How do I set up a raid 5 configuration correctly using HP smartstart 7.7 CD?

At my workplace an order for a HP Prolient DL360 G5 has arrived. I have put 6 hds in the server and wish to configure them into all into a Raid 5 configuration so that if a HD fails it can be hot swapped with another empty hd and the information rebuilt.

I have booted into smartstart 7.7 and selected the option to "deploy server"
I have next launched the ACU which shows:
Smart Array P400i in Embedded slot
SAS Array A
Logical drive 1 (209924 mb, raid 5)

Does this mean that the disk is already set for hot swapping in a raid 5 config?

It's either already setup, or merely showing you the 'suggested' configuration.
DOes the 360 have the option to hit F8 on bootup to configure the array?
If so, enter that section and verify that the array is configured there as well.

What size are your drives?

Did you create the array using the ACU? Sounds like this might be a deafult logical drive created by the distributor. I would delete the logical drive from the ACu and start again selecting all the disks and adding them to the new volume and then selecting the RAID 5 option in the ACU

Correction to above: This server has 4 x 73.g gb hds in it.

I have gone the the F8 array config utility and it states:
Logical drive # 1, RAID 5, 205.0 GB, OK

I think it is fine but can you confirm this. It seems that the disk form a Raid 5 config by default.

No, the ACU will determine that if you have more than 3 drives, you probably want a RAID 5, so that's the default that's selected, you still have to go through and confirm it.  However, if it's already showing the logical drive created, then it must have been done at some point.  If you're still concerned, I'd agree to wipe it out and start over - otherwise, simply load up the OS onto it...you'll know shortly if the logical drive isn't there... :)

You said you had 6 drives?  You now mean just 4 - so you're using 1 for overhead for parity, which should give you 'about' 216 (they should actually be 72 GB drives)

I had written my last comment before I refreshed the page but I think the default raid 5 used all avaliable 4 disks so there is no need to recreate the array. Please correct me if I am wrong.

You are right the disks are 72gb but in the F8 array utility it stated 73.X gb. Thanks for the help guys.
