Dell EMC Solutions Enabler 9.2 SRDF Family CLI User Guide

Adding device pairs to an active SRDF/A session

1. Use the createpair -establish operation to create the new device pairs, add them to a temporary SRDF group (10), and synchronize:

   symrdf createpair -file Myfile -sid 1234 -rdfg 10 -type RDF1 -establish

2. Use the verify -synchronized operation to monitor synchronization:

   symrdf verify -file MyFile -sid 1234 -rdfg 10 -synchronized

   When the device pairs are synchronized:

3. Use the suspend operation to suspend the device pairs in the temporary group so they can be moved to the active SRDF/A group:

   symrdf suspend -file MyFile -sid 1234 -rdfg 10

   NOTE:

   Since the temporary group is synchronous, you cannot use the consistency exempt option.

4. Use the movepair operation with the -exempt option to move the device pairs from the temporary SRDF group to the active SRDF/A group:
   symrdf movepair -file MyFile -sid 1234 -rdfg 10 -new_rdfg 20 -exempt
5. Use the resume operation to resume the device pairs:

   symrdf resume -file MyFile -sid 1234 -rdfg 20

6. Use the verify -consistent -noinvalids operation to display when the device pairs become consistent and there are no invalid tracks on the R1 and R2 sides:
   symrdf verify -file MyFile -sid 1234 -rdfg 20 -consistent -noinvalids
   NOTE:Do not enable host access to the R1 side until the pair state for the devices reaches Consistent.
