9.2.3.2 Bringing Down a Cartridge Tape Drive Using SCF
STOP Command (Sensitive Command)
Use the SCF STOP command to terminate access to a storage device in an
orderly manner. This means that the device isn’t stopped until current
activity ends. When the STOP command finishes, configured devices are
left in a STOPPED state, substate DOWN. The devices remain in the
system configuration database.
When the last path to a device is stopped, an implicit refresh operation is
also performed. This is a general “cleanup” operation so that the device will
not have any changed buffers or file control blocks outstanding.
