Dell EMC Solutions Enabler 9.2 SRDF Family CLI User Guide

Syntax

Use the symrdf createpair command with the ‑invalidate r1 or ‑invalidate r2 option to create devices (R1 or R2) in a new or existing configuration.

When the command completes, the pairing information is added to the SYMAPI database file on the host.

For example:

symrdf -sid 55 -file devicefile establish -rdfg 1

symrdf -sid 55 -file devicefile query -rdfg 1

Once synchronized, you can perform various SRDF operations on SRDF pairs listed in the device file.

Example

In the following example, the symrdf createpair command:

• Creates new SRDF pairs from the list of device pairs in the file devicefile.
• The -type R1 option identifies the first-column devices in the device file in array 55 as R1 type devices.
• The -invalidate r2 option indicates that the R2 devices are the targets to be refreshed from the R1 source devices.
• The -nowd option bypasses the validation check to ensure that the target of operation is write disabled to its host.
• The SRDF pairs become members of SRDF group 1.

symrdf createpair -sid 55 -file devicefile -rdfg 1 
-type R1 -invalidate r2 -nowd
