Abstract:

Provided are a computer program product, system, and method for a computer program product, system, and method for determining an availability score based on available resources of different resource types in a distributed computing environment of storage servers to determine whether to perform a failure operation for one of the storage servers. A health status monitor program deployed in the storage servers performs: maintaining information indicating availability of a plurality of storage server resources for a plurality of resource types; calculating an availability score as a function of a number of available resources of the resource types; and transmitting information on the availability score to a management program. The management program uses the transmitted information to determine whether to migrate services from the storage server from which the availability score is received to at least one of the other storage servers in the distributed computing environment.

International Classification:

G06F 11/07

Abstract:

In one aspect, multiple data path error collection is provided in a storage management system. In one embodiment, an error condition in a main data path between the storage controller and at least one of a host and a storage unit is detected, and in response, a sequence of error data collection operations to collect error data through a main path is initiated. In response to a failure to collect error data at a level of the sequential error data collection operations, error data is collected through an alternate data path as a function of the error data collection level at which the failure occurred. Other aspects are described.
