DL380 G5 P400 Raid issue / Extend Raid1

[jbi]

Hello,
we've a DL380 G5 with a P400 Raid Controller.
Konfiguration as follws:
Raid A:
2x72GB SAS (434916-001) in Raid-1
Raid B:
2x146GB SAS (418399-001) in Raid-1
Now we want to extend Raid B by adding 2-4 Disc wihout destroying the existing Raidset.
Will we be able to do this using the ACU?
Can I migrate the Raid to level 5 ?
Any suggestions are welcome ;-)

Best regards, JBI
