What type are those SAN LUNs reporting in as? 6B22-050? 2145-050?
Something else? (Something-109 comes to mind...)

Hi Larry
This is the Midrange Systems Technical Discussion (MIDRANGE-L) mailing list
that's where I got to, but for some reason the SAN LUNs don't show up as
protected and then the system wants to protect them.
I am presuming there is something the V7k administrator needs to in order
for the disk to show up as protected; what configuration step could they
be
missing here - any clues ?
Any configuration on the i side we need to do in SST ?
Caveat: for reasons slightly beyond our control we are doing this without
a
HMC on a single partition system.

Evan,
When you start Mirroring you are starting it for an ASP.
Mirroring
will pair up all disks in that pool which are not already protected by
either Mirroring or RAID.
Once you start Mirroring on the ASP any disks added to it will
automatically be Mirrored UNLESS they are already protected either by
RAID
or by the storage subsystem (SAN or Host partition).
So the Secret is don't add the SAN LUNS to the system until
after
you have mirrored the SSDs. The SAN LUNS are supposed to me flagged as
already protected so you will be allowed to add them to the system
without
them being mirrored by IBM i.

Hi guys
This is the Midrange Systems Technical Discussion (MIDRANGE-L) mailing
is it possible to start mirroring on a pair of disks without starting
mirrorign on every other disk in the system ? If so, what are the steps
to
achieve this ?
I have a system which has a pair of SSDs in the base enclosure but the
rest
of the storage is intended to be provided by a SAN (V7000). The problem
is
that starting mirroring keeps wanting to protect the SAN LUNs, or adding
the LUNs to the ASP causes the system to want to configure mirroring on
the
newly added disk units.
I've looked in the info centre and found a few different PDFs on Disk
management but primarily they talk about starting mirroring on the disk
pool when I really just want to start it on a pair of disks and leave
all
the other disks without protection - at least as far as the i is
concerned.
The only thought at this point is to start RAID on the disks prior to
adding them to the ASP and then end RAID once they are added. But this
sure
seems like the long way around.
Is this possible ?
