Disk Expansion using 5300 Smart Array

Hi all,

Have ML530 G1, running Windows 2000 SP4, using Installed Agents for Windows 2000/Server 2003 7.10.0.0
Array Configuration Utility 2.90.65.0
HP Array Configuration Utility 7.15.19.0

Have expanded the array, so have 135Gb of unallocated free space. Can I expand the 1st logical disk drive to give it all the free space.
Logical drive 1 configured as 36Mb Utilities, 10Gb C & 135Gb on Drive E. We want to expand drive E so we don't have to rebuild our Doc Stores.

When using the ACU it gives a warning to say you can't or shouldn't if using windows 2000, When using the web based ACU 7.15 it gives no warning.. Its important I get this right or my projects are going down the pan !!!!!!.

Regards to all
