Severity: NOTICE
Description: This message occurs when deprioritized volume gets auto promoted.
Corrective Action: (None).

Parameters: vvol_name (STRING): Volume name.
inline_process_pct (INT): Percentage of writes happened after one window.
inline_saving_pct (INT): Percentage of inline dedupe savings in each window.

Severity: NOTICE
Description: This message occurs when automatic deduplication deprioritizes a volume due to a large number of overwrites in the block fingerprint log file.
Corrective Action: (None).
Syslog Message: Automatic deduplication on volume "%s" is deprioritized: percentage of overwrites in the fingerprint log file is %d%%.
Parameters: vvol_name (STRING): Volume name.
stale_pct (INT): Percentage of cumulative stale fingerprints after the fifth iteration of automatic deduplication runs.

Severity: NOTICE
Description: This message occurs when automatic deduplication deprioritizes a volume due to potentially low storage efficiency savings.
Corrective Action: (None).
Syslog Message: Automatic deduplication on volume "%s" is deprioritized: low background savings (%d%%), low cross volume deduplication savings (%d%%) and low inline savings (%d%%) when compared total with minimum required (%d%%) .
Parameters: vvol_name (STRING): Volume name.
bkg_savings (INT): Background deduplication savings realized after the fifth iteration of automatic deduplication runs.
cvbd_savings (INT): Cross Volume deduplication savings realized on the volume.

Severity: NOTICE
Description: This message occurs when automatic deduplication deprioritizes a volume due to a large number of stale fingerprint removal operations on the volume.
Corrective Action: (None).
Syslog Message: Automatic deduplication on volume "%s" is deprioritized: significant percentage of stale fingerprint removal operations (%d%%).
Parameters: vvol_name (STRING): Volume name.
high_verify_pct (INT): Percentage of cumulative stale fingerprint removal operations after the fifth iteration of automatic deduplication runs.
