DEVICE INFORMATION SHARING BETWEEN A PLURALITY OF LOGICAL PARTITIONS (LPARs)

A computer program product for device information sharing between a plurality of logical partitions (LPARs), the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions readable and/or executable by a first LPAR of a computer to cause the first LPAR to:

• obtain, by the first LPAR, information about first devices physically connected to the computer;
• send, by the first LPAR, the information about the first devices to a storage device for storage therein;
• access, by the first LPAR, information about second devices physically connected to the computer,
• wherein the information about second devices was previously stored on the storage device by a second LPAR of the computer;
• access, by the first LPAR, a first warning stored on the storage device, wherein the first warning indicates that a first of the second devices is approaching a predetermined threshold capacity;
• in response to accessing the first warning on the storage device, determine, by the first LPAR, available resources of the first LPAR for preventing the first of the second devices from exceeding the predetermined threshold capacity;
• send, by the first LPAR, information detailing the determined available resources of the first LPAR to the storage device for storage therein;
• and
• perform, by the first LPAR, a function using the information about the second devices.

A system, comprising:

• a processor;
• and
• logic integrated with the processor, executable by the processor, or integrated with and executable by the processor, the logic being configured to:
• obtain, by a first logical partition (LPAR) of a computer, information about first devices physically connected to the computer, wherein the information about the first devices includes timestamp information of the first devices;
• send, by the first LPAR, the information about the first devices to a storage device for storage therein;
• access, by the first LPAR, information about second devices physically connected to the computer, wherein the information about second devices was previously stored on the storage device by a second LPAR of the computer,
• wherein the information about the second devices includes timestamp information of the second devices;
• and
• perform, by the first LPAR, a function using the information about the second devices.
