Managing I/O connectivity issues

A data storage system of a data storage network including a host system, a switch and the data storage system, the data storage system including executable logic that implements a method including:

• the switch identifying a connectivity issue associated with I/O communications between the data storage system and the host system;
• responsive to the switch identifying the connectivity issue, receiving at the data storage system a notification from the switch specifying the connectivity issue associated with I/O communications between the storage system and the host system;
• responsive to the data storage system receiving the notification from the switch specifying the connectivity issue, the data storage system querying the switch for additional information pertaining to the connectivity issue identified in the notification from the switch;
• responsive to the data storage system performing said querying the switch for the additional information pertaining to the connectivity issue identified in the notification from the switch, the data storage system receiving from the switch the additional information pertaining to the connectivity issue;
• compiling the additional information into issue report information;
• and
• communicating the issue report information to a user of the data storage network.

For a data storage network including a host system, a switch and a data storage system, computer-readable media having software stored thereon, the software comprising:

• executable code that controls the switch to identify a connectivity issue with I/O communications between the data storage system and the host system;
• executable code that, responsive to the switch identifying the connectivity issue, controls the data storage system to receive a notification from the switch specifying the connectivity issue associated with I/O communications between the storage system and the host system;
• executable code that, responsive to the data storage system receiving the notification from the switch specifying the connectivity issue, controls the data storage system to query the switch for additional information pertaining to the connectivity issue identified in the notification from the switch;
• executable code that, responsive to the data storage system querying the switch for the additional information pertaining to the connectivity issue identified in the notification from the switch, controls the data storage system to receive from the switch the additional information pertaining to the connectivity issue;
• executable code that compiles the additional information into issue report information;
• and
• executable code that communicates the issue report information to a user of the data storage network.
