Issue/Introduction

During server reboot cdm disk alerts are getting cleared and regenerating once server comes online.

How to stop alerts getting cleared during server reboot.This is causing duplicate tickets in ticketing system

Environment

Release : 8.51

Component : UIM - CDM WITH IOSTAT

Cause

Addtional configuration keys introduced in cdm probe to control this behaviour.

Resolution

Flag "skip_disk_clear_on_restart = true " works when we do soft restart of probe for cdm 6.30 as well as for cdm 6.42.

For example changing loglevel or configuration options in probe causes a soft restart.

Flag "skip_disk_clear_on_hardstart = true " works when cdm probe is restarted (use case could be probe restarted or robot restarted or server restarted)

From cdm probe perspective cdm probe process ID should change. This feature was not present in cdm 6.30/ 6.34 and present in CDM 6.42 only.

Note: 

Any Flags (yes , y , true , 1 ) can be used to activate these options 

To deactivate : can use "false" or "no"

Case sensitivity i.e small  or capital letters is not an issue , flags are first converted into lowercase and only then compared.

Example

(cdm 6.42 and later) skip_disk_clear_on_hardstart: Add this key manually via raw configure and set the value to true to prevent clearing of disk alarms on server restarts.

Default: false

(cdm 6.42 and later) skip_disk_clear_on_restart: Edit this key via raw configure and set the value to true to prevent clearing of disk alarms on soft restarts.

Default: false
