The chassis VPD in the I/O subsystem drawer
identified by the location code could not be
resolved. This may be an indication that more
than one FRU in the drawer was replaced during
a service action. If this is the case, reinstall the
original FRUs in the drawer, then replace the
FRUs one at a time.
If only one FRU was replaced and this error
code occurred, call service support.
