RE: Status unmatch HMC and Power 8 server.

Larry,
I learned how to setup external storage for i using the GUI’s (Storwize, switches, HMC) but once I found out how to copy/paste the commands to the CLI I’ve never looked back. This is a major time saver during installs. I still do use the HMC for creating the new LPARs though but this may change with the advancement of the “Enhanced View” on the HMC.

For overall productivity the command line cannot be beat. This age old
argument wages on. The secret to using it successfully though for me is
a cheat sheet of commands along with an excel spreadsheet.

The cheat sheet is all the stuff I use a lot like adding an adapter or
moving something or starting or stopping a partition or installing from
network.

The spreadsheet though is the magic. Because we have MANY partitions
they are listed in a nice table with the server, partition, profile,
osver, cpu, cpu pool, memory, vlan1 vlan2 ..., VTL assignment, etc and
whatnot. I fill that in for each new partition.

In the next tab I merely enter the partition number in the upper left
and it fills in all the blanks with the exact command needed to create
that partition as well as the virtual connections to the VIO servers.
Copy Paste 5 or 6 times and done. Under 30 seconds.

Then there is a command to start it and one to stop it to generate the
virtual WWNs and one to list them. Another 30 seconds. Then add those
numbers (Just the last characters) to the table.

Next tab are the commands to feed into VIO1 and VIO2 to assign the
proper fcs ports. Takes maybe 2 minutes.

Now on the next tab are the 5 commands each to add that partition to
each of three fiber switches. (SAN 1, SAN 2, and Tape) About 3 minutes
to do all of that.

Next tab is the SAN tab, it too reaches back and pulls in the numbers so
we can create the host definition, the SAN LUNs, and link them to the
Host, all in a minute.

And we're done. Now it's a simple matter of IPLing the partition from
somewhere, be that network so it can installed or tape so it cab be
restored.

Doing all that in 5 separate GUI's would take hours.
