Setting Grid Properties

After you add a Grid, you can generate its Join Key file as described in /wiki/spaces/mgmadminguide/pages/911183060.

   From Grids -> List tab, select the Grid and click the Edit icon.

   Note

   • The Join Key, Join Key File, and Grid Master IP Address/ FQDN fields depends on the Master Grid communication mode selected while creating the Multi-Grid Master. For information on creating a Multi-Grid Master, see /wiki/spaces/mgmadminguide/pages/911181866.

   • Name: You can change the Grid name.
   • Join Key: You can make the following changes:

     • MGM Initiated: You can type or paste the join key generated by the Grid. This is required to decrypt the join key file.
   • Expiration: Click on Generate to generate the join key file and join key details, this field displays the date and time for which the generated join key file and join key combination is valid.     
   • Join Key File: You can make the following changes:

   • Comment: Optionally, enter additional information about the Grid.
   • Strict Delegation Mode: Select this option to restrict the address space within which the Grid admins can create networks. If the Master Grid admin allocates an address block to the Grid, then the admins of the Grid can create networks within and below the address block.
   • Grid Master IP Address/ FQDN: You can make the following changes:
   • sub Grid Initiated: Displays the IP address of the Grid when it is joined to a Master Grid. You can change it to FQDN.
   • MGM Initiated: Displays the IP address of the Grid when it is joined to a Master Grid. It is mandatory to enter the details.
   • Attach Port: Displays the attach port number when a Grid is joined to a Master Grid. The default value of attach port is 21195.
     You need to manually update the Grid Master IP Address/ FQDN field in the Multi-Grid Manager in the following scenarios:
     • Modify Grid Master IP when Grid is detached
     • Promote a Grid master candidate when Grid is detached
     • When Grid is behind a NAT device
     • When MGMT interface is used for MGM initiated mode, Master Grid communication for a Grid connected through a LAN interface.
