Query output summary

  • Number of SRDF (RA) Groups — Represents the number of R1 -> R21 SRDF groups in the composite group.
  • Symmetrix ID — Represents the Symmetrix ID of the R1 device.
  • Hop-2 Symmetrix ID — Represents the Symmetrix ID of the R21 device.
  • Hop-2 Remote Symmetrix ID — Represents the Symmetrix ID of the R2 device.
  • SRDF (RA) Group Number — Represents the SRDF group of the R1 device.
  • Hop-2 SRDF (RA) Group Number — Represents the SRDF group of the R21 device.
  • Total — Sums the invalid tracks (and MB) across all displayed R21 -> R2 SRDF groups (that is, it sums all hop-2 invalid tracks).
NOTE:

With an R1->R21-> R2 configuration, issuing a query -hop2 from an RDF1 composite group indicates that the query should show the relationship of the R21-> R2 device pairs. Thus the query displays the R21 device from the R1 mirror point of view (and vice versa for RDF2 CG).

To see both hops of the RDF1 or RDF2 CG that contains devices in a cascaded SRDF relationship, use the symrdf -cg query command with the -hop2 and the -detail options.
