AIX, stand alone LPAR

If you have sufficient free adapters (slots) in your machine:

- using IVM create a new LPAR with the desired characteristics and
- assign the required adapter slots to it
- cable the adapters for SAN and Ethernet access
- customize your SAN zoning so that the new LPAR can see a sufficient number of disks to accomodate the OS.
- using your installation DVDs install all "devices.*" filesets into the old LPAR
- pull an mksysb of the old LPAR to DVD, tape or NIM
- shut down the old LPAR
- boot the new LPAR from the mksysb medium and restore the old image
- done

You could also make the disks of the old LPAR available to the new one, shut down the old LPAR and boot the new one.
Using new disks has the advantage that nothing of the old environment can be destroyed by accident, because this environment remains untouched.

If you don't have the required adapters you must create a full system LPAR, which would involve deleting the old LPAR (install all devices.* stuff and pull an mksysb first!) and the IVM, then boot the managed system itself from the mksysb media to build the full system LPAR from it.

Out of curiosity, why cant I do th efollowing

1> Disable the SEA Virtual adapter named "Ethernet"

2> Go to the IO tab of the managed profile and create or enable one of the ethernet adapters there to be directly wired to my LPAR ?

Thanks

I thought you wanted an LPAR with directly attached network and disks!

If it's just for the network, OK, that's easier.

You can't (or at least shouldn't) "disable the SEA".

The SEA is a bridge between the real adapter(s) of the VIOS and the internal network to which the LPARs are connected, an entity persistent to the VIOS and not to a single client LPAR.

What you can do is remove the virtual Ethernet client adapter from the LPAR configuration and attach a real adapter slot, if there is one left.

Please be aware the the LPAR's network remains configured over the (now obsolete) virtual adapter, so you won't be able to access the LPAR via network after rebooting it.

You must open a virtual terminal and reconfigure the network over the new, real adapter which will show up as ent1/en1. The virtual ent0/en0  will still appear with "lsdev", but now as "Defined" instead of "Available".

Sorry I did not describe my requirements properly.  

I am going to attempt the following:

1> Remove the virtual ethenet client adapter

2> Attach a real adapter slot

In the VIrtual Adapters tab, I have the following

Ethernet        2   N/A             N/A                  Yes
Client SCSI     3   VIOS1(201)	    3                    Yes
Server Serial   0   Any Partition   Any Partition Slot   Yes
Server Serial   1   Any Partition   Any Partition Slot   Yes 

Select allOpen in new window

In the IO tab, I have the following

U78AF.001.WZS00UC-P1-T1       PCI-to-PCI bridge          Required   512
U78AF.001.WZS00UC-P1-C34-L1   Ethernet controller                   513
U78AF.001.WZS00UC-P1-C35-L1   Fibre Channel Serial Bus              515
U78AF.001.WZS00UC-P1-C34-L2   Ethernet controller                   528
U78AF.001.WZS00UC-P1-T2       PCI-E SAS Controller                  544
U78AF.001.WZS00UC-P1-C36-L1   Ethernet controller                   545
U78AF.001.WZS00UC-P1-C37-L1   Fibre Channel Serial Bus              547
U78AF.001.WZS00UC-P1-C36-L2   Ethernet controller                   560

I assume I should perform the following:

1> In the Virtual Adapters tab, delete the "Ethernet" row

2> Go to the IO tab, and mark the fourth entry as "Required"

3> While keeping the VIOS shutdown, start the LPAR independently of the VIOS

Is this correct ?

Thanks

1) ok
2) ok

3) if you bring down the VIOS, where should the LPAR get its disk from?

You still have vscsi to be served, or didn't I understand your setup?

Actually, you did understand my set up

I did not take the disk into consideration until right after I sent the note

Anything else I need to complete this task other than bring up both the VIOS and LPAR ??

Thanks

... and reconfigure the network over the new entx device, using a virtual terminal, because network access will not be possible.

I mkarked the fourth entry in the IO tab as required,

U78AF.001.WZS00UC-P1-C34-L2   Ethernet controller                   528

Select allOpen in new window

and deleted the "Ethernet" entry in the
VIrtual Adapters tab

I started the VIOS and the LPAR

Which one of these should I configure?  It does not look like en1 is available
