Cluster I/O Protocols (CIP) Configuration and Management Manual (H06.16+, J06.05+)

Figure 1 OSM Service Connection displays for CIP
For more information about using the OSM Service Connection, see the OSM Service Connection
User's Guide and the NonStop Operations Guide.
The OSM Low Level Link is used to:
• Configure CLIMs, as described in the CLuster I/O Module (CLIM) Installation and Configuration
Guide.
• Upgrade CLIM software, as described in Chapter 4 (page 133).
HP NonStop I/O Essentials
NonStop I/O Essentials is a plug-in to HP Systems Insight Manager (SIM). HP SIM is an infrastructure
management tool for HP systems that runs on the system console. The NonStop I/O Essentials
plug-in provides a graphical user interface alternative to the command line interfaces of the
CLIMCMD tool and SCF.
For more information about using NonStop I/O Essentials, see the NonStop I/O Essentials
Installation and Quick Start Guide.
Persistence
Persistence in the CLIM is provided by configuration files stored on the CLIM hard drive. Changes
made by using the CLIMCMD climconfig command line interface (CLI) to the protocol attributes
are stored and are persistent. For example:
> CLIMCMD n1002532 climconfig sysctl -update net.ipv4.tcp_keepalive_intvl 25
This command sets the time interval between the retransmissions of unacknowledged keepalive
packets to 25 seconds and the change is preserved across CLIM reboots.
The persistent CLIM configuration is backed up by the CLIM backup utility and, in the event of a
CLIM failure or CLIM hard drive failure, can be restored onto the replacement CLIM by using the
CLIM restore utility. See“Managing the Configuration Preservation” (page 113) for more information
about these utilities.
The CIP Subsystem for Internet Protocols (IP CIP)
The Cluster I/O Protocols (CIP) subsystem provides an IP facility for the NonStop system that
leverages current, open-source networking features and takes advantage of the NonStop system
architecture for application scalability. The Cluster I/O Protocols (CIP) subsystem also provides
