Upgrading IBM Storage Scale

Edit online

This section lists the steps for upgrading IBM Storage® Scale.

The upgrade process is based on the CDP Private Cloud Base support matrix to ensure that the correct software stack compatibility versions are adhered to.

For example, CDP 7.1.7 supports IBM Storage Scale 5.1.1.2 and 5.1.1.3. Both these IBM Storage Scale releases contain the same IBM Storage Scale CSD and HDFS Transparency versions. If you want to upgrade from IBM Storage Scale 5.1.1.2 to 5.1.1.3 while staying at CDP 7.1.7, you only need to upgrade the IBM Storage Scale version on the CES HDFS Transparency IBM Storage Scale client nodes.

IBM Storage Scale upgrade process
You can upgrade IBM Storage Scale either manually or by using the installation toolkit.
Note:
  • Upgrading to version 3.2.2-stream is only possible from gpfs.hdfs-protocol version 3.2.2-5 or higher. Therefore, users must first upgrade to version 3.2.2-5 before proceeding to upgrade to any version from 3.2.2-6 onwards. For example: If users intend to upgrade from version 3.2.2-1 to 3.2.2-8, they must initially upgrade from 3.2.2-1 to 3.2.2-5, and subsequently proceed from 3.2.2-5 to 3.2.2-8.
  • To upgrade to version 3.1.1-stream, users must have gpfs.hdfs-protocol version 3.1.1-14 installed. Hence, it is necessary to first upgrade to version 3.1.1-14 before attempting to upgrade to any version from 3.1.1-15 onwards. For example: If users aim to upgrade from version 3.1.1-10 to 3.1.1-17, they should initially upgrade from 3.1.1-10 to 3.1.1-14, and then proceed from 3.1.1-14 to 3.1.1-17.
Upgrading IBM Storage Scale by using the Installation toolkit
For upgrading IBM Storage Scale by using the installation toolkit, see Installation toolkit upgrade process for HDFS Transparency. This will upgrade all the IBM Storage Scale nodes in the IBM Storage Scale cluster.
Note: The installation toolkit automatically updates only the HDFS package when the HDFS protocol is enabled. To check if HDFS protocol is enabled, run the ./spectrumscale node list command.
Upgrading IBM Storage Scale manually
  1. For upgrading IBM Storage Scale manually, see the following:
  2. Upgrade the HDFS Transparency package on each node by running the rpm -Uvh gpfs.hdfs-protocol-3.1.1-<version>.<os>.rpm command or by following Manual rolling upgrade for HDFS Transparency.
