Dell EMC Solutions Enabler 9.2 SRDF Family CLI User Guide

Setting up for a multi-hop configuration

1. Use the symdg create command to create an R1 device group (-g ) or composite group (-cg).

   symdg create newdg2 -type RDF1
   

2. Use the symdg add dev command to add any number of R1 devices.

   symdg add dev 0040 -g newdg2 -sid 0001
   

3. Use the symdg add dev command to remotely associate an equal number of matching sized R1-BCVs or Hop 1 RBCV devices.

   symbcv associate dev 01A0 -g newdg2 -rdf
   symbcv associate dev 01A1 -g newdg2 -rrdf
   

   The following must be true before you start a symreplicate session without a setup operation:

   • The local SRDF pairs must be synchronized
   • The BCV pairs must be established
   • The remote SRDF pairs must be suspended.
   • If the final BCVs in the second-hop array are used, the BCVs must be in the split state.

   Device pair state can be configured automatically using the symreplicate setup command or the -setup option with the symreplicate start command.

   Setting up pair states automatically provides more information.
