scsimgr task: removing a LUN

scsimgr is the tool of choice for getting rid of storage that is in the HP-UX kernel and the underlying storage has been pulled by your storage administrator. In this case the lun has been marked as FAILED.

HP-UX 11.31, any Operating Environment, though these tasks go easier if the OE is more current.

Zero is good, non-zero probably means you are booting.
