Implementing a Simple Spectrum Scale/GPFS Single Node Cluster

GPFS Single Node Cluster

The above is the fully qualified name of the node. If you are not using fully qualified names then you would just put gpfsnode1 or whatever your node name is.

At this point, reboot the SCALE LPAR. After the reboot, check that you see all the disks and that they have the correct PVIDs, etc.

Installing the Software

The next step is to install the SCALE software and any fixes – in my case, SCALE 4.2.3.0 and then an upgrade to 4.2.3.4. The installation files were delivered as two .tgz files that I downloaded. They were uploaded to /usr/local/soft and unzipped and untarred (you will need gzip to be able to unzip them). The files provided were:

Spectrum_Scale_Dat_Management-4.2.3.0-ppc64-AIX-install.tgz
Spectrum_Scale_Dat_Management-4.2.3.4-ppc64-AIX-update.tgz
Each was untarred into a different directory
/usr/local/soft/spectrumscale/scale4230
/usr/local/soft/spectrumscale/scale4234

The install was then very simple:

cd /usr/local/soft/spectrumscale/scale4230
smitty install and install everything
cd /usr/local/soft/spectrumscale/scale4234
smitty update_all

If you have not already installed dsh you should also install it as this will let you talk to other nodes in the system if you add them later. Go to the AIX 7.2 base and install the dsm.dsh fileset. It will also install the dsm.core and Java7_64.jre 7.0.0.370 filesets. You should then go to your update directory and update them to the same level as the operating system (TL and SP). I would also recommend using flrtvc to find the latest security ifixes and efixes along with the latest java, openssl and openssh levels and they should be downloaded and installed so the system has all known security patches installed.

You can now check your levels:

lslpp -l | grep ava
  Java7_64.jre             7.0.0.610  COMMITTED  Java SDK 64-bit Java Runtime
  Java7_64.jre             7.0.0.610  COMMITTED  Java SDK 64-bit Java Runtime

  gpfs.docs.data             4.2.3.4  COMMITTED  GPFS Server Manpages and

oslevel -s

If ‘lppchk -v’ comes back clean and ‘instfix -I | grep ML’ shows no missing filesets then I normally run bosboot, set the bootlist and reboot. After that I take a backup prior to installing the cluster.

CLUSTER INSTALLATION

Create /usr/local/etc/gpfsnodes.txt - it should contain: gpfsnode1.mydomain.com This is separate to the gpfs-nodes.txt file you already created – use whatever node name you put in that file.

Also on gpfsnode1 create /usr/local/etc/gpfsdisks.txt - it should contain the names 
of all the disks to be used by SCALE:
hdisk4
hdisk5
………
hdisk40
