Notes If the Activate GMC Group Promotion Schedule option is not enabled on Grid Master, and if you choose to continue with Grid Master Candidate promotion using the command, set promote_master, then the Grid Master Candidate promotion works as described in Promoting the Master Candidate. By default, all the members are part of the Default group. The Grid Master Candidate group members can be customized according to your requirement; however Grid Master Candidate cannot be customized as Grid Master Candidate is part of the Default group only. If you want to reconnect members of any group to the newly promoted Grid Master, irrespective of the scheduled time, you can click Join Group Now option, by selecting the following Join Group Now icon,  in GMC Group Promotion Schedule editor. This works only during the promotion of a Grid Master Candidate. That is, Join Group Now is activated (enabled) only during the promotion of Grid Master Candidate group; it is disabled after the scheduled time of all the groups expires after the Grid Master Candidate is promoted. For any offline member, the Join Group Now will be disabled 8 hours after the Grid Master Candidate promotion. The Add GMC Group Wizard in the GMC Group Promotion Schedule editor is available only for future schedules. The maximum scheduled time for the promotion of any Grid Master Candidate group is 8 hours. We do not recommend enabling a schedule Grid upgrade and GMC Group Promotion Schedule at the same time. The Time Zone for any group, displays the Grid Manager’s time zone, and if there are any member(s) in the group, the Time Zone automatically reflects the first group member(s) time zone. The scheduled Time displays the new time zone, if the Time Zone is modified or if a member is moved across different groups. During the Grid Master Candidate promotion, if a Grid member is offline, Grid Manager continuously attempts to connect to the offline Grid member for every 60 seconds. If the GMC Group Promotion Schedule editor is disabled after Grid upgrade, then you can unset the previously triggered Grid Master Candidate promotion, by using the CLI command set gmc_promotion forced_end. It is recommended to run this command when the Grid is completely upgraded. For more information see, set gmc_promotion.
