Abstract
A method, computer system, and a computer program product for soft fencing is provided. The present invention may include identifying a logical device swap occurred. The present invention may also include, in response to a logical device swap, creating a soft fence command. The present invention may then include issuing the created soft fence command.
Claims20
A method for soft fencing, the method comprising:
- processing an input-output services (IOS) record in a storage system control data set (CDS);
- creating a list of path group identifiers (PGIDs);
- identifying the created list of PGIDs associated with a production sysplex;
- associating the identified list of PGIDs with the production sysplex;
- identifying a plurality of sysplex names not associated with the production sysplex;
- identifying a logical device swap occurred;
- and
- in response to the logical device swap, creating a soft fence command.
5 more elements
A computer system for soft fencing, comprising:
- one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage media, and program instructions stored on at least one of the one or more computer-readable tangible storage media for execution by at least one of the one or more processors via at least one of the one or more computer-readable memories, wherein the computer system is capable of performing a method comprising:
- processing an input-output services (IOS) record in a storage system control data set (CDS);
- creating a list of path group identifiers (PGIDs);
- identifying the created list of PGIDs associated with a production sysplex;
- associating the identified list of PGIDs with the production sysplex;
- identifying a plurality of sysplex names not associated with the production sysplex;
- identifying a logical device swap occurred;
- and
- in response to the logical device swap, creating a soft fence command.
6 more elements
A computer program product for soft fencing, comprising:
- one or more computer-readable tangible storage media and program instructions stored on at least one of the one or more computer-readable tangible storage media, the program instructions executable by a processor to cause the processor to perform a method comprising:
- processing an input-output services (IOS) record in a storage system control data set (CDS);
- creating a list of path group identifiers (PGIDs);
- identifying the created list of PGIDs associated with a production sysplex;
- associating the identified list of PGIDs with the production sysplex;
- identifying a plurality of sysplex names not associated with the production sysplex;
- identifying a logical device swap occurred;
- and
- in response to the logical device swap, creating a soft fence command.
