Embodiments include methods, apparatus, and systems for managing resources in a storage system. One embodiment includes a method that discovers storage resources for arrays in a cluster storage system. A table defines how the resources are divided among the arrays and is provided to the arrays so each array can identify which resources to manage.

Managing resources in cluster storage systems

A storage device is configured with one or more processes that receive, process, and pass on jobs from a source. The number of jobs received by a process is compared with the number of jobs completed and/or passed on by the process. If the number of jobs that are received is disproportionate to the number of jobs completed and/or passed on by the process, a hang may exist and a corrective action, such as resetting, may be performed along with a request for all or some of the jobs to be resent.

Process job flow analysis

A method, system, and program product is provided for configuring a target device, the method comprising the steps of: receiving a log-in request to connect the target device to a host, wherein the log-in request includes a host designator; accessing a table of host designators and associated O/S types; determining if there is a match of the log-in request host designator to a host designator in the table; and selecting an O/S type protocol associated with the match to the host designator. In a preferred embodiment of the present invention, the host designator is a worldwide name. In a further embodiment of the present invention, the step is provided of determining if a mode parameter is set for a default O/S protocol; and selecting that default O/S protocol unless there is a match of the log-in request host designator in the table.

Method and system for implementing host-dependent SCSI behavior in a heterogeneous host environment

A data storage device may be constructed with a disk array; an array controller for controlling the array; and a queue for queuing commands from a host system to the disk array. Programming installed on the array controller adjusts a logical size of the queue to optimize performance.
