| 发明名称 | Port throttling across an operating system restart during a hot upgrade | ||
| 摘要 | A method includes tagging, by a processor executing a first operating system kernel, a region of a volatile memory used by a first storage area network (SAN) adapter driver coupled to a SAN adapter, and decoupling the first SAN adapter driver from the SAN adapter. A boot of a second operating system kernel is then initiated while preserving in the tagged region of the volatile memory contents stored therein. After the boot, a second SAN adapter driver is then coupled to the SAN adapter. | ||

| 主权项 | 1. A method comprising: tagging, by a processor executing a first operating system kernel, a region of a volatile memory used by a first storage area network (SAN) adapter driver coupled to a SAN adapter, the first SAN adapter embedded in the first operating system kernel or in a userspace outside the first operating system kernel; decoupling the first SAN adapter driver from the SAN adapter; initiating a boot of a second operating system kernel while preserving in the tagged region of the volatile memory contents stored therein; and after the boot, coupling a second SAN adapter driver to the SAN adapter. | ||
