7.4.3 System-stopped removal


7.4.3 System-stopped removal
This section describes the workflows for system-stopped/hot and system-stopped/cold FRU removal. References to detailed descriptions are written in the workflow. See any of them as required.
Note - System-stopped/cold removal of the SPARC M10-4S when every SPARC M10-4S is in the cold state is not supported.
Initialization must be done when the SPARC M10-4S to be removed and the SPARC M10-4S where the master XSCF operates are in the hot state. Use the initbb command from the XSCF shell of the master XSCF.
A SPARC M10-4S removed without initialization will not operate normally.
System-stopped removal has the following patterns:
System-stopped/hot removal (for an internal disk or PCIe card)
System-stopped/hot removal can be performed on an internal disk and a PCIe card. Perform the following procedure to remove the unit.
