Dell EMC Solutions Enabler 9.2 SRDF Family CLI User Guide

You can enable consistency for SRDF/A device pairs in a device group, storage group, or devices in a device file.

Syntax

symrdf -g DgName -sid SID -rdfg GrpNum  enable
symrdf -sg SgName -sid SID -rdfg GrpNum enable
symrdf -file Filename -sid SID -rdfg GrpNum  enable

To use the -file Filename option:

• All device pairs in that SRDF group must be in the device file.
• If the device file includes concurrent devices, only the R2 side specified by the -sid SID -rdfg options is enabled.

  The device group on the second R2 side is not enabled.

To use the -g DgName option:

• All device pairs in that SRDF group must be in the device group.
• If the device group includes concurrent devices, only the R2 side specified by the -sid SID -rdfg option is enabled.

Restrictions

Because you must enable consistency for each R2 mirror separately in a concurrent relationship, you cannot use the -rdfg all option.

Examples

To enable consistency protection for SRDF/A pairs in device group prod:

symrdf -g prod enable

To enable consistency protection for SRDF/A pairs listed in device file devfile1:

symrdf -file devfile1 -sid 123 -rdfg 10 enable

To enable consistency for devices in device file FileOne:

symrdf -f FileOne -sid 123 -rdfg 55 enable

To enable consistency for R2 devices in a concurrent configuration (SRDF group 56 and SRDF group 57) of devgroup2 :

symrdf -g devgroup2 -rdfg 56 enable

symrdf -g devgroup2 -rdfg 57 enable
