The fjsnap command is a tool which gathers system information necessary for analyzing the trouble at a time. When the trouble occurs by the PRIMECLUSTER system, the cause can be pursued by collecting necessary error information by the fjsnap command.
You can execute this command as follows:
Log in with system administrator authority.
Execute the "fjsnap" command.
/usr/sbin/fjsnap -a output
The file name which becomes an output destination of system information collected by using the fjsnap command for output is specified.

For details on the "fjsnap" command, see the "README" file included in the "FJSVsnap" package.
Information
Execution timings for the fjsnap command
For problems that occur during operation, for example, if an error message is output, execute the "fjsnap" command immediately after the problem occurs.
If the "fjsnap" command cannot be executed because the system hangs, collect a crash dump. Then start the system in single user mode, and execute the "fjsnap" command.
For information on how to collect a crash dump, see "C.1.2 Crash Dump."
After an error occurs, if a node restarts automatically (the node could not be started in single-user mode) or if the node is mistakenly started in multi-user mode, execute the "fjsnap" command.
If investigation information cannot be collected because the "fjsnap" command results in an error or the "fjsnap" command does not return, then collect a crash dump.
