Writing New Device-Clean Scripts

If you add more allocatable devices to the system, you might need to create your own device-clean scripts. The deallocate command passes a parameter to the device-clean scripts. The parameter, shown here, is a string that contains the device name (see the device_allocate(4) man page):

st_clean -[I|F|S] device-name

Device-clean scripts must return 0 for success and greater than 0 for failure. The options -I, -F, and -S help the script determine its running mode.

-I is needed during system boot only. All output must go to the system console. Failure or inability to forcibly eject the media must put the device in the allocate error state.

-F is for forced cleanup. This option is interactive and assumes that the user is available to respond to prompts. A script with this option must attempt to complete the cleanup if one part of the cleanup fails.

-S is for standard cleanup. This option is interactive and assumes that the user is available to respond to prompts.
