This tells me everything to replace a disk.
1. sdparm -C stop /dev/sdb
2. Removing Z1F0KR3H from the chassis.

Yep, the serial number is the best suggestion so far.

Are we sure this serial number is always programmed in by the hdd
vendors so that sdparm can read it out?

With three known exceptions
- fake ones generated by some IT821X adapters in RAID mode
- certain old Maxtor PATA drives had a peculiar firmware failure where
  they changed to some kind of default serial number. Very unusual. Was
  never really fully explained and seems to have been very rare.
- drives so ancient they don't support IDENTIFY, and we don't support
  them in libata anyway !
