You will need to make sure that the new disk drives that are being added to lun0 are the same size as the disk drives that are already being used in lun0. Then simply add them physically into the drive enclosure, add them to lun0 by using the Array Configuration Utility (ACU) and then once the lun0 expansion has completed (usually takes about 15 minutes per GB of disk drive space on the lun) use the utility appropriate for the particular OS that is using the lun to expand the lun on the OS.

I believe the commnand would be something like:

expand unit 0 disk###-disk###
