SRDF/Star consistency group restrictions

These restrictions apply to the add and remove options of the symstar modifycg command:

  • The symstar modifycg command must be executed at the workload site.
  • All arrays are reachable.
  • The SRDF daemon must be running locally on the Star control host where the symstar modifycg command is issued.
  • The symstar modifycg command can only move devices within one SRDF/Star triangle in the CG.
  • The following options in the SRDF/Star options file must have these settings:

    SYMCLI_STAR_AUTO_DISTRIBUTE_INTERNAL_FILE=YES

    SYMCLI_STAR_COMPATIBILITY_MODE=v70

  • If the symstar modifycg command is run when one of its target sites is in the Connected state, the SRDF mode must be adaptive copy.
NOTE:

In the event the symstar modifycg command fails, you can rerun the command or issue symstar recover. No control operations are allowed on a CG until after a recover completes on that CG.
