disk problems with Dell PowerEdge r210 / SEAGATE ST3300656SS HS09

Hello,
Since 2017 I own the above server which my company wanted to
decomissioned. I use it since then as my bakery for FreeBSD CURRENT and
ports.

The server has two SCSI harddrives, da0 is UFS for /root, /usr etc. and
da1 is ZFS used for poudriere:

Oct 27 04:55:34 jet kernel: da1: <SEAGATE ST3300656SS HS09> Fixed Direct Access SPC-3 SCSI device
Oct 27 04:55:34 jet kernel: da1: Serial Number 3QP1NF96
Oct 27 04:55:34 jet kernel: da1: 300.000MB/s transfers
Oct 27 04:55:34 jet kernel: da1: Command Queueing enabled
Oct 27 04:55:34 jet kernel: da1: 286102MB (585937500 512 byte sectors)

Since some time this disk gives fault like the messages below and only a
power-off reset help. Here are the last two faults on October 25 and 27.

What could I do as tests or map away disk blocks so they will not be
touch again?

Thanks
