snowflake-01: The other sysdisk SATADOM is failing

Two weeks ago one of the two SATADOM's used as system disk, including booting from, was diagnosed with errors bad enough to require replacement, cf. #40495 (closed).

Yesterday the other SATADOM started behaving the same way.

We should take it out of the mirror now and replace it soon.
