What is the meaning or function of newly added options on ONTAP 9.12?
Applies to
ONTAP 9.12
Answer
raid.h.mute.timeout
Mute the periodic shutdown(halt) but retain the warning message.
NOTE:
- With the ONTAP 9.12.1 code change via Bug ID 944990 - System no longer halts if a RAID aggregate remains degraded for 24 hours, the default system behavior is changed not to halt if an aggregate is completely degraded.
- If you wish to preserve the previous behavior, it is required to set
raid.timeout
option to a nonzero value deliberately for the system to shut down on the expiry of the timeout period.- Along with the option value of
raid.timeout
modification, the default option value ofraid.h.mute.timeout
will be changed from0
to 1 raid.h.mute.timeout
is a hidden option that usually can only be viewed byrun -node <node name> -command "priv set diag;rdfile /etc/registry"
command.
- Along with the option value of
sfu.psm.quiet.period
Adjust the quiet time when the IOM firmware of the disk shelf is updated. Refer to BUG 1409547 for the used sample.sis.ads_optimal_clog_size_in_mb
Modify change log threshold value in MBs.sis.auto_block_share_workers
Options for interworking with the ADS function. NOTE: ADS -Automatic Dedupe Scheduling. - Volumes are configured with auto policy by default and the system automatically schedules these volumes for background dedupe processing.sis.cvbd_share_refcounted_recpt_vvbns
Option about Cross Volume background Dedupe (Allow cross vol sharing on vvbn refcounted recipients for cross volume)sis.dense_data_limit

Controlled by the command below. DO NOT use options to configure the value.

sis.savings_percent_to_deprioritize
- Change the prioritization of the system.
- If this option is set to 0, the volume will not get deprioritized due to savings issue:
::> run -node * -c options sis.savings_percent_to_deprioritize 0
