Dell EMC Solutions Enabler 9.2 SRDF Family CLI User Guide

Use the symrdf list command with the -concurrent option to display concurrent SRDF devices on the local array.

Each device of a concurrent pair belongs to a different RDF group, as shown in the RDF Typ:G column.

symrdf list -concurrent -sid 321

Use the query -rdfg all command to display the state of concurrent SRDF pairs.

In the following example, concurrent SRDF pairs are in the process of synchronizing (SyncInProg):

symrdf -g conrdf query -rdfg all

During synchronization, use the symrdf verify -summary command to displays a summary message every 30 seconds until both concurrent mirrors of each SRDF pair are synchronized:

symrdf -g conrdf verify -summary -rdfg all -i 30 -synchronized
