Dell EMC Solutions Enabler 9.2 SRDF Family CLI User Guide

Syntax

To display detailed information about the second hop SRDF pair of a cascaded SRDF relationship, use the -detail option with the symrdf query command.

Detailed output displays the association of the cascaded pair with the appropriate local pair.

Example

To display detailed information about the second hop SRDF pair of a cascaded SRDF relationship for composite group testcg:

symrdf query -cg testcg -rdfg name:name1 -hop2 -detail

Query output information

• Symmetrix ID — Represents the Symmetrix ID of the R1 device if outside a Hop-2 {. . .} group, or the Symmetrix ID of the R21 device if inside a Hop-2 {. . .} group.
• Remote Symmetrix ID — Represents the Symmetrix ID of the R21 device if outside a Hop-2 {. . .} group, or the Symmetrix ID of the R2 device if inside a Hop-2 {. . .} group; had this been an RDF2 CG, then Remote Symmetrix ID inside a Hop-2 {. . .} group would represent the Symmetrix ID of the R1 device.
• SRDF (RA) Group Number — Represents the SRDF group from the R1->R21 devices if outside a Hop-2 {. . .} group, or the SRDF group from the R21->R2 devices if inside a Hop-2 {. . .} group; had this been an RDF2 CG, then SRDF (RA) Group Number inside a Hop-2 {. . .} group would represent the SRDF group from the R21->R1 devices.
