Re: VIOS iSCSI vs. Fibre Channel with NPIV

I do know that but that does not really offer the kind of redundancy we
suggest to our customers.

This box is a "do unto yourself before doing unto customer" box. I need to
get the configuration done properly so the other engineers at Agile can
practice doing all the normal maintenance and management needed in that
environment.

Remember that if the POWER 7 box doesnt have the split backplane or you
don't have the extra SAS controller you can always boot from a lun on the
storage.

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.
