Hi,

I have got a question regarding installing a Adaptec RAIDOk 7805 driver.

Ok what I wanted to find out is if I can add the RAID later.

So here are the steps I am thinking of doing.

1. Slipstream the Adaptec Raid 7805 driver into the Vmware ESXi 5.1 disk.
2. Install ESXi 5.1

-----

At a later stage after the inital ESXi install.

1. Put an Adaptec 7805 Raid controller into the sytem.
2. Vmware ESXI will detect the driver (plug and play? kind off)
3. Create the RAID datastores for ESXi to use.

So is Vmware ESXi "smart" enough to do that or do I really need to
have the RAID card in there before the install?

Thanks,

Ward.

You can add the driver to the installation media or you can add the driver later.

BUT, if the ESXi installer finds no suitable storage at installation it will abort the installation.

The creation of the RAID array on your disks, is a function of the RAID controller, and ESXi cannot do this. It expects to find a logical disk (RAID array) which it can create a datastore (VMFS partition).

I've had a very quick glance at the Hardware Compatibility Lists and cannot find the Adaptec card you mention for ESXi 5.1.

Check the VMware HCL (Hardware Compatibility Lists) here

EDIT:- Just found it:-

      aacraid version 5.2.1.29900

Looking at the driver, you will need to include it in the installation media, because it's not included. and the plain installation is likely to abort.

Hi,

Thanks for your response.

My plan was to install it with non-raid disks first - install everything first on local SATA disks.

Then put the raid card in then create the RAID disk with the Adaptec utility - reboot the machine - and add the new (raid disk) as a single datastore.

So would that work?

I assume from what you say ESxi would then detect the new drive?

Thanks,

Ward

If ESXi installer finds compatible storage e.g. SATA it will install, if it does not like your storage it will abort.

later you can drop in the Adaptec card, and add the drivers.
