Quiescing input/output (I/O) requests to subsets of logical addresses in a storage for a requested operation
Provided are a computer program product, system, and method for quiescing Input/Output (I/O) requests to subsets of logical addresses in a storage for a requested operation. A requested operation is received to a subset of addresses in the storage that requires that Input/Output (I/O) requests to the subset of addresses received following the requested operation be quiesced. The subset of addresses is indicated in quiesce information. I/O requests received following the receiving of the requested operation are quiesced when one address subject to the I/O request is included in the subset of addresses. If there are in-progress I/O requests pending against the subset of addresses when the requested operation was received, then the requested operation is indicated as executable. A quiesced I/O request is executed when no address subject to the quiesced I/O request is included in the subset of addresses indicated in the quiesce information.
