MAINTAINING COMPUTER SYSTEM OPERABILITY
First Claim
1. A method comprising:
- in response to a requirement for failover from a first resource to a second resource, testing, by one or more processors, an availability of the second resource, wherein the first and second resources are redundant resources of a network-connected data processing apparatus that is communicatively coupled to at least one host computer;
in response to a positive determination of the availability of the second resource, initiating, by one or more processors, the failover; and
in response to a negative determination of the availability of the second resource, providing, by one or more processors, an indication of unavailability, wherein the network-connected data processing apparatus is communicatively coupled to at least one host computer.

Abstract
Maintaining operability of a network-connected data processing apparatus is provided. In response to a requirement for failover from a first resource to a second resource, one or more processors tests an availability of the second resource, wherein the first and second resources are redundant resources of a network-connected data processing apparatus that is communicatively coupled to at least one host computer. In response to a positive determination of the availability of the second resource, one or more processors initiates the failover; and in response to a negative determination of the availability of the second resource, one or more processors provides an indication of unavailability.
