Replacing the microcode (or firmware) offline

Microcode, also known as firmware, is usually replaced online to prevent the loss of pool and pair data in shared (or control) memory.

If it is needed to be replaced offline (for example, when changing the configuration of shared memory), pool and pair information in shared memory is lost, and pools and pairs must be recreated.

 There are some terminology differences among VSP storage systems.

The terms "microcode" and "firmware" refer to the same thing. The term "microcode" is used for VSP G1000, and the term "firmware" is used for VSP G200, G400, G600, G800.

The terms "shared memory" and "control memory" refer to the same hardware. The term "shared memory" is used for VSP G1000, and the term "control memory" is used for VSP G200, G400, G600, G800. In this topic, "shared memory" is used to mean either.
