RE: Removing drives from a guested lpar.

That’s odd. Mine match but are small numbers. I wonder if it rolls over after 256? 371 - 256 is 115.

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:
http://www.ibm.com/support/docview.wss?uid=nas8N1011369

Host
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.
2. Select Option 3. Work with disk units
3. Select Option 1. Display disk configuration
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.

Subject: Removing drives from a guested lpar.

IBM i hosting disk for IBM i.

I have a guest lpar in which the business has changed and it needs far less disk.

The hosting lpar has four NWSD's allocated for this guest. The first is for tape and optical. The other three are for disk.
I want to ensure that when I remove disks from the guest using STRASPBAL and/or STRSST on the guest that I can tie that back to WRKNWSSTG on the host. This is so that I can free up space on the host for use for other tasks.
I also want to ensure that the storage links are balanced across the NWSD's. Basically keeping the 'arms' balanced across those NWSD's.

So, how do I tie the items which appear on the host when I run WRKNWSSTG NWSSTG(MAIL1*) with the items which appear on the guest when I run SST and get information like:
Type. . . . . . . . . . . . : 6B22
Model . . . . . . . . . . . : 050
Level . . . . . . . . . . . : 0
Serial Number . . . . . . . : YVJAX4S34Q42 Resource Name . . . . . . . : DD001
