How can I create a Raid-1 and A Raid-5  using Adaptec AIC-7901 Ultra320 SCSI controller on my HP ML150

Posted on 2010-09-13

I need to create Hardware Raid 1 and Raid 5 in a HP ML150 G@ server. I see there are 2 SCSI cards sitting on the slots in the computer. There are 6 SWapable hard drives in the hard drive cage. A cable connects the Adaptec AIC-7901 Ultra 320 SCSI to the bottom of the cage holding the harddrives.
The 2nd SCSI card (LSI-LOGIc PCI-X Ultra 320 SCSI) is not connected to any drives and I do not see any cable from it to go to any where.
Please advise how to persue my goal.

I am sorry for the typo in server name and model. It is HP ML150 G2.

You need to press the appropriate key when the machine is posting to get into the array configuration utility in order to configure the arrays. The key combo should be CTRL+A for the Adaptec controller. You will see it prompt you to press CTRL+A to access the controller BIOS or something similar.

I would remove the un-used controller since it will also have it's own hot-key and if it is not connected, it doesn't need to be there.

After using CTRL+A I had the followings:

Configure SCSI Controller Settings
SCSI Disk Utilities
Taped Based One Button Disaster Recovery.

When I click on SCSI  Disk Utilities Iget the followings:

SCSI ID #0    Compaq BD0728856A  
SCSI ID #1    Compaq BD0728856A
SCSI ID #2    Compaq BF14689B
SCSI ID #3    Compaq BF14689B
SCSI ID #4    Compaq BF14689B
SCSI ID #5    Compaq BF14689B
If I press Enter key on the ID #0 I get information about the Hard drive: 73 GB
I checked everyoption from Config and also Untilities it does give me RAID option.
Please Advise.

Do you mean that the AIC-7901 does NOT give you the RAID option?

Yeah, it looks like that AIC-7901 does NOT do RAID.

Check the model on the LSI card and see if it supports RAID.

If not, an 8 port SATA raid card can be had on eBay for about $100.

Let me know how you plan on proceeding.

I checked the LSI20320C-HP after taking the Adaptec out, It doesn't give me any option to create RAID.
The 6 Hard hard drives are SCSI hard drives. Two of them were set as Software raid-1 and 4 others as software raid-5. The OS on the box was 2003 standard. I am going to install win 2008 on this box.
I thought I have to have a SCSI controller to do the Raids.
Do you still think I should get SATA RAID CARD?

No, sorry, I was thinking about the ML150 G3's or G4's that have SATA or SAS.

You can actually pick up an older SCSI u320 RAID card for $30 or so off of eBay. Check with Steven at Hi-Tech Assets through eBay, he usually has a box of them. And they are the actual HP ones that would come in an HP server....

Sorry about the confusion. Working too many things at once... :-)
