Can anyone help me with the following questions?

1. Can hosts be online and doing IO to the AMS2000 when the microcode is being upgraded

2. How is the disk drive code loaded? Is it separate code or is it all bundled with the main microcode package?

3. If hosts can be doing IO, how is the code loaded on the disk drives? Is the IO somehow quiesced within the storage array bus such that this can occur? I can't see how the drive code can be loaded if t is servicing IO simultaneously.

I have been looking around for the maintenance manual but it's been hard to find on their website.

Thanks for any feedback.
