Hello Experts.
I have a need to performe cloning of sunfire v490 machine to the same machine (differs only memory).
I found here one thread for V210 ,but my situation is a little different:
So this config i have:

HDD1 146G c1t0d0
HDD2 146G c1t1d1
soft RAID-1 mirror:
 
 metastat -p
d0 -m d10 d20 1
d10 1 1 c1t0d0s0
d20 1 1 c1t1d0s0
d1 -m d11 d21 1
d11 1 1 c1t0d0s1
d21 1 1 c1t1d0s1

 metadb
        flags           first blk       block count
     a m  p  luo        16              1034            /dev/dsk/c1t0d0s7
     a    p  luo        1050            1034            /dev/dsk/c1t0d0s7
     a    p  luo        16              1034            /dev/dsk/c1t1d0s7
     a    p  luo        1050            1034            /dev/dsk/c1t1d0s7
Also in my situation i have oracle installed on it and oracle folder is mounted thru NFS where share is located on the other FreeBSD box thru FreeNAS.

My question is what do I need to do id I have a spare HDD3
which is blank. I thought of getting the HDD2 out and try to boot from it on a new box.
But I bump in those questions where on my production box the total memory is 16GB, whether on the new box it is 32GB.
So does it mean i will need the swap file to be larger than on the production box? And if I do how I can safely increase the swap partition?
Also how will be HDD3 resyncronized?
Do I have to modify any settings in raid-1 config?
What if the system will assign a new label to HDD3?
What do i need to do on the new box in order for it to boot up from HDD2?
Never had any experience with that and ask you guys if anyone can help. The farther i went was "flarcreate".
And what else i need to pay attention to as well as be aware of for not screwing up the production box.
Thank you everyone in advance.
