Dell EMC Solutions Enabler 9.2 SRDF Family CLI User Guide

Syntax

You can use createpair to set the SRDF replication mode when you create SRDF device pairs.

symrdf createpair (-file option) syntax shows the syntax of createpair.

Alternatively, use symrdf set to set or modify the SRDF replication mode for a device group, a composite group, or for devices listed in a device file.

To set the mode on a device group, composite group, storage group, and device file:

symrdf -g DgName set mode Mode
symrdf -cg CgName set mode Mode
symrdf -sg SgName set mode Mode -sid SID -rdfg GrpNum
symrdf -f[ile] FileName set mode Mode -sid SID -rdfg GrpNum

Options for Mode

Sets the device pairs into synchronous mode.

semi

Sets the device pairs into semi-synchronous mode.

acp_disk
