Hi UNIX admin,
I would check fmdump -eV output to see if this error is isolated or
persistent.
If fmdump says this error is isolated, then you might just monitor the
status. For example, if fmdump says that these errors occurred on 6/15
and you moved this system on that date or you know that someone
shouted at c1t11d0 on that date, then those events might explain this
issue and you can use zpool clear to clear the error state.
If fmdump says the c1t11d0 error persists over a period of time, then I
could consider replacing this device.
You can review more diagnostic tips here:

The last drive shows two checksum errors, but iostat(1M) shows no hardware
errors on that disk:
iostat -Ene | grep Hard | grep c1t11d0
c1t11d0 Soft Errors: 178 Hard Errors: 0 Transport Errors: 0
I'm not sure what I need to do, respectively how else I can determine if "the device
needs replaced".
Do I perform zpool clear, or do I need to replace c1t11d0, or do I rerun scrub?
