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

Monitoring CIP
Because CIP resides on both the NonStop host system and the CLIM, monitoring it requires use of
the Subsystem Control Facility (SCF) and the CLIMCMD CLI.
On the NonStop Host System
Monitoring CIP Processes
To monitor the CIP processes on the NonStop host system, you use the SCF commands:
• STATS CLIM, to display protocol statistics for individual processes on the CLIM
• STATS MON, to display statistics pertaining to the interaction of CIP processes on the NonStop
host system with applications using the socket interface
For more information about these commands, see Chapter 10 (page 216).
Monitoring the Interface to the CLIM
To monitor the interaction between CIP processes on the NonStop host system and individual CLIMs,
you use the SCF commands:
• STATUS MON, to display the status of the interaction of CIP processes on the NonStop host
system with individual CLIMs, for example, fabric status.
• STATUS CLIM, to discover whether a given CLIM is present and, if so, whether it is started or
stopped and whether it is currently being traced. The detail option also displays information
about the physical connection of the CLIM to the NonStop host system.
For more information about these commands, see Chapter 10 (page 216).
On the CLIM
SCF commands on the NonStop host system can show only a limited amount of information about
the operation of the CLIM and its TCP/IP protocol stack. More information is available using
commands that run on the CLIM itself.
Monitoring CLIM Processes
You use the CLIM psclim script to monitor CLIM-specific processes.
This script is derived from the Linux ps command and reports information such as the process ID,
memory and CPU utilization, start time, and run status of specific processes on the CLIM.
For detailed information, see “Displaying System Information” (page 93).
Monitoring CLIM Devices and Network Interfaces
You use the CLIM climstatus script to monitor CLIM-specific resources. You can invoke the script
without options to monitor a wide range of CLIM devices or specify options to find out the status
of a particular resource:
• The s option provides information about the ServerNet.
• The l option provides information about the Local Area Network (Ethernet).
• The r option provides information about the Kernel IP routing table.
• The h option provides information about Linux file-system disks and disk space.
See “Displaying CLIM Status Information With climstatus” (page 87) for the syntax of this command.
Configuring Bonded Interface Failover (IP CIP)
To set up interface-to-interface failover, use these CLIMCMD {clim-name | ip-address}
climconfig commands:
