I see that the zpool is on the third partition on the disk
ata-WDC_WD2000F9YZ-09N20L1_WD-WMC5C0D7E3DU-part3.
If you created the raid 10 from the installer, please follow the steps in the
admin guide [0] in the section "Changing a failed bootable device".
But instead of "zpool replace" you should run
zpool attach rpool ata-WDC_WD2000F9YZ-09N20L1_WD-WMC5C0D7E3DU-part3
/dev/disk/by-id/{new disk}-part3
The man page for the 'zpool attach' command can be viewed with 'man zpool-attach'
