Information to Read Before Installing MPE/iX 7.5 PowerPatch 5

“ Relocation Failed” Possible during System Boot

by Jim Hawkins, MPE/iX Lab

With patch MPEMXQ3 (or superseding patches and Power Patches) a “PDC relocation failed” message may

appear on the system console soon after performing an ISL> START on A-Class and N-Class systems. After

the message appears, the system boot-up will proceed without interruption and the system will function

normally.

Example console output from A-Class:

ISL> start norecovery

If this message appears the changes made in MPEMXQ3 will not take effect on your system. This message

typically appears only after a “TC” reboot. After an “RS” reboot the PDC relocation should always be

successful. Therefore those wishing to enable MPEMXQ3 may do so by performing an RS Reboot.
