Troubleshooting HyperFabric

Running Diagnostics

-rspecifies that you want to probe a specific remote node identified by

remote_node_name. The probe is done on all operational routes to the remote node.

-Tspecifies that you want to set the tracing level for the HyperFabric software and the firmware to trace_level, which can be one or more of the following (you can specify either the keyword or the hexadecimal value):

reset or 0x0

Reset tracing to the default level for all

 

components (that is, turn off all tracing).

send_path or 0x0002 packet_data or 0x0004 packet_hdr or 0x0008 data_struct or 0x0010

Trace the HyperFabric software send path.

Trace the packet data.

Trace the protocol headers (TCP/UDP/IP).

Trace the HyperFabric software CLIC-specific data structures and events.

rcv_path or 0x0020

Trace the HyperFabric software receive path.

control or 0x0040

Trace the HyperFabric software control

 

messages.

all or 0xffff

Turn on all possible trace levels. Note that this

 

will have a severe impact on performance.

To find out what the current tracing level is, run this parameter (-T) without any keyword or hexadecimal value specified.

-Dspecifies that you want to dump the trace buffers from the kernel to a user-space file and format the data using the formatter TCP_IP. The HyperFabric software trace data is dumped into the file /var/adm/clic_ip_drv.trc and formatted.

-C TCP_IP operates in a way similar to -D TCP_IP, except that the trace data in the kernel is dumped at regular intervals to the trace file /var/adm/clic_ip_drv.trc0, and if that file gets full, to /var/adm/clic_ip_drv.trc1. So, new trace events are appended to the trace output file. This stops when tracing is turned off.

-Bspecifies that you want the size (in bytes) of the trace buffer to be

trace_buffer_size. The buffer is dynamically allocated when tracing is enabled. Also, the buffer is circular, which means that when the end of the buffer is reached, the data wraps around to the beginning of the buffer (and overwrites any previous data). If you do not specify this parameter, a default buffer is created with a size of 64k bytes.

-Fspecifies trace_file_size as the maximum size of the trace output file. For the

-D TCP_IP parameter, the file is /var/adm/clic_ip_drv.trc. For the -C TCP_IP parameter, the files are /var/adm/clic_ip_drv.trc0 (and if needed,

/var/adm/clic_ip_drv.trc1).

-ddumps the memory of the adapter identified by adapter_ID to the dump file filename. If you do not specify filename, the default file is /var/adm/clic_fw.dumpx, where x is the adapter instance number.
