Example embodiments relate to automatic cluster-based failover handling. In example embodiments, a first node included in a high availability cluster may receive a failure signal from a second node included in the high availability cluster, where the failure signal indicates a failure in the second node. The failure signal may also indicate a second port in the second node that is or will be inactive due to the failure, the second port being associated with a second port address. The first node may activate a first port of the first node, where the first port was previously inactive before being activated. The first node may assign a first port address to the first port, wherein the first port address is the same as the second port address.

Automatic cluster-based failover handling

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.
