摘要: A method, system, and computer program product for use in upgrading disk drive firmware in a data storage environment, comprising selecting a first physical disk from a set of physical disks, the first physical disk having firmware; wherein the physical disks are mapped to a set of logical disks, wherein the mapping of the physical disks to the set of logical disks includes a RAID system, removing the first physical disk, wherein based on the RAID system, removal of the first physical disk is transparent to I/O to the set of logical disks, and upgrading the firmware of the first physical disk while allowing I/O access to the set of logical disks.

摘要: Described are techniques for managing a data storage system. First energy information for each of one or more enclosures of the data storage system is determined. Second energy information for the data storage system based on information including the first energy information for the one or more enclosures is determined. It is determined whether any of the first energy information for each of the one or more enclosures and the second energy information for the data storage system are within a predetermined amount of one or more associated thresholds. If it is determined that any of the first energy information for each of the one or more enclosures and the second energy information for the data storage system are within a predetermined amount of one or more associated thresholds, one or more actions are taken prior to reaching the one or more associated thresholds.
