IBM SY44-5902-05 Server User Manual


 
v 7 = 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.
v 8 = 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.
v 9 = 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.
v 10 = 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.
v 11 = 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.
v 12 = 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.
v 13 = 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.
v 14 = 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.
v 20 = Display system type/model
Use this option to display the system type, model, and feature code.
v 21 = 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.
v 22 = Force main storage dump
Use this option to force a main storage dump (MSD) for a partition.
