The meaning of this log info value is "Virtual IO has failed and has to be retried". Firmware will provide this log info value with IOC Status "SCSI_IOC_TERMINATED", whenever a drive (with is a part of a volume) is pulled and pushed back with some minimal delay. With this log info value, firmware informs the driver to retry the failed IO command infinite times, so to provide some time for the firmware to discover the reinserted drive successfully instated of just retrying failed command for five times( doesn't giving enough time for firmware to complete the drive discovery) and failing the IO permanently even though drive came back successfully.
