Re: VIOS iSCSI vs. Fibre Channel with NPIV

I did 100% of the drive mapping on the HMC, removing the vSCSI drives from
the partition and mapping the Fibre devices to the correct ports. You are
correct it's really easy.

The command line in VIOS is an unmitigated disaster. You can't use even
the
most rudimentary actions that any Unix has, IE: arrow up to bring back the
last command, backspace over a line to correct a typing error etc. Sadly
they could put a decent shell in there but alas, I guess us non Unix types
are too stupid to understand (I actually think it's the other way around,
the Unix guys seem to think that behavior is OK)

I just completed a second partition conversion from internal DASD vSCSI to
NPIV and decided to not bring up the VIOS console and use only the HMC to
accomplish the job, and was successful, so it can be done and it was easy.

Now off to setup the split backplane on the POWER 7 box to build the dual
VIOS.....

I have to admit, VIOS is starting to win me over particularly with the
management mainly in the HMC code. The only command I had to run on
the VIOS side was CFGDEV then a command or two to verify the Fibre
logged in (it did).

Sorry that I misunderstood about where you were coming from storage-wise.

You know you can see all the mappings via the HMC and change them too for
NPIV?

While I like ... well like isn't really the appropriate term ...
using the command line because it feels faster, I'm forcing myself to
attempt to be VIOS command line free.

cfgdev normally runs without intervention due to a DLPAR operation. If
not,
there's the operations -> run vios command to take care of it.

select no LPARs (V7R7xx HMCs) and navigate Configuration -> Virtual
Resources -> Virtual storage management -> Virtual Fibre Channel tab.

The new V8R810 code does it different, but gives lots more information
about
the VFCs.

Next release of HMC code is even better.
