You can determine whether an expansion unit is configured
as a switchable expansion unit under OptiConnect by performing the following
procedure.
Note: To perform this procedure, you must have the resource
name of the high speed link (HSL) I/O bridge resource.
- Move to the console of the system where you know the name
of the HSL I/O bridge resource in the expansion unit.
- Sign on to the System Service Tool (SST) or Dedicated Service
Tool (DST).
- From the SST or DST, select Start a service
tool, then Hardware Service Manager.
- From the Hardware Service Manager display, select Logical
Hardware Resources.
- From the Logical Hardware Resources display, select High
Speed Link Resources.
- From the High Speed Link Resources display, select the
function Include non-reporting resources.
- Move the cursor to the HSL I/O bridge resource of the expansion
unit and select the Display detail option. The Display HSL Information display appears.
- At the Display HSL Information display, locate the Mode information
of the resource.
Note: If you cannot locate the Mode information,
then this HSL resource is not part of a Cluster Resource Group (CRG)
and the expansion unit where this HSL I/O bridge resource is located
cannot be configured as switchable under OptiConnect.
- Is the mode listed as Private or is the mode not
displayed for this resource?
- Yes = the expansion unit where this HSL
I/O bridge resource is located cannot be configured as switchable
under OptiConnect. This
ends the procedure.
- No = the HSL I/O bridge resource has a
mode of switchable. The expansion unit is configured as a switchable
expansion unit under OptiConnect.
Continue with the next step of this procedure.
- Record the HSL loop number, the type-model, and the serial
number of the HSL I/O bridge resource.
Note: You will need
the type-model and serial number to identify the HSL I/O bridge on
the other system that can own this resource.
