2.3.4.30 PMDF Channel Queue Directories' Locations (logicaldisk, nologicaldisk)

Note

The logicaldisk keyword is only supported on OpenVMS. However, symbolic links can be used on UNIX to provide similar functionality.

The logicaldisk channel keyword is used to spread PMDF channel queues across multiple disks. Specifically, when logicaldisk is specified on a channel, the name of the corresponding channel queue changes from PMDF_QUEUE:[channel-name...] to PMDF_QUEUE_channel-name:[*...]. nologicaldisk is the default.

Use of logicaldisk therefore requires that a corresponding PMDF_QUEUE_channel-name logical be defined. Note that the logical name must be defined before pmdf cnbuild is run, because pmdf cnbuild checks for both the logicaldisk channel keyword and the existence of the logical name before it will enable this functionality.
