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.
