Consult the following table to determine which method to use to install an SRU or update individual packages in an Oracle Solaris Cluster configuration. Consider the extent of changes the update would make:
Use the scinstall update method to apply an SRU with significant functionality changes, The scinstall method performs additional cluster checks, to ensure that the cluster meets certain support requirements of the new software version. The scinstall method.always requires a cluster reboot.
Use the pkg update method to update individual packages and to apply an SRU with minor functional changes. A cluster reboot or node reboot is necessary only if a particular package requires it.
