Hi flexi,
Firstly , we must know the your hardware system ?
Maybe we can determine best choice for your needs to that.

if your system x86 arch maybe you can try "LSI or other Logic Configuration Utility Console " which appears in the boot stages..

You assume 8 disks , but has your system contains these from local or san ?
if your all disks has local ( SAS / Sata .. ) , then what is the your critical data ? ( database )
all disks are at the same or size ?

Yes , Raid5 can be good choice or maybe not for avaliable disk space or security requirements.
That can change to your needs.
For exa : you want to create hard raid 5 vol with 6 disks at size 300 GB. ( security : with "1 disk" failure )
then your avaliable space ( n x size -1 x size ) = 6 x 300 - 1 x 300 ( for total parity size ) = 1500 GB

So at the reality , what is your systems for solaris ( oracle sparc / x86 / non-oracle x86 .. )
in Sparc systems LSI raid controllers does not support for raid 5
if you will be use zfs , then you can use software raid with zfs ( zpool )


For exa :
Now i can say what i do with 6 disk in my sparc hardware.

( note : Raid Controller Support = ( 0, 1, 1e, 10 ) )


* We have 6 disks on the two raid controller..


* 4 disk for RAID 1E ( security two disk in teory but may be "one disk" to controller !! )
-----------------------------------------------------------------------------------------
( * You can create similiar this volume with your 6 disks )

* create 4 disk with RAID 1E volume ( vol1 ) --> For your database pool

Code:
{0} ok 9 b c d create-raid1e-volume              --> Create RAID 1E ( Mirroring Extending ( + Stripped ) = Striped and Mirrored disk array )

Target 9 size is 583983104 Blocks, 298 GB

Target c size is 583983104 Blocks, 298 GB
Target d size is 583983104 Blocks, 298 GB
The volume can be any size from 1 MB to 570296 MB			

What size do you want?  [570296] 
Volume size will be 1167966208 Blocks, 597 GB			--> 4 X 300 /2 = 600 GB disk space
Enter a volume name:  [0 to 15 characters] vol1
Volume has been created

Code:
{0} ok unselect-dev



* After apply this , check volume :
---------------------------------------

Code:

Code:

* If raid volume is "inactive" state then starts
Code:
{0} ok 0 activate-volume
Volume 0 is now activated

Code:
{0} ok unselect-dev

-> Now first Raid volume ( vol1 ) is Ready..




2-) The other 2 disk with RAID1 ( via the other Raid Controller port )

* Select the disk and create hard raid.

....
....

Code:
{0} ok 9 a create-raid1-volume			--> RAID 1 Mirror for Operating System ( security one disk )
....
.... same operations..


-> Now first Raid volume ( vol2 ) is Ready..


* Raid operations completed..



* I installed the Solaris OS on the this volume ( vol2 ) at the Disk Select Menu..

* when system is on :


vol2 ( in 2 disk with size 559 with RAID 1 ) ---> 2 X 559 /2 = 556 GB in OS
