Showing Device Information

Before you attempt to perform any DR operation, use the showdevices(1M) command to display the device information, especially when you are removing devices.

To Show Device Information
  1. Use the showdevices(1M) command to display the device information for the domain.


    % showdevices -v -d A
    

    The above command displays the device information for all of the devices in the domain. Refer to the showdevices(1M) man page to learn how to display device-specific information.

    The above command produces the following output for CPUs in domain A (the following is an example only).


    CPU
    ----
    domain   board   id   state     speed    ecache    usage                
    A        C1      40   online    400      4
