Description

This command can be used to create a new FlashSystem grid and manage the members of the FlashSystem grid. The system that creates the FlashSystem grid is referred to as the coordinator of the FlashSystem grid, and it assumes responsibility for adding and removing other systems. After creating a FlashSystem grid, the following steps must be performed in order to add a system:
  1. Check the list of scope certificates by using lssystemcertstore CLI. In case the (scope_id = 3) internal_communication certificate is present then download the certificate by using the chsystemcertstore CLI. Otherwise, download certificate by using the chsystemcertstore CLI for scope default or use chsystemcert CLI. Copy the certificate of the FlashSystem grid coordinator-system to the new system, and add it to the truststore by using the mktruststore CLI.
  2. Request to join the FlashSystem grid by using the join option. Provide the IP address or the FQDN of the coordinator system and the entry, which the coordinator system has in the truststore.
  3. Copy the certificate from the new system to the FlashSystem grid coordinator-system, and add it to the truststore.
  4. On the coordinator system, accept the request to join the FlashSystem grid by using the accept option. Provide the IP address or the FQDN of the new system and the entry, which the new system has in the truststore.

To remove a system from a FlashSystem grid by using the CLI, use the remove option on the coordinator system.

To create or join a FlashSystem grid, the following requirements must be met:

  • The system topology must be in the replication layer.

You can also use the managegrid command to change the current coordinator of the FlashSystem grid and make another member system from the grid as coordinator. For details, see Changing FlashSystem grid coordinator.

Note: This command is available during the upgrade process.

An invocation example

The following creates a new FlashSystem grid and makes this system the coordinator system.
