Abstract: A method of operating a storage device may include determining a fault condition of the storage device, selecting a fault resilient mode based on the fault condition of the storage device, and operating the storage device in the selected fault resilient mode. The selected fault resilient mode may include one of a power cycle mode, a reformat mode, a reduced capacity read-only mode, a reduced capacity mode, a reduced performance mode, a read-only mode, a partial read-only mode, a temporary read-only mode, a temporary partial read-only mode, or a vulnerable mode. The storage device may be configured to perform a namespace capacity management command received from the host. The namespace capacity management command may include a resize subcommand and/or a zero-size namespace subcommand. The storage device may report the selected fault resilient mode to a host.

Abstract: A method may include operating a first storage device and a second storage device as a redundant array configured to use parity information to recover information from a faulty storage device, operating the first storage device in a fault resilient mode with at least partial read capability based on a fault condition of the first storage device, and rebuilding information from the first storage device in a parity space of the second storage device. Rebuilding the information from the first storage device in the parity space of the second storage device may include copying the information from the first storage device to the parity space of the second storage device. The method may further include copying the rebuilt information from the parity space of the second storage device to a replacement storage device.

Abstract: A method may include operating a first storage device and a second storage device as a redundant array, operating the first storage device in a fault resilient mode with at least partial read capability based on a fault condition of the first storage device, and rebuilding information from the first storage device on a spare storage device based on the fault condition of the first storage device. Rebuilding information from the first storage device on the spare storage device may include copying information from the first storage device to the spare storage device. The information from the first storage device may include data and/or parity information. The method may further include reading first information for a read or write operation from the first storage device based on a rebuild point of the spare storage device.
