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 owner 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. 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, use the remove option on the coordinator system. The system that is removed from the FlashSystem grid also needs to run the leave option.

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

  • The system must have the multiple_io_groups compatibility mode disabled, see chcompatibilitymode.
  • The system topology must be in the replication layer.
