Expanding Raid Array: DL360 (733732R-001) With Smart Array P420i

[TampaPaul]

Aparently I can only have 2 Logical drives on the DL360 Gen 8 (Product ID: 733732R-001) with the P420i?
Goal: Use all drives (4 X 120GB SSD, 1 X 800 SSD)

Had: 2 Raid 1+0 logical drives (with identical 120GB SSD Drives),.  I tried to add a 5th physical drive (800GB SSD Drive) with just a RAID 0 config, with the following results:
    Recognized new drive in ACU, but no option to create array (could mark as spare, flash ID LED)
    HP Smart Storage Administrator CLI recoginized drive - howver gave the error:  "Reason: Max array count reached" when executed create comand.

So:  Consolidated content onto 1st Raid drive A
Deleted Raid Drive B
Current configuration (2 unassigned drives to hopefully add to ARRAY A,  Create ARRAY B with 800GB)

assigned ARRAY A
physicaldrive 1I:1:1 (port 1I:box 1:bay 1, Solid State SATA, 120 GB, OK)
physicaldrive 1I:1:2 (port 1I:box 1:bay 2, Solid State SATA, 120 GB, OK)

unassigned
physicaldrive 1I:1:3 (port 1I:box 1:bay 3, Solid State SATA, 120 GB, OK)
physicaldrive 1I:1:4 (port 1I:box 1:bay 4, Solid State SATA, 120 GB, OK)
physicaldrive 2I:1:5 (port 2I:box 1:bay 5, Solid State SATA, 800 GB, OK)

Tried to add unassigned 120GB drives to A  
In ACU:  Would only allow me to make a signle new array using the drives.   (No option to manage / expand)

In MCU, tried comand:  ctrl slot=0 array A add drives=1I:1:3-1I:1:4.  Results:
Error: This operation is not supported with the current configuration. Use the
"show" command on devices to show additional details about the configuration.
Reason: Transformation size zero. This may indicate that there is no battery or a failed battery on the controller.

According to my research, the 420i should permit this operation?

Dont want to start from scratch and restore from backup.  As of now, that appears to be my only option.  Very dissapionted in my P420i capabilites.   Am I missing some type of feature?  All suggestios appreciated!

So aparently I need one or more of:
HPE Optional Upgrades HPE 512MB P-series Smart Array Flash Backed Write Cache 661069-B21
HPE 1GB P-series Smart Array Flash Backed Write Cache 631679-B21
HPE 2GB P-series Smart Array Flash Backed Write Cache 631681-B21
And or HPE Smart Array SR SmartCache

Any advice on which of these works on the P420i?  Anything else needed?

[Jimmy Vance]

The SKU# you've listed ships as a P420i/ZM controller. FOr advanced features such as expanding an array you need a cache module.  Any of the three FBWC modules you've listed will work with the controller.
