A method and apparatus for implementing power up detection in a power down cycle to dynamically determine whether a failed component in a system prevents another Initial Program Load (IPL) or re-IPL, or result in a loss of resources. Predefined mandatory functions are called to collect power down/up data that prevents re-IPL, or results in the reduction of resources. A user is notified, allowing the customer to continually utilize the system, while ordering hardware to be replaced.

A memory system and method for storing data in one or more storage chips is disclosed. The memory system includes one or more storage dies included in each storage chip and a controller. Each of the plurality of storage dies further comprises one or more media replacement unit (MRU) groups. The controller includes a translation module, the translation module further comprising: a chip select table (CST) configured to identify one or more valid storage chips during translation for performing a read/write operation, and a media repair table (MRT) corresponding to each of storage chips, each MRT configured to identify one or more storage dies during translation for performing a read/write operation.

Examples of techniques for a thread checkpoint table for a computer processor are described herein. An aspect includes, based on detecting an early power-off warning (EPOW) signal, determine, based on a thread checkpoint table, whether a status of a thread of a processor indicates that the thread has begun a unit of atomic work. Another aspect includes, based on determining that the status of the thread of the processor indicates that the thread has begun the unit of atomic work, allowing the thread to continue execution of the unit of atomic work. Another aspect includes determining, based the status of the thread in the thread checkpoint table, that the thread has completed the unit of atomic work. Another aspect includes, based on determining that the thread has completed the unit of atomic work, suspending the thread.
