HPMM Soft Failure Codes

ATTENTION
The HPM I/O Link Interface periodically monitors the integrity of each resident driver circuit on
the I/O Link Interface. This capability did not exist until the introduction of the HPM. There is a
possibility that upgrading to an HPM from a PM or APM, while retaining the existing IOPs, could
uncover some marginal link drivers. These marginal IOP I/O Link Interface drivers, although still
able to function, will generate I/O Link Interface driver errors and the accompanying Soft
failures.
If no I/O Link Interface driver errors are reported, then all the drivers on the I/O Link Interface are
operating properly. If I/O Link Interface driver errors exist, the offending IOP or High-Performance I/O
Link card(s) should be replaced.
Errors that are logged against the I/O Link Interface resident IOP drivers are added to that IOP's (A or B)
error count in the IOM I/O Link Information display. The mnemonic IOLDRVER is also displayed
according to the IOP's DSA under the column that is labeled LAST ERR.
