Abstract
An information handling system may include a host system processor and a storage resource communicatively coupled to the host system processor. The storage resource may be configured to, responsive to receiving a command from the host system processor relating an address range of the storage resource, create an entry in a drive status table stored in a persistent storage area of the storage resource, the entry setting forth information indicative of the address and a completion status of the command and update a status of the address range in the drive status table as steps of the command are completed by the storage resource, such that, if a drive event occurs preventing full completion of the command, the host system processor may access the drive status table to determine a status of the command, and take a remedial action based on the status of the command.
