lltshow - Low Latency Transport (LLT) Protocol kernel data utility
lltshow -p port
lltshow -n node
lltshow -l link
lltshow -e event
The lltshow utility displays the contents of LLTs kernel structures and trace buffers internal to the protocol. It is primarily a debugging tool.
-b Display the LLT kernel trace buffer, which shows the most recent packets transmitted and received. -p port Display the kernel structure representing the port. -l link Display the kernel structure representing the link. -n node Display the kernel structure representing the node. -e event Display the statistics for a given LLT event. You can specify the value of the event as one of the following:
1 - timer interrupt
2 - out of band heartbeat
-s Display the LLT statistics structure. The lltstat command is the recommended alternative. -t Display the last few delayed timeouts. -B Display the statistics of the LLT buffer pool. The LLT buffer pool allocates memory for the packets that are delivered to the client of LLT at the receiver node. This option is supported only on selected versions of Linux.
Linux Start Crash tool with the vmlinux (kernel image) file and vmcore (coredump) file as arguments. Execute the following commands at the crash prompt to use the LLT Crash plugin:
- mod -s llt
- extend /opt/VRTSllt/lltcrash.so
Once the plugin is loaded, the lltshow command can be used at the crash prompt, with the same options as seen above.
1 Copy kdb plugin from /opt/VRTSllt/lltdrv64.kdb to /usr/lib/ras/autoload directory.
Start kdb with the system dump and then the lltshow command can be used at the kdb prompt, with the same options as seen above.
Solaris Pass the following additional options to lltshow command:
-u unixfile: Path to kernel image file.
-c system dumpfile: Path to system dump file.
