System and method for improving cache performance

A computer program product residing on a non-transitory computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:

• determining at least one LUN that was being controlled by a host prior to a crash event concerning the host, thus define at least one target LUN;
• preparing a Mode Select command for the at least one target LUN, wherein the Mode Select command defines control information and host identifier information concerning the host;
• processing the Mode Select command to determine if the control information and host identifier information included within the Mode Select command matches control information and host identifier information included within a buffer associated with the at least one target LUN;
• and
• if the control information and host identifier information included within the Mode Select command matches the control information and host identifier information included within the buffer, granting control of the at least one target LUN to the host.

A computing system including at least one processor and at least one memory architecture coupled with the at least one processor, wherein the computing system is configured to perform operations comprising:

• determining at least one LUN that was being controlled by a host prior to a crash event concerning the host, thus define at least one target LUN;
• preparing a Mode Select command for the at least one target LUN, wherein the Mode Select command defines control information and host identifier information concerning the host;
• processing the Mode Select command to determine if the control information and host identifier information included within the Mode Select command matches control information and host identifier information included within a buffer associated with the at least one target LUN;
• and
• if the control information and host identifier information included within the Mode Select command matches the control information and host identifier information included within the buffer, granting control of the at least one target LUN to the host.
