Displays the HDLM program information.
Use one of the sub-parameters (following -sys) to specify the program information that you want to display. If you do not specify a sub-parameter, the command displays all of the program information except the information about the audit log data collection settings, the number of times the same path can be used for load balancing, the number of times the same path can be used for extended load balancing, and the value of the display-of-the-physical-storage-system-information setting.
Table 1 shows the parameters you can specify and the displayed information.
