Thank you.
I like the second link referred to in that document
If there are multiple NWSDs, you should refer to document N1011369, Cross-Referencing (Device Mapping) Disk Units on i Hosted by i LPARs:

So if I have WRKNWSD MAIL1*
MAIL10 - Tape and optical so let's forget about him.
MAIL11 - CTL06
MAIL12 - CTL07
MAIL13 - CTL12
WRKHDWRSC TYPE(*CMN)
CTL06 - U9009.42A.7805730-V3-C371
CTL07 - U9009.42A.7805730-V3-C372
CTL12 - U9009.42A.7805730-V3-C373
And we use a naming convention in which C371 ties to C371 on the guest, for example
Host:
chhwres -r virtualio -m RACK1 -o a -p RACK1HST --rsubtype scsi -a "adapter_type=server,remote_lpar_name=MAIL1,remote_slot_num=371" -s 371
Guest:
chhwres -r virtualio -m RACK1 -o a -p MAIL1 --rsubtype scsi -a "adapter_type=client,remote_lpar_name=RACK1HST,remote_slot_num=371" -s 371
I verified, via our HMC, on the client, that the adapter id 371, matches the Partner Adapter 371.
This should tie in nicely with
Guest
1. Issue the STRSST command.

4. Select Option 1. Display disk configuration status
5. Press F9 = Display disk unit details              
However, instead of seeing 371, 372, 373 I am seeing 115, 116, 117.

I could work with this.  But only because I know that 371 contains 10 storage spaces, which matches 115 0-9. 372 contains 6 storage spaces which matches 116 0-5.  373 contains 2 storage spaces which matches 117 0-1.
I'd rather see the card match the adapter id, as shown on that web site.
