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

CONSIDERATIONS
• If the param-value has multiple entries, you must specify the entries as space separated values
within single quotes.
• Changes to these sysctl parameters must be done for every CLIM in a Provider:
net.core.rmem_default◦
◦ net.core.rmem_max
◦ net.core.wmem_default
◦ net.core.wmem_max
◦ net.ipv4.ip_local_port_range
◦ net.ipv4.tcp_rmem
◦ net.ipv4.tcp_wmem
• If a sysctl is deleted, the change will come into effect only after a CLIM reboot.
• On a CLIM with MULTIPROV set to ON, the sysctl settings apply to all providers associated
with that CLIM.
• Changes to sysctl parameters should not be made when the CLIM is in STARTED state. To
change the sysctl parameters on the CLIM:
1. Stop the CLIMs and the Provider(s).
2. Alter the sysctl parameters.
3. Start the CLIMs and the Provider(s).
If the CLIM is an Open type, you must reboot it.
EXAMPLES
> CLIMCMD n100253 climconfig sysctl -update net.ipv4.conf.all.forwarding 1
> CLIMCMD n100253 climconfig sysctl -update net.ipv4.tcp_rmem '4096 87380 1048576'
> CLIMCMD n100253 climconfig sysctl -info net.ipv4.tcp_rmem
net.ipv4.tcp_rmem = 4096 87380 1048576
> CLIMCMD n100253 climconfig sysctl -info all
net.ipv4.tcp_rmem = 4096 87380 1048576
net.ipv4.conf.all.forwarding = 1
> CLIMCMD n100253 climconfig sysctl -info all -obeyform
climconfig sysctl -update net.ipv4.tcp_fin_timeout 60
#CLIMCMD expects 'exit' to be the last command.
#This is required to terminate CLIMCMD session.
