Volume Manager Commands
vxtrace - tracing volume tasks
vxtrace - tracing volume tasks
The vxtrace command prints kernel I/O error or I/O error trace event
records on the standard output or writes them to a file in binary format.
Binary trace records written to a file can also be read back and formatted
by vxtrace.
If no operands are given, then either all error trace data or all I/O trace
data on all virtual disk devices are reported. With error trace data, you
can select all accumulated error trace data, wait for new error trace data,
or both (the default). Selection can be limited to a specific disk group, to
specific Volume Manager kernel I/O object types, or to particular named
objects or devices.
For detailed information about how to use vxtrace, refer to the
vxtrace(1M) manual page.
