Record the failed resource and use Table 5-3 for future reference.

Resource hostname
It is possible to determine the resource by using the data gathered (including the
serviceable event). See to Table 5-4 to cross-reference the FRU locations.

U*-P1-R(1-8)-R(16-27) or U*-P1-R(1-8)-R(29-40) and no other
FRU
Two separate locations with the same unit location (U*) and of
the format: U*-P1-R(1-8). Indicates a failure in an interface
between two hubs
Check for any previous records that match the same failure. If previous records are found,
often the problem is recovered already and no further action is needed.
If the serviceable event indicates an LR-Link cable assembly and the only FRU information
in the FRU list is U*-P1-T9, contact IBM immediately and open a problem management
record (PMR).
Determine the location of the failure:
– Record the location code (for example, U787A.001.1234567). On the EMS, use xCAT
to cross-reference the unit location to frame and drawer.
– Use xCAT procedure to cross-reference the unit locations and determine the octant for
the QCM, as shown in Table 5-5 on page 305.
