Abstract

An approach is provided for upgrading components of a cluster. One or more components of at least one server of a cluster of servers are determined to be upgraded. Status information of the cluster, the at least one server, or a combination thereof is determined. It is determined whether to initiate another upgrade of one or more other components of the at least one server, another one of the servers, or a combination thereof based, at least in part, on the status information.

Claims

1. A method comprising facilitating a processing of and/or processing (1) data and/or (2) information and/or (3) at least one signal, the (1) data and/or (2) information and/or (3) at least one signal based, at least in part, on the following:

at least one determination to initiate an upgrade of one or more components of at least one server of a cluster of servers;

status information of the cluster, the at least one server, or a combination thereof; and

at least one determination whether to initiate another upgrade of one or more other components of the at least one server, another one of the servers, or a combination thereof based, at least in part, on the status information.

2. A method of claim 1, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

at least one determination of whether to revert the upgrade of the one or more components, one or more previously upgraded components, or a combination thereof based, at least in part, on the status information.

3. A method of claim 1, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

at least one determination of whether to perform a check point of the cluster, the at least one server, or a combination thereof based, at least in part, on the status information.

4. A method of claim 1, wherein the upgrade, the another upgrade, or a combination thereof are part of a sequential upgrade process.

5. A method of claim 4, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

at least one determination of whether to suspend the sequential upgrade process based, at least in part, on the status information.

6. A method of claim 5, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

at least one determination to disable an ability to resume the sequential upgrade process after a predetermined period of time.

7. A method of claim 4, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

at least one determination that a predetermined number of the one or more components, a predetermined number of the servers, or a combination thereof have been upgraded; and

at least one determination that the sequential upgrade process is at least substantially complete is based, at least in part, on the determination with respect to the predetermined number of the one or more components, the predetermined number of the servers, or a combination thereof.

8. A method of claim 4, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

a topology of the cluster,

wherein the sequential upgrade process is based, at least in part, on the topology.

9. A method of claim 1, wherein the status information includes at least one of a connectivity status among the cluster, the at least one server, the other one of the servers, a management server, or a combination thereof and an operational status of the one or more components, the one or more other components, or a combination thereof.

10. A method of claim 1, wherein the (1) data and/or (2) information and/or (3) at least one signal are further based, at least in part, on the following:

at least one determination that the status information indicates an issue; and

at least one determination to generate a message requesting an input for specifying whether to continue, suspend, or abort the sequential upgrade process.

11. An apparatus comprising:

at least one processor; and

at least one memory including computer program code for one or more programs,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following,

determine to initiate an upgrade of one or more components of at least one server of a cluster of servers;

determine status information of the cluster, the at least one server, or a combination thereof; and

determine whether to initiate another upgrade of one or more other components of the at least one server, another one of the servers, or a combination thereof based, at least in part, on the status information.

12. An apparatus of claim 11, wherein the apparatus is further caused to:

determine whether to revert the upgrade of the one or more components, one or more previously upgraded components, or a combination thereof based, at least in part, on the status information.

13. An apparatus of claim 11, wherein the apparatus is further caused to:

determine whether to perform a check point of the cluster, the at least one server, or a combination thereof based, at least in part, on the status information.

14. An apparatus of claim 11, wherein the upgrade, the another upgrade, or a combination thereof are part of a sequential upgrade process.

15. An apparatus of claim 14, wherein the apparatus is further caused to:

determine whether to suspend the sequential upgrade process based, at least in part, on the status information.

16. An apparatus of claim 15, wherein the apparatus is further caused to:

determine to disable an ability to resume the sequential upgrade process after a predetermined period of time.

17. An apparatus of claim 14, wherein the apparatus is further caused to:

determine that a predetermined number of the one or more components, a predetermined number of the servers, or a combination thereof have been upgraded; and

determine that the sequential upgrade process is at least substantially complete is based, at least in part, on the determination with respect to the predetermined number of the one or more components, the predetermined number of the servers, or a combination thereof.

18. An apparatus of claim 14, wherein the apparatus is further caused to:

determine a topology of the cluster,

wherein the sequential upgrade process is based, at least in part, on the topology.

19. An apparatus of claim 11, wherein the status information includes at least one of a connectivity status among the cluster, the at least one server, the other one of the servers, a management server, or a combination thereof;

and an operational status of the one or more components, the one or more other components, or a combination thereof.

20. An apparatus of claim 14, wherein the apparatus is further caused to:

determine that the status information indicates an issue; and

determine to generate a message requesting an input for specifying whether to continue, suspend, or abort the sequential upgrade process.
