  • What does syslog show during the issue timeframe ? What is Veritas Version and Linux version here ?

    Not sure where did you see both the paths are disabled. The vxdisk list output shows that paths are

    enabled. Config copy disabled is not an issue since there are other disks in same diskgroup which will have Enabled config copy.

    Please open support case.

      Yes,  both the paths are showing as enabled but both are showing as secondary.

      Ideally one path shows as primary and other secondary as ita an A/P  array.

       

      how can I enable the config in one disk ?

        Enabling config copy is not going to change anything. We need to find out why it is showing as secondary for both the paths. Please open support case.
