Checking Low Latency Transport operation
Use the
lltstat
command to verify that links are active for LLT. This command
returns information about the links for LLT for the system on which it is typed.
See the
lltstat
(1M) manual page.
In the following example,
lltstat
-n
is typed on each system in the cluster.
To check LLT operation

Log into system01.
# lltstat -n

Note: Each system has two links and that each system is in the
OPEN
state. An
asterisk (*) denotes the system on which the command is typed.
With LLT configured correctly, the output of
lltstat
-n
shows all of the
systems in the cluster and two links for each system. If the output shows
otherwise, you can use the verbose option of
lltstat
. For example, type
lltstat
-nvv | more
on a system to view additional information about
LLT. In the following example,
lltstat
-nvv
|
more
is typed on a system in
a two-node cluster.
