This option allows Tivoli Storage Manager to use the Direct I/O capabilities provided on AIX. Direct I/O enhances system performance by allowing write activities to skip caching and go directly to disk. We recommend that you refer to the AIX documentation for details about Direct I/O before using this option. This option applies to eligible disk storage pool volumes, database volumes, and log volumes. If this option is disabled by specifying NO, then no Direct I/O will be performed. The default is for AIXDIRECTIO to be enabled.
