I´m using an active active configuration on FAS3270 controllers, using SnapVault to a secondary site for backup.
Could this affect any SnapVault relationships.
I´m using a NDMP accelerator for backup up data (to a third- site 400miles apart.)
I did change and set the options ndmpd.data_port_range 27000-27000
After that some of my snapvault relationships to my secondary FAS controller started failing. Using other IP adresses than the preferred interface for NDMP??
Also, is it Ok just to have one port as in my case above.
Because then I set it to 27000-65535, and the first backup was OK running on port 27000.
Second try failed running on port 27001, also third try on port 27002 failed.
All ports between 27000-65535 is open for traffic.
