Original Abstract Submitted
A method for facilitating storage system upgrades is disclosed. In one embodiment, such a method includes identifying host systems configured to access a storage system. The method identifies a current host code level for each host system. The method determines a latest storage code level for the storage system that is supported by each host system at its current host code level. The method reports the latest storage code level to a user to enable the user to upgrade the storage system to the latest storage code level without upgrading any of the current code levels of the host systems. In certain embodiments, reporting the latest storage code level further includes reporting an overlapping range of storage code levels that are supported by each host system at its current code level. A corresponding system and computer program product are also disclosed.
