% Problem
100 Description: The input/output channel
controller (IOCC) detected an internal
error.
Action: Exchange the FRU for a new
FRU.
100 Description: Unable to read or write the
POS registers.
Action: Exchange the FRU for a new
FRU.
100 Description: An SSA adapter or device
drive protocol error has occurred.
Action: Go to "Software and Microcode
Errors" on page 5-2 before exchanging
the FRU.
100 Description: The SSA adapter microcode
is in a suspended state.
Action: Run diagnostics in System Verifi-
cation mode to the SSA adapter.
If the diagnostics fail, exchange the
FRU for a new FRU.
If the diagnostics do not fail, go to
"Software and Microcode Errors" on
page 5-2 before exchanging the
FRU.
– Description: An attempt was made to log
an error against a pdisk that is not avail-
able to the using system.
Action: This problem has occurred for
one of the following reasons:
A user has deleted a pdisk from the
system configuration. In such an
instance, the hdisk that is related to
the pdisk continues to operate
normally. If the disk drive module
tries to log an error, however, this
SRN (50100) is produced. Enter the
cfgmgr command to return the pdisk
to the system configuration.
A disk drive module has tried to log an
error during system configuration. To
find the failing disk drive module, run
diagnostics to the disk drive modules
that are connected to this SSA
adapter.
