1. From the Logical Hardware Resources display, select the Display System
Information
option.
2. Record the local system type and local system serial number with the
information you recorded for the system’s HSL I/O bridge resource name, HSL
loop number, type-model, and serial number (See the procedure “Determining
if a tower is configured as switchable” on page 149).
3. Record the power controlling System type and System serial number from the
SPCN System Information field. The power controlling system’s type, model, and
five digits of the serial number are shown in the second line of the tower’s
panel.
4. Record the System type and System serial number from the Alternate System
Information field. This is the system that the ownership of resources in the
tower can be switched to for any resources in the tower that are configured as
switchable.
5. Are the Local system type and Local system serial number the same as the SPCN
system type and SPCN system serial number?
v Yes = The local system is the power controlling system for the tower. You
can perform service procedures requiring power off and power on of the
tower from the local system if the local system is also the owner of the
switchable resources in this tower. Continue with the next step of this
procedure.
v No = The local system is not the power controlling system for the tower.
Service procedures requiring power off and power on of the tower cannot be
performed from the local system. Continue with the next step of this
procedure.
6. Record which system is the current owner of switchable resources in the tower.
Note: The current owner is determined by locating the term Owner which will
be displayed with either the SPCN system information or the Alternate
system information. From the Owner system, you can use the Hardware
Service Manager (HSM) to work with switchable resources in the tower,
