For this upgrade path, use the following platform-specific commands instead of those listed in Step 4: For each node in the cluster, do the following steps. Perform any necessary operating system upgrades.
Upgrading from GPFS 3.5
Extract the IBM Spectrum Scale installation image so that all installation files rpm, deb, bff, msi, and so on are available. After all the nodes in the cluster are upgraded to 4.
At this point all code is at the upgraded level, but the cluster is not upgraded and new functions cannot be configured until the upgrade is completed.
This file system is used for CES protocol state data and it must remain mounted and up on all protocol nodes for the protocols to function.
Offline upgrade, complete cluster shutdown This scenario is applicable if you can shut down the entire cluster and perform the upgrade. Re-enable the GPFS autoload setting by issuing the following command. Regardless of which method you are using, if you want to install and configure CES protocols after upgrading to the latest level, you must create a CES shared root file system of size 4 GB or greater.
Alternatively, you can perform function additions and upgrades manually. At this point, the code is at the upgraded level, but the cluster is not upgraded 33.5 new functions cannot be configured until the upgrade is completed. You can also create this file system from multiple NSDs, each of which are replicated gprs help with redundancy. Run the necessary platform-specific commands to upgrade GPFS. At this point, you can use the installation toolkit for installation or deployment of new functions and for future upgrades.

Upgrading from GPFS 3. Confirm that the upgraded operating system level is one that is supported by the version of IBM Spectrum Scale to which the system is being upgraded. For GPFS-only configurations, the gpds is now complete. Repeat the preceding steps on each node in the cluster one by one after restarting GPFS.
