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:
