To unconfigure and subsequently disconnect a CPU board with memory or a memory-only board, it is necessary to first unconfigure the memory. However, some memory is not currently relocatable. This memory is considered permanent.
Permanent memory on a board is marked "permanent" in the cfgadm status display:
# cfgadm -s cols=ap_id:type:info Ap_Id Type Information ac0:bank0 memory slot3 64Mb base 0x0 permanent ac0:bank1 memory slot3 empty ac1:bank0 memory slot5 empty ac1:bank1 memory slot5 64Mb base 0x40000000
In this example, the board in slot3 has permanent memory and so cannot be removed.
Workaround: Shut down the system before servicing the board, then reboot afterward.
