Method, system, and program for improved device blocking and suspension

A method for determining device suspension and device blocking, comprising:

• comparing local session cache usage and residual counts against limit values associated with that session, wherein the limit values comprise a device blocking count, a device blocking percent, a suspend count, and a suspend percent for the local session;
• and
• if a cache in trouble condition is detected based on the comparison, processing the cache in trouble condition to determine whether one or more volumes are to be blocked or suspended.

An article of manufacture including program logic for determining device suspension and device blocking, wherein the program logic causes operations to be performed, the operations comprising:

• comparing at least one of local session cache usage and residual counts against limit values associated with that session, wherein the limit values comprise at least two of a device blocking count, a device blocking percent, a suspend count, and a suspend percent for the local session;
• and
• if a cache in trouble condition is detected based on the comparison, processing the cache in trouble condition to determine whether one or more volumes are to be blocked or suspended.
