Error Management
For troubleshooting purposes, HDLM collects information and stores it into log
files. The error information to be collected can be filtered out by error level,
and then stored into the log files.
The following figure shows the flow of data when error information is
collected on a host which is running HDLM.
Figure 2-14 Flow of Data When Collecting Error Information
Logs might be collected in layers below HDLM, such as for the SCSI driver.
