Rob,
On mail1, you should put in the exclude resources for the Optical & Tape, so that the other NWSD will provide that. This way one NWSD has the disks, and the other NWSD has the optical and tape. Then if you are going to boot from DVD, put the I_BASE_01 in the DVD, do a manual IPL of the partition. The partition should point to the SCSI which is "hosting" the optical. Also, make sure you put a 7 or 9 on CTL05 & CTL06 so you really know which ones they are.

Following section "Creating an IBM i logical partition that uses IBM i virtual I/O resources" starting at pdf page 125 (printed page 117) of "Power Systems Logical Partitioning" available at
http://pic.dhe.ibm.com/infocenter/powersys/v3r1m5/topic/iphat/iphat.pdf
On my HMC I created the new guest lpar.
Load source: Client SCSI Slot 2
Alternate restart device: Client SCSI Slot 3
The Guest lpar has the following:
adapt
Type id Server Partner Required
Client SCSI 2 gdihq(2) 5 Yes
Client SCSI 3 gdihq(2) 6 Yes
Server Serial 0 Any Partition Any Partition slot Yes
Server Serial 1 Any Partition Any Partition slot Yes
The Host lpar has (both dynamically and in profile config - verified)
adapt
Type id Server Partner Required
Ethernet 2 N/A N/A Yes
Ethernet 3 N/A N/A Yes
Server SCSI 4 Any Partition Any Partition Slot Yes (just was
there)
Server SCSI 5 MAIL1(4) 2 No
Server SCSI 6 MAIL1(5) 3 No
Server Serial 0 Any Partition Any Partition slot Yes
Server Serial 1 Any Partition Any Partition slot Yes
On gdihq I enter WRKHDWRSC *CMN and I see (subsetted)

Verified that the settings for this lpar are D mode IPL.
Tried to start it using Activate Profile and it died with B2004158.
Shut it down immediately. Varied on NWSD's MAIL1 and MAIL1TO. Tried again. Same error. Hmm, I wonder if loading a disc into the optical drive will make a difference? :-) Do I need to vary off tape/opt on GDIHQ first?

Rob,
On your NWSD to the guest LPAR do NOT restrict the tape drive (
RSTDDRVRSC Parm ) either by name, *ALLTAPE or *ALL.
Now vary OFF the tape drive on the host LPAR.
The drive should appear and be available to the GUEST lpar, simply
vary it on.
Should be as simple as that.
Twist: IBM recommend that you have your guest's disk on a separate
v-SCSI channel from Tape and Optical which means that you need TWO NWSDs
configured and to do that you need TWO vSCSI pairs between the guest and
the host. I configure the first NWSD to have the disk on it and
configure RSTDDRVRSC(*ALL) on that one. For he second NWSD I append the
letters "TO" (for Tape and Optical) to the name to keep it straight in
my head [ SO NWSD one might be GUEST1 and the other GUEST1TO ] Now
you can Vary off the ..TO NWSD should you need to make changes and you
won't upset the guest LPAR.
Also personally I do not use Power Controlling on these type of
LPARs.
Hope that helps!

I've got HOST lpar with 2844&280D fiber tape card in an 0595.
Can I share that with GUEST lpar other than dynamically moving those two
cards? That's not too hard to do, just looking at alternatives.
Can I somehow ?virtualize? this so that both can be saving at the same
time?
