Abstract
Securely removing system capabilities, being available to at least one logical partition, from that partition, the partition being hosted by a computer system running an operating system. The system capabilities are available to a boot loader of the computer system, wherein the boot loader is started in the logical partition. The logical partition remains activated while removing the system capabilities. A removal request is initiated by the boot loader; and a deconfigure command is performed by the boot loader.
Claims20
A computer-implemented method of securely removing system capabilities, being available to at least one logical partition, from a logical partition, the logical partition being hosted by a computer system, the computer-implemented method comprising:
- initiating, by a boot loader started in the logical partition of the computer system, a removal request to remove system capabilities available to the boot loader;
- and
- performing, by the boot loader, a deconfigure command to remove the system capabilities, the logical partition to remain activated while removing the system capabilities.
A computer program product for securely removing system capabilities, being available to at least one logical partition, from a logical partition, the logical partition being hosted by a computer system, the computer program product comprising:
- a computer readable storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
- initiating, by a boot loader started in the logical partition of the computer system, a removal request to remove system capabilities available to the boot loader;
- and
- performing, by the boot loader, a deconfigure command to remove the system capabilities, the logical partition to remain activated while removing the system capabilities.
A computer system for securely removing system capabilities, being available to at least one logical partition, from a logical partition, the logical partition being hosted by a computer system, the computer system comprising:
- a memory;
- and
- a processor in communication with the memory, wherein the computer system is configured to perform a method, said method comprising:
- initiating, by a boot loader started in the logical partition of the computer system, a removal request of system capabilities available to the boot loader;
- and
- performing, by the boot loader, a deconfigure command to remove the system capabilities, the logical partition to remain activated while removing the system capabilities.
