IBM SY44-5902-05 = Delayed power off, = Mode normal, 10 = Mode manual, 11 = Mode auto

v7 = Delayed power off

Use this option to power off a partition that has finished an IPL and is up and running. This option is similar to a white button power off from the panel. The system will attempt to write changed data to disk units, but the operating system may not reach a normal job termination. This may cause an abnormal IPL on the next restart.

v8 = Immediate power off

CAUTION:

Using this option may cause damage to system and user data.

Use this option to immediately power off a partition. This is similar to a panel function 8, so a normal shutdown is not performed for the partition.

v9 = Mode normal

Use this option to change the partition mode to normal. When in normal mode most of the panel functions will not be allowed for that partition.

v10 = Mode manual

Use this option to change the partition mode to manual. When in manual mode all panel options will be allowed for that partition.

v11 = Mode auto

Use this option to change the partition mode to auto. When in auto mode most of the panel functions will not be allowed for that partition.

v12 = Mode secure

Use this option to change the partition mode to secure. When in secure mode most of the panel functions will not be allowed for that partition. If the primary partition is in the secure mode you must then use the DST or the control panel to change modes. Panel functions will not be allowed for ANY partition if using this service function in SST on the primary partition. If a secondary partition is in secure mode, it can only be changed from the primary partition.

v13 = IPL partition on system IPL

Use this option to mark a secondary partition to automatically IPL on the next primary partition IPL. This option can only be changed from the primary partition.

v14 = Hold partition on system IPL

Use this option to mark a secondary partition to NOT automatically IPL on the next primary partition IPL. The partition will have to be started using option = 1, power on partition. This option can only be changed from the primary partition.

v20 = Display system type/model

Use this option to display the system type, model, and feature code.

v21 = Force Dedicated Service Tools

If enabled, use this option to force DST for a partition.

Attention: Place DST in debug mode or an abnormal termination of interactive jobs may occur.

If possible, end any active service functions that may be running under SST in the partition before entering option 21. Some service functions, including this one, only support one session per partition. If the interactive job terminates abnormally, the sessions will remain active for as long as system values QDEVRCVACN and QDSCJOBITV dictate. This prevents DST access to these service functions after option 21 is entered.

v22 = Force main storage dump

Use this option to force a main storage dump (MSD) for a partition.
