find no way.  Even in the BIOS utility, the reconstruct shows nothing to reconstruct.

The firmware will block expansion if any members are currently undergoing any background jobs (so make sure nothing else is going on). Also if any disks are owned by the peer adapter in a cluster controller.   Hopefully it is something simple like that.   But, the specs clearly show that an 8-drive RAID10 is supported.  

You could, just to make sure it works, build a new array with the 4 drives.  Actually unless you are doing some extremely large block I/O, then this will provide better overall performance.   In a Win2K3 environment, I can't imagine any upside on a single RAID10 vs 2 x RAID10.   SQL server, for example, uses native 64KB i/O block size.  So expanding into a single RAID10 will most likely cause a performance hit anyway.

I have created a RAID 5 from the 4 new 73gb drives and the choice to reconfigure shows up for that array, but still not for the RAID 10.  There is no cluster and there are no background jobs.  I think I will just copy the data partition from RAID 10 to the new RAID 5 and expand the OS partition on the RAID 10 to give me the space I need.  I've been working on this for two days now and not had much luck.

Fair enough.  The documentation says this is supposed to work, so maybe it is a good old fashioned bug.  Are you sure you upgraded the controller firmware, not the BIOS of the PC?  Read release notes carefully.  The BIOS of motherboard is not the same as the PERC firmware.

No, I did upgrade the controller firmware.  That was the only way I could install 6.3 OMSA.  I really appreciate all you have suggested and I am giving you the points.  Thanks very much for you help.  I have copied the partition to the RAID 5, renamed the new partition to the old drive letter and resized the OS partition and everything appears to be working very well.  Thanks again.
