Virtual Disk Process Catalogs
Virtual Disk Process Catalogs
Catalogs for each virtual disk process contain:

Logical to physical file name-mapping. The Audited Name Table (ANT) file contains
name-mapping information associating each logical file name with a physical file
name.

Information about pending operations (see Pending Operations Catalogs )

Catalog version information

Information about co-located objects
Pending Operations Catalogs
All three types of SMF processes maintain a Pending Operations Table (PENDOPS).
The PENDOPS file maintains consistency by cataloging operations as they are
happening. In the event of process or system failures, the information in this table is
used to recover or abort operations that were in progress at the time of the failure.
Configuration Interfaces for SMF
SMF processes are configured and controlled by using either the Dynamic System
Configuration (DSC) facility through the COUP user interface and the Peripheral Utility
Program (PUP), or by using the Subsystem Control Facility (SCF).
DSC/COUP
For users who plan to install and run a D-series product version of SMF, DSC provides
the COUP interactive command interface for configuring the attributes of the SMF
processes themselves, such as the process run-time priority and the assignment of
primary and backup processors for the processes.
An overview on configuring and managing SMF with COUP is presented in Section 3,
Configuring and Managing SMF Processes . COUP commands that support SMF are
described in Appendix B, COUP and PUP Interfaces . The COUP interactive command
interface is described in the Dynamic System Configuration (DSC) Manual.
PUP
For users who plan to install and run a D-series version of SMF, PUP provides the
interface for establishing relationships among SMF processes, such as configuring
attributes specific to SMF, and obtaining information about the SMF processes
configured on a system. PUP commands allow you to define storage pools and
associate physical volumes and virtual disks with them. PUP also lets you control SMF
processes and retrieve information about them.
An overview on configuring and managing SMF with PUP is presented in Section 3,
