Sometimes, multiple FRUs or procedures are called out for replacement by
an SRC listed in the service action log (SAL). Each FRU or procedure has a
priority, and procedures are always in priority order, from highest to lowest
priority. Do the following:
Replace all high priority or mandatory FRU or procedure callouts at the
same time (as a block).
If the problem persists after replacing or performing the high priority
callouts, then replace or perform the medium priority FRU or procedure callouts
one at a time unless a medium grouping priority is associated with the callout.
A medium grouping priority, shown with an A, B, or C, means that you need to
replace all the FRUs or procedures in that group at the same time (as a block).
Finally, if the problem still persists after replacing or performing all
the medium priority callouts, then replace or perform the low priority FRU
or procedure callouts one at a time.
The priorities of the FRU and procedure callouts are shown in the following
ways, depending on how you view the SAL.SRC:
Advanced System Management Interface (ASMI): The ASMI shows a priority
with each callout in the log.
Control panel: The control panel shows one of the following priorities
with each callout:
H = High
M = Medium
MA = Medium group A
MB = Medium group B
MC = Medium group C
L = Low
Hardware Management Console (HMC): In the Service Focal Point on the HMC, the
view of the problem data for a serviceable event displays the FRU replacement
priority as High, Medium,
and so on.
Service Action Log: In the SAL, the Part Action for the FRU in the view
of the event shows the replacement priority. For more information about how
to interpret the part action code, see Using the Service
Action Log or use the help function for the SAL view.
