What can be changed dynamically !
I/O Slots
Only “desired” slots can be moved !
Remember i5/OS still needs IOPs
An IOP without IOA is functional but not very useful
An IOA without IOP is nothing
BUS/IOP/IOA requirements must be kept !
Remember “IOP-less” IOAs
Ethernet adapters
Cryptographic processors
... more in the future : the direction is to get away from the IOP !

iSeries. mySeries.
Dynamic LPAR
What can be changed dynamically !
An I/O slot move implies :
Deactivation of the dependent device
VARY OFF !
Deallocation of the slot
IOP/IOA gets first the “inoperative”, then “not detected” status
Reset of the IOP/IOA cache, memory, registers
Allocation of the slot to the destination partition
IOP IPL : download of its microcode, activation of the IOP
IOA initialization : download of its microcode, activation of the IOA
IOP/IOA gets the “operational” status ... some “failed” status may temporarily appears !
Activation of the dependent devices
VARY ON !
Time required !
Up to 10 minutes !
