Abstract
Embodiments are directed to a method of online storage device firmware upgrades by suspending input/output (I/O) operations to the storage device upon notification of a firmware upgrade to the storage device, maintaining a stripe log that contains data stripes updated by I/O operations issued to the storage device during suspension of the storage device, triggering the firmware upgrade to the storage device while the storage device is in suspension, reactivating the disk and new firmware upon completion of the firmware upgrade, and reconstructing the updated data stripes from the stripe log on the storage device after the reactivating step.
