Zpool device weirdness

Weird duplicate device in one of my nested raidz1s - device is shown as both online and unavailable, with a hot spare showing up as degraded as well.

Any thoughts on how I should proceed?

Code:
root@storage# zpool status tank
  pool: tank
 state: DEGRADED
status: One or more devices are unavailable in response to persistent errors.
        Sufficient replicas exist for the pool to continue functioning in a
        degraded state.
action: Determine if the device needs to be replaced, and clear the errors
        using 'zpool clear' or 'fmadm repaired', or replace the device
        with 'zpool replace'.
        Run 'zpool status -v' to see device specific details.

ddi_fm_service_impact(9F)				   Kernel Functions for Drivers 				 ddi_fm_service_impact(9F)

NAME
ddi_fm_service_impact - report the impact of an error SYNOPSIS
#include <sys/ddifm.h> void ddi_fm_service_impact(dev_info_t *dip, int *impact); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI) PARAMETERS
dip Pointer to the dev_info structure impact Impact of error DESCRIPTION
The following service impact values are accepted by ddi_fm_service_impact(): DDI_SERVICE_LOST The service provided by the device is unavailable due to an error. The operational state of the device will tran- sition to DEVI_DEVICE_DOWN. DDI_SERVICE_DEGRADED The driver is unable to provide normal service, but it can provide a partial or degraded level of service. The driver might have to make repeated attempts to perform an operation before it succeeds, or it may be running at less than its configured speed. A driver may use this value to indicate that an alternative device should be used if available, but that it can continue operation if no alternative exists. The operational state of the device will transition to DEVI_DEVICE_DEGRADED. DDI_SERVICE_RESTORED The service provided by the device has been restored. The operational state of the device will transition to its pre-error condition state and DEVI_DEVICE_DOWN or DEVI_DEVICE_DEGRADED is removed. DDI_SERVICE_UNAFFECTED The service provided by the device was unaffected by the error. CONTEXT
The ddi_fm_service_impact() function can be called from user, kernel, or high-level interrupt context. ATTRIBUTES
