US 8,806,022 B2 · Establishing communication path group identification for multiple storage devices

Abstract

Embodiments of the disclosure relate to setting up a logical path group identification for multiple data storage devices. An aspect of the disclosure concerns a computer implemented method that comprises receiving a host command to establish a group of connection paths between the host and a plurality of storage devices, identifying the group of connection paths, adding each one of the storage devices to the group of connection paths, and reporting to the host those storage devices that could not be successfully added to the group of connection paths. The method maintains host access security to the storage devices by not grouping a device when it is a reset event state.

Dependent claims

A computer program product comprising a computer readable storage device having computer readable program code embodied therewith, the computer readable program code comprising:

program code configured to receive a command indicating an operation comprising at least one of establish, disband, and resign with respect to a connection path group of logical connection paths between a host and a plurality of storage devices, wherein the command indicates the plurality of storage devices and the connection path group to which the operation is to be applied;
program code configured to perform the operation indicated in the command with respect to the logical connection paths of the connection path group and each one of the storage devices indicated in the command;
and
program code configured to report to the host information on a success or failure of the operation performed with respect to the storage devices.
