Abstract
A technique includes communicating with a plurality of input/output (I/O) modules to cause a firmware image to be transferred to the I/O modules. The I/O modules are each associated with the plurality of storage device enclosures, and the I/O modules are serially coupled together in a chain establishing a processing order among the I/O modules. The technique includes rebooting the I/O modules to cause the I/O modules to use the communicated firmware images, where the rebooting includes rebooting the I/O modules in a second order counter to the processing order.
