the location. The excprpt.txt file is overwritten every time that an exception occurs. If you want to save
the information in the excprpt.txt file, you must copy the information to a new file or a new directory.
Note: In Windows, this is specified by the registry key:
HKLM\SOFTWARE\storage\SMclient\SunJVMOption1
In a typical installation with no changes in the default installation directory, the location is:

Trace facility

The SMcli program has a trace facility. The purpose of the trace facility is to collect the SMcli information
during the command execution to assist IBM Technical Support in troubleshooting SMcli problems. The
trace facility is enabled by entering -trace on the command line followed by a list of trace options
separated by colons, and optionally a -tracefile command, followed by a filename you designate for the
trace file. To get the list of options for a release, you can use the command SMcli -trace, as noted in the
example section.
The most common options for debugging interaction with the storage subsystem are:
v 0 - JAL
v 1 - JAL Detail
v 79 - All Errors and Exceptions
Note: Any time tracing is enabled, 79 - All Errors and Exceptions is also enabled.
If the storage subsystem is being managed through the Storage Manager host agent, these options would
be helpful to use:
v 2 - RPC-UTM Agent
v 3 - RPC-UTM Agent Detail
Example
The examples listed below show the profile using SMcli with tracing enabled. The tracing information is
being written to a local file for a storage subsystem named subsystemName. The storage subsystem was
previously added to the Enterprise Management window of your Storage Manager client program.
SMcli -n subsystemName -c "show storageSubsystem profile;"
-trace 0:1:79 -tracefile trace_file.txt
SMcli -n subsystemName -c " clear storageSubsystem configuration;"
-trace 0:1:2:3:79 -tracefile trace_file.txt
Trace options available with SMcli with Storage Manager version 10.77
A list of trace options that are available with SMcli in Storage Manager version 10.77. The available trace
options can also be displayed by running the SMcli command with the -trace parameter are shown in
the following table:
C:\Program Files\IBM_DS\client>SMcli -trace is an example of a missing or an invalid trace constant.
