Chapter 5. Diagnosing Errors

Comparing setsp -a with System Events

SVA Path necessarily interfaces with system components at the

I/O path level, which does not support sophisticated device error

reporting. The application reports failed I/O to

/var/adm/syslog/syslog.log as well as when:

• a data path is found to have stopped functioning

• I/O is redirected to an alternate path

• the failed path resumes functioning.

Whether a path failure is intermittent or is caused by a hardware

failure can usually be deduced from the events listed in

/var/adm/syslog/syslog.log, and a faulty device can be

located physically by cross referencing the output of setsp -a.

Figure 5-1, “Example setsp -a Output for a Fully Functioning

System” shows the example configuration used in this section.
