RE: Can a standard i5/OS V7R1 LPAR be migrated/converted to a client NWS LPAR?

Larry,

Virtual optical sounds good.
I think I've also done the remote virtual optical, so the save will actually reside on the new host.
Problem, Pencor06, new host, currently has no virtual slots.
Will I have to IPL Pencor06 (new host) at any point for the new HMC Profile changes?
I need to review my notes and Pete Massiello PDF - Building Virtual IBM i partitions on hosted IBM i.
I also need to configure/build the Ethernet Bridge.

Paul

BRMS Sure, that will work, just follow the how to recover your system report.

You could do the save to virtual optical, then mount that virtual optical in a device on Pencore06 and IPL the new PenCore07 via the NWSD.
I effectively do this with go licpgm option 40 as the save. Virtual tape is not supported for this.

Both options require exactly the same NWSD and NWSSTG options and the NWSD's must be varied on at the point you intend to begin using the new virtual storage.

To do the save/restore option you would make all the changes to the profiles active just prior to activating Pencor07 for the restore. If you cannot restart Pencor06 to make those changes live you can do those dynamically first. Hopefully you've allowed for sufficient virtual slots on that partition!!!

Larry,

Option 1 "appears" much easier.
I may try both.

1) With each method, you must first create the NWS objects on the new host, correct?
2) At what point in option 1 are the necessary HMC profile changes for Pencor07, from physical to virtual?
3) Tape is not normally available on Pencor07, are there other options, virtual tape possibly?
4) Is it Ok to use BRMS instead, we no longer use SAVE 21/RESTORE 21?

Why would Restore 21 not work?
- Create all the NWSSTG objects.
- Create NWSD objects
- Link them all
- Make the tape drive used for the SAVE 21 available.
- Restore.
I have done MANY of these with no issue.

Now if Pencor07 and Pencor06 live on the same physical server but each have their own disks then there is a way to migrate Pencor07 as a Physical partition into a Guest partition on Pencore06 without any restore at all.

1) Add virtual SCSI server adapters to Pencor06
2) Add virtual SCSI client adapters to Pencor07
- NOTE DO NOT remove any of the hardware RAID stuff at this point.
3) Create needed NWSSTG objects on Pencor06.
4) Create needed NWSD objects on Pencor06.
5) Link the above storage to the above NWSDs.
6) If you did 1 and 2 dynamically you should now see all the new disks on PenCor07.
7) IPL Pencor07 to DST.
8) Use work with disks and copy disk unit data for the Load Source disk unit to the first virtual disk unit created in PenCor06.
9) The system will IPL Back to the new disk unit.
10) ADD all the remaining virtual disks to PenCor07. DO NOT use "And Balance" for this add.
11) Remove all the remaining physical disks from PenCor07. This will move all that data from the physical to the virtual disks.
12) Wait for 11 to complete, then use operator panel functions in DST to power down the partition.
13) Modify the partition profile to remove physical disk controllers and designate the virtual scsi adapter for IPL.

Done. Now you have a virtual Pencor07 and some extra hardware laying around.

I'm back to this old thread.
I want to take Pencor07, currently a sandbox LPAR, no important data, which currently exists with all its own hardware, convert it to a new NWS client LPAR which will be hosted by Pencor06.
I don't think Restore 21 will work.
Would it simply be easier to build the Pencor07New NWS from scratch on Pencor06.
Except for all the current Pencor7 system configuration settings, there is no data on Pencor07 of any importance.

I thought of another solution that might be easier.
Can a current NWS client be moved, renamed, and reconfigured to a new host.
Could I copy current inactive NWS client Pencor08, from one host Pencor07, to another host Pencor06.
Then I need a process to IPL/reconfigure this new client Pencor08Copy from its new host Pencor06.

This is in preparation for my 2016 P7 to P8 migration, which will be "collapsing" Pencor07 to a NWS client.

As Rob suggested you can use multiple hosts but I would only do that transitionally *OR* if I really wanted to have storage mirrored between two hosts. Uses a lot of disk but gives (in theory at least) a bit of extra redundancy.

Larry,

I currently have 3 LPARS, 05, 06, 07, all with their own hardware.

This will only work if the new client (08) will be on the same current host (05), which they are not, correct.
In my scenario, the new client (08) will be hosted from a different
LPAR (06) then the existing LPAR (05)

SAVE and REsTORE (option 21) is the documented 'it works' procedure.

BUT you can also:

Build the host partition.
Create the 'virtual' storage there to host the current 'physical'
partition. (CRTNWSSTG)
Add this 'virtual' storage to the 'physical' partition.
Use live disk migration to move all but the load source 'physical'
storage to 'virtual' storage.
IPL to DST for the load source migration (DEDICATED) Finally IPL to the new 'virtual' load source with a new partition profile.

You might have an outage as low as an hour this way. I have done several of these always successful.

You DO need twice (plus a little) the disk capacity available to pull this off BUT you likely would have that because you wouldn't virtualize unless you intended to build other partitions.
