Adding disks to an existing RAID-5 volume on a PE 2650 (PERC 3Di)

[craig.morris]

We have a PE2650 with 3x73GB drives in a hardware RAID-5 configuration.  As
a workaround for temporary storage issues we added 2 additional 73Gb drives
as a separate RAID-1 volume.  We would like to consolidate the 5 drives in a
single RAID-5 volume.  
 
Can we simply drop the RAID-1 and add the 2 disks to the existing RAID-5
_without_ dropping/recreating the RAID 5 volume?   The OpenManage
documentation indicates its possible but I want to hear from someone 'in the
field' as it where.
 
This post from the archives doesn't make me feel all warm and fuzzy:

Basically we just want grow the existing volume.  The server is an Oracle
host and we just want to drop/recreate the data partition without
re-installing the OS and Oracle.
 
We're currently running RH9 using ext3 with no volume management on the
Linux side.  
 

 

Thanks,
