Expanding LUNs with Navisphere

I need to expand a couple of LUNs and am seeking advice regarding how
to proceed.

We are using a Dell/EMC Clarion 300. We have two RAID groups (1 and 2)
that had multiple LUNs on each RAID group with the LUNs assigned to
different servers (I know, bad idea). Only one server uses the two RAID
groups now and I'd like to allocate all space in each RAID group a
single LUN in each RAID group (i.e., Expand LUN 12 to use all disk
space in RAID Group 1 and expand LUN 21 to use all disk space in RAID
Group 2).

RAID Group 1:
Server F is using 60 GB (LUN 12) on RAID Group 1 (configured as RAID
1).
73 GB on RAID Group 1 is free and unallocated (no LUN created).
I want to allocate this unused 73 GB on RAID Group 1 to Server F (i.e.,
expand LUN 12 to use the additional 73 GB).

RAID Group 2:
Server F is using 250 GB (LUN 21) on RAID Group 2 (configured as RAID
5).
Server B was using 250 GB (LUN 22) on RAID Group 2.
300 GB on RAID Group 2 is free and unallocated.

I want to allocate the 250 GB (LUN 22 assigned to Server B) to Server F
and allocate the 300 GB unallocated space to Server F (i.e., expand LUN
21 to use all the space on RAID Group 2).

None of the LUNs are part of a snapshot, clone, mirror or SAN Copy
session.

Regarding RAID Group 1:
Do I need to create a LUN from the unallocated 73 GB on RAID Group 1,
then expand LUN 12 using the Expand Storage Wizard?
If so, when I expand the LUN do you recommend I choose Stripe or
Concatenate Expansion?

Regarding RAID Group 2:
Do I need to destroy LUN 22, then create a LUN using the unallocated
space, then expand LUN 21 using the Expand Storage Wizard?
If so, when I expand the LUN do you recommend I choose Stripe or
Concatenate Expansion?

Many thanks in advance to the group for any guidance.

Jeff
