Welcome to this video demo where we show
you the procedure to install the Red Hat Enterprise Linux operating system on
an IBM power systems environment.
To get started, let's go into the hardware management console.
This HMC or hardware management console can manage multiple power systems servers,
so here we have four of them.
This is 851 through 854.
Let's pick one of these servers and
install Linux as a virtual machine on one of these servers.
So let's go into 6852.
Play video starting at ::39 and follow transcript0:39
And it looks like I have three not activated partitions.
Before installing Linux, let's view a few partition related information and
also some HMC related information.
We could do that on the graphical user interface, but
I'd like to show you some commands on the HMC command line interface as well.
So let's log into the HMC CLI.
Play video starting at :1:8 and follow transcript1:08
Okay, the first command is lshmc.
Just list some configuration relating to the HMC itself, so I'll do an attribute
of -V that will list the version of the HMC that's currently running.
So we're running version 9 released one service pack 940.
There are other attributes as well, for example,
-b will show you the BIOS level of the HMC that's currently running.
Okay, so now let's attempt to query the HMC so that it can list all the managed
systems available, the same thing that we saw on the graphical user interface.
So to get that, we'll use the lssyscfg command.
Play video starting at :1:52 and follow transcript1:52
And we need to say it -r.
What resource type are you looking for?
I'm looking for my manage systems, and we'll say -F and
then specify name:serial_num:state.
I'll explain it just now.
So -F takes in an attribute list, so I basically want the output,
but I only want the name of the managed system.
I only want the serial number of the manage system, I only want the state
of the manage system, so I've just delimited the output with a colon.
-F parameter let's you filter the output based on what you need.
So here's the output of that command.
So here we have sys851, two 854.
And sys852 is here, and it's in an operating state.
Now, what if I wanted to see all the partitions
that are available on one server?
So to do that, let's do the lssyscfg command again, but
this time we'll do the manage system -m sys852 is the name of the server.
And inside that, I want to query all the partition resources, -r lpar.
And again, we can filter the output and say name and state.
Play video starting at :3:11 and follow transcript3:11
And here you can see the available partitions in this
particular manage system.
And let's try to install Linux on this one, sys852 s1 lpar2.
That one is not activated, and it looks like we can run Linux on it.
Other things that you would like to do from your HMC,
for example, would be to see if I have enough memory available.
So let's do that using the lshw rest command, hardware resources, -r.
So in this case I'm looking for the memory resource and on which system,
on this particular system, and I want system level information.
There are many other levels of information that you can query, so
you can refer to the Knowledge Center for that.
So in this case,
we see that total available memory on the system is about 65.5 gigabytes.
And it shows me what's available and so on in this particular output.
Play video starting at :4:11 and follow transcript4:11
Okay, we can do the same thing but for
processors to see how many cores are available.
So this is a POWER8 server, it should be about 20 cores available.
20 CPU cores available on one machine, so that's really good,
and it looks like 18 of it is available for me to use.
Play video starting at :4:33 and follow transcript4:33
Now similarly, we could do lshwres, and
I could do -r io to see I/O related information, and
we could use the --rsubtype to filter the information even more.
For example, I want to see only the available I/O slots, so
I could do subtypes slot and on this 852 system.
Play video starting at :4:54 and follow transcript4:54
And here we see the available I/O slots.
So for example, this slot has got a dual port fiber channel adapter and
so on and so forth.
Now that we've seen a few commands on the HMC, let's go into our VIO server.
