Prerequisites for upgrading the master console

This topic provides an overview of the prerequisites for upgrading the master console.

Before you upgrade the master console, you must meet the following prerequisites:

Ensure that your system meets the master console hardware and software requirements provided in the IBM System Storage SAN Volume Controller Model 2145-XXX Hardware Installation Guide.
You must be logged into the master console server using a user ID with administrative privileges.

If you are upgrading the master console software from version 3.2 or an earlier version, you might be required to uninstall some components that were previously included with the master console. Table 1 provides a list of master console components that are not supported beginning with version 4.2 and the prerequisite actions to take.
