Hi, Anguis:

What IBM calls "parity" is in fact RAID ... (IBM basically invented RAID on the System/38 with CPF ... way back when.)

Mirroring requires pairs of disk drives -- each drive has a "mirror" so if one drive fails, the whole system can still run. You can do mirroring even on a machine that does not hava a RAID-capable disk controller (IOP).

ASPs and Independent ASPs (aka. DASD pools) are separate concepts from whether or not you choose to implement parity or mirroring.

HTH,

Can anyone point me in the right direction for the following.

I have a 9406-170 with Eight (8.5GB) HD's.
The controller card is a 75G3439 PCI Controller Card AS/400e 9406-170
w/21H5072 Card.

So can I Mirror, RAID-5, Parity Protect ?

I cannot find any documentation on what exactly Parity Protection is -
is it Mirroring or RAID ?

If I can Mirror this system - I'd like to put:
2 HD's in the System ASP
2 HD's in a User ASP
and then Mirror them all.

So would I need to:
set up two more 2 HD ASP's
a single 4 HD ASP

Then how would I go about enabling the Mirroring ?

Note: I have no PC Operations Navigator - just a dumb terminal.

Best,
Anguis
