While starting LLT the following error is seen in certain situations.


# lltconfig -c
LLT lltconfig ERRORV-14-2-15241 LLT not configured, use -o to override this warning

The following needs to be checked

1.Any syntax or typo errors in /etc/llttab file
2.Network interfaces defined in the /etc/llttab file i.eif bge2 is defined as, network interface in llttab for heartbeat then the same NIC card should be visible from the OS. For instance, in Solaris 10 use the following command to check the interface(s):
------------
dladm show-dev
ce0             link: unknown  speed: 1000  Mbps       duplex:full
ce1             link: unknown  speed: 100   Mbps       duplex:full
bge2            link:up        speed: 1000  Mbps      duplex: full
----------
3.Sometimes if there is any hardware or driver issue with the NIC card,  we face issues in LLT startup. Use dlpiping to check the interface or plumb an IP address and test connectivity using ping.



Example of an issue seen inllttab


#lltconfig
LLT is notrunning.

# lltconfig-c
LLT lltconfig ERROR V-14-2-15241LLT not configured, use -o to override this warning

# lltconfig -o -c

This command gave an error suggesting syntax issues in llttab file.

# cat/etc/llttab
set-nodex4200-e
set-cluster13
Link bge2 /dev/bge:2 - ether --
link bge3 /dev/bge:3 - ether --
link-lowpri bge0 /dev/bge:0 - ether- -


# vi/etc/llttab            (  corrected Link to link )
set-nodex4200-e
set-cluster13
link bge2 /dev/bge:2 - ether --
link bge3 /dev/bge:3 - ether --
link-lowpri bge0 /dev/bge:0 - ether- -



Similarly, in another instance, an extra blank line at the end of llttab file caused this issue.

a20-c4n:# cat/etc/llttab
set-nodea20-c4n
set-cluster8587
link bge2 /dev/bge:2 - ether --
link-lowpri bge0 /dev/bge:0 - ether--

a20-c4n:#


Deleted the extra line at the end of llttab file and then started  LLTagain.
# lltconfig -c

If required, you can perform load/unload of LLT modules at this point.
For example, Solaris 10
# lltconfig-U
# modinfo | grepllt
# modunload -i224
# lltconfig-c
#lltconfig
LLT is running
