Non-disruptive drive firmware upgrades

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.

1. A method for use in upgrading disk drive firmware in a data storage environment, the method comprising:
selecting a first physical disk from a set of physical disks, the first physical disk having firmware; wherein the set of physical disks are mapped to a set of logical disks; wherein the mapping of the set of physical disks to the set of logical disks includes a redundant array of inexpensive disks (RAID) system; removing the first physical disk; wherein based on the RAID system, removal of the first physical disk is transparent to input/output (I/O) on the set of logical disks; upgrading the firmware of the first physical disk while allowing I/O access to the set of logical disks; wherein the allowed I/O access occurs on the set of logical disks while the first physical disk is removed, wherein the allowed I/O includes reads and writes on the set of logical disks; wherein the data storage environment is enabled to determine if the upgrading of the firmware of the first physical disk was successful; and based a negative determination, marking the firmware upgrade of the first physical disk as bad to inhibit an upgrade of firmware of other drives.
