US 9,286,056 B2 · Reducing storage facility code load suspend rate by redundancy check

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.

Dependent claims

A method for code load processing, comprising:

while performing code load processing of a set of modules of a same module type,
determining, with a processor of a computer, 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.

7 more elements

A computer system for code load processing, comprising:

one or more processors, one or more computer-readable memories and one or more computer-readable, tangible storage devices;

program instructions, stored on at least one of the one or more computer-readable, tangible storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, to perform:
while performing code load processing of a set of modules of a same module type,
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.

while performing code load processing of a set of modules of a same module type,
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.
