Previously, the Dell Compellent Disks check incorrectly reported disks in a not-healthy state as UNKNOWN instead of CRIT. The SNMP health value 2 (not healthy) was not recognized by the health state mapping — it expected 0 — causing the check to fall back to the unknown state.

This has been fixed. Disks reporting SNMP health value 2 are now correctly flagged as CRIT.
