Expand volume

[MAK]

Forgive me guys for asking silly question. I am a novice 3par user

I have a 3par virtual volume 100GB thin provisioned, zero detect and exported to windows 2003 machine and its being used. It is part of cluster resource.

volume almost ran out, so i expanded the volume on the 3par to 200GB. But the windows is not seeing the expansion.

Should I re-export again to take effect? If I do, will I lose my drive letter assignment ?

My simple question is what should I do to take the change effect so that windows system can see the new available space.

Have you expanded the volume in the disk manager on the host ?

I know my question will be silly.

I see the new space on the disk management. I will expand it.

Thanks

Just FYI.

For windows 2003:
diskpart
list volume
Select volume 4
extend
exit
