This section discusses the interaction of layered products and rolling upgrades:
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. 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. Table 4-6 Blocking Layered Products
