Abstract

Provided are techniques for code load processing. While performing code load processing of a set of modules of a same module type, it is determined that a first module in the set of modules is not in an operational state. It is determined that a second module is a redundant module for the first module. In response to determining that the second module is in an operational state and has already completed code update, the code load processing is continued. In response to determining that the second module is in an operational state and has not already completed code update, it is determined whether there is a third redundant module that is in an operational state. In response to determining that there is a third redundant module that is in an operational state, the code load processing is continued.

First claim

The invention claimed is:

1. A cloud system providing code load processing, comprising:
a cloud infrastructure;
at least one cloud computing node in the cloud infrastructure, wherein the cloud computing node includes one or more processors, one or more computer-readable memories and one or more computer-readable, tangible storage devices, and program instructions, stored on at least one of the one or more computer-readable, tangible storage devices of the cloud computing node for execution by at least one of the one or more processors via at least one of the one or more memories, the at least one cloud computing node comprising at least one set of modules, to perform operations for:
code load processing of a set of modules of a same module type from the at least one set of modules by,
determining that a first module in the set of modules is not in an operational state;
in response to determining that there is at least one redundant module for the first module in the set of modules,
determining that a second module is a redundant module for the first module;
in response to determining that the second module is in an operational state and has already completed code update, continuing the code load processing;
in response to determining that the second module is in the operational state and has not already completed code update, determining whether there is a third module that is another redundant module for the first module and that is in an operational state; and
in response to determining that there is the third module that is in the operational state, continuing the code load processing; and

in response to determining that there is no redundant module for the first module, suspending the code load processing.

2. The cloud system of claim 1 , wherein the operations further comprise:
in response to determining that the second module is in the operational state and has not already completed code update and that there is no third module that is another redundant module for the first module and that is in the operational state, suspending the code load processing.

3. The cloud system of claim 1 , wherein the operations further comprise:
in response to determining that the third module is in the operational state, updating firmware for the second module while continuing to use the third module.

4. The cloud system of claim 1 , wherein the set of modules form a component.
