SCF Reference Manual for the Storage Subsystem (G06.28+, H06.05+, J06.03+)

object is restarted and persist through processor and system loads (unless you load the system with
a new configuration file).
The storage subsystem includes features to manage both SCSI and Fibre Channel devices. The
Fibre Channel features are collectively called the FCS Manager. FCS Manager assigns Fibre
Channel loops for Fibre Channel disk modules (FCDMs) to the FCS monitors. FCS Manager also
passes OSM requests to the FCS Monitors.
The FCS Monitor Process
The FCS monitor process (FCSMON) is a persistent process that runs in every processor. FCSMON:
• Monitors the Fibre Channel loops that connect to the Fibre Channel disk modules (FCDMs).
• Accepts requests from FCS Manager and notifies FCS Manager about FCDM configuration
information
• Sends hardware change events and environmental status change events to $ZLOG
• Polls FCDMs for drive insertions and removals
• Polls the Environmental Management Units (EMUs) in the FCDMs
• Issues commands to the EMUs
Storage Management Foundation (SMF)
The Storage Management Foundation (SMF) uses SCF to help you manage data storage on multiple
disks. Refer to the Storage Management Foundation User’s Guide for information about:
• SMF configuration, management, and troubleshooting
• File relocation
• File protection and recovery
• Other SMF utilities
SMF uses these object types in the storage subsystem:
