This section discusses the interaction of layered products and rolling upgrades:

General Guidelines

The clu_upgrade setup command prepares a cluster for a rolling upgrade of the operating system. Do not use the setld command to load software onto the cluster between performing the clu_upgrade setup command and rolling the first cluster member to the new version. If you install software between performing the clu_upgrade setup command and rolling a cluster member to the new version, the new files will not have been processed by clu_upgrade setup. As a result, when you roll the first cluster member, these new files will be overwritten.

If you must load software:

  • Wait until at least one member has rolled.

  • Install the software on a member that has rolled.

Blocking Layered Products

A blocking layered product is a product that prevents the installupdate command from completing. Blocking layered products must be removed from the cluster before starting a rolling upgrade that will include running the installupdate command. You do not have to remove blocking layered products when performing a rolling upgrade solely to patch the cluster or install an NHD kit.

Table 4-6 “Blocking Layered Products” lists blocking layered products for this release.

Notes:

The three-letter product codes are the first three letters of subset names. For example, a subset named ATMBASExxx is part of the ATM product (Atom Advanced Developers Kit), which is a blocking layered product. However, a subset named OSFATMBINxxx contains the letters ATM, but the subset is not part of a blocking layered product; it is a subset in the OSF product (the base operating system).

When a blocking layered product is removed as part of the rolling upgrade, it is removed for all members. Any services that rely on the blocking product will not be available until the roll completes and the blocking layered product is reinstalled.
