Abstract:
1. A data storage library system in communication with a host system to receive Input/Output requests from the host system directed to data storage media in data storage cartridges maintained in the library, comprising a drive controller including a drive processor and a drive memory storing drive instructions executed by the drive processor, wherein the drive instructions are executed to confirm a receipt of a host command to the host system on behalf of a library in response to a drive receiving the host command from the host system directed to one of the data storage cartridges, wherein during a reset of the library the drive instructions are executed by the drive controller to queue host commands received from the host system and confirm receipt of the queued host commands to the host system during the reset of the library; and a library controller coupled to the drive controller, the library controller including a library processor and a library memory storing library instructions executed by the library processor, wherein in response to the reset, the library controller executes initialization instructions to initialize the library, wherein the library instructions are executed to command the drive controller to transmit the host commands, queued during the reset of the library, to the library in response to a complete of the reset of the library and the execution of the initialization instructions.
