  • All requirements for a consistency group between one primary and one secondary system apply to a consistency group between multiple primary and secondary systems.
  • For VSP 5100 and VSP 5500, the primary and secondary systems must be VSP 5000 series, VSP G1x00, VSP F1500, or VSP, or VSP G/F350, G/F370, G/F700, G/F900, VSP E series. No other models can be used.
  • For VSP 5200 and VSP 5600, the primary and secondary systems must be VSP 5000 series or VSP E1090. No other models can be used.
  • A consistency group can consist of a maximum of four primary and four secondary (paired) systems.
  • The microcode or firmware for both primary and secondary systems must support consistency groups between multiple primary and secondary systems. If it does not, pair creation results in failure.
    • If a storage system at the primary site does not support the consistency group functionality for multiple primary and secondary storage systems, a pair for a consistency group of one primary and one secondary storage system is created.
    • If a storage system at the secondary site does not support the consistency group functionality for multiple primary and secondary storage systems, no pairs can be created.
  • You must install the CCI version that supports a consistency group containing multiple primary systems and secondary systems.
  • Pair operations can be performed only from CCI. Pair operations from Device Manager - Storage Navigator are not supported.
  • Cascade configurations with Universal Replicator pairs are not supported.
  • (VSP 5000 series) Compatible FlashCopy® configurations are not supported.
  • You can assign pair volumes that belong to multiple virtual storage machines to a consistency group consisting of multiple primary and secondary systems.
