Abstract

The invention provides a storage system software online upgrade method comprising the steps of starting a first virtual container in a storage controller, operating storage system software in the first virtual container, and processing reading-writing requests of a host via the storage system software in the first virtual container; for the upgrade of the storage system software, starting a second virtual container in the storage controller, and operating new-version storage system software in the second virtual container; forwarding new reading-writing requests of the host to the new-version storage system software in the second virtual container, and allowing the new-version storage system software to take over host businesses; destroying the first virtual container and the storage system software in the first virtual container. The method shortens the upgrade time of storage system software.

Description

technical field [0001] The invention relates to the field of storage technology, in particular to an online upgrade method for storage system software. Background technique [0002] At present, when the storage system software in the existing storage server needs to be upgraded, in order to ensure that the host business is not interrupted, the notification will switch the business among multiple controllers, upgrade the controllers one by one, and finally complete the upgrade of the entire storage server.
