I have a difficult problem to solve that has already dragged on for 
months, it all started when I was trying to replace a HD in "mirror-1", 
there were several problems with the HDD swapped, creating multiple 
records in ZFS POOL:

2172725334577304178 UNAVAIL      0     0     0  was /dev/dsk/c17t22d1s0
844126543414690630    UNAVAIL      0     0     0  was /dev/dsk/c17t12d1s0
13311585097705723147  UNAVAIL      0     0     0  was /dev/dsk/c17t21d1s0
14208018708240497353    UNAVAIL      0     0     0  was /dev/dsk/c17t13d1s0

By the current state of POOL, everything is ok, I have two hard drives 
inside the MIRROR-1 synchronized, but the records of HDs are UNAVAIL and 
the health of my pool is only DEGRADED.
I've tried to import/export POOL, zpool clear and nothing.

Can anyone help me?

zpool status:

pool: STORAGE01
  state: DEGRADED
status: One or more devices has experienced an error resulting in data
         corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
         entire pool from backup.
