But we're keeping the same config - and the 530.
I now see the load source units are under a 9162 controller.
Do I have to mirror these? Or do they now support RAID 5? I don't believe
they did back when the system was originally put together. But was that
hardware or software that kept it from supporting RAID?
If I must mirror, how do I do this? Start RAID on the 65x2 controlled
disks, then add all disk units to the proper ASP, then come back and start
mirroring on the 9162 disks- which are in ASP 1? (The manual is unclear on
this).

From the 6xx/170 and up, the base DASD CTLR can be spec'd to support
RAID5. I don't remember off hand if it's default or extra $$

Subject: Is mirroring of 660x's load source units still
needed?
Since the days when our machine was a 9406-320, the load source unit has
been mirrored, and the rest of the disk units are all RAID-5. (We have
6606, 6607, and 6603 disk units). We are now up to a 9406-530 running
V4R4.
We are switching to an equivalent box. Is mirroring still required on the
load source unit? Or can RAID5 be used instead?
If we still mirror, do I start RAID on rest of the disk units first, then
come back and mirror the load source units?
We have 6502/6512 disk controllers.
