Hi Carsten, Did anything about this configuration change before the checksum errors occurred? The errors on c1t6d0 are severe enough that your spare kicked in. You can use the fmdump -eV command to review the disk errors that FMA has detected. This command can generate a lot of output but you can see if the checksum errors on the disks are transient or if they occur repeatedly. At the very least, I would consider physically replacing c1t6d0.
