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 method for code load processing in a cloud infrastructure comprising at least one cloud computing node, wherein the cloud computing node includes one or more processors and at least one set of modules, comprising:
performing with the one or more processors of the at least one cloud computing node, code load processing of a set of modules of a same module type from the at least one set of modules by,
determining with the one or more processors of the at least one cloud computing node, 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 with the one or more processors of the at least one cloud computing node, 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 with the one or more processors of the at least one cloud computing node, 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 with the one or more processors of the at least one cloud computing node, 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 with the one or more processors of the at least one cloud computing node, the code load processing; and

in response to determining that there is no redundant module for the first module, suspending with the one or more processors of the at least one cloud computing node, the code load processing.

2. The method of claim 1 , further comprising:
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, with the one or more processors of the at least one cloud computing node, the code load processing.

3. The method of claim 1 , further comprising:
in response to determining that the third module is in the operational state, updating, with the one or more processors of the at least one cloud computing node, firmware for the second module while continuing to use the third module.

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

5. A computer program product for code load processing in a cloud infrastructure comprising at least one cloud computing node, wherein the cloud computing node comprises one or more processors, one or more computer-readable, tangible storage devices, at least one set of modules, and program instructions stored on at least one of the one or more computer-readable, tangible storage devices, and wherein the program instructions are executable by at least one of the one or more processors to perform:
code load processing of a set of modules of a same module type from the at least one set of modules by,
determining, by the one or more processors of the at least one cloud computing node, 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, by the one or more processors of the at least one cloud computing node, 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, by the one or more processors of the at least one cloud computing node, 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, by the one or more processors of the at least one cloud computing node, 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, by the one or more processors of the at least one cloud computing node, the code load processing; and

in response to determining that there is no redundant module for the first module, suspending, by the one or more processors of the at least one cloud computing node, the code load processing.

6. The computer program product of claim 5 , wherein the program code is executable by the at least one processor to perform:
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.

7. The computer program product of claim 5 , wherein the program code is executable by the at least one processor to perform:
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.

8. The computer program product of claim 5 , wherein the set of modules form a component.
