To Resolve the Problems if Encountered

1. Fix an HP Integrity system with the “Bad Address (14)” read error by

following the steps in the above “To Avoid These Problems” section.

Other CD or DVD media read operations (like SD-UX) not using the

default (4K or 8K) BPS may also need to take these steps. This read-error

problem doesn’t occur on HP 9000 (PA-RISC) systems. See Change

Request (CR) QXCR1000868519 for more information.

2. For an HP Integrity system with a system hang, follow the recovery

instructions in CR QXCR1000907205. This CR also documents the

alternatives to the steps listed in the “To Avoid These Problems” section.
