We have a tape san and a disk san. The tape san consists of a 24k with stk 9840c tape drives and win2k3 and AIX 5.3 servers attached. In this environment, there is no zoning as the backup software shares the drives among the servers.

What I mean by high enc out count, I mean that before the backups run, we clear out the port error counters. We then run the backups, we then observe that when enc out errors start to increase quickly, we notice that performance goes in the tank. The problem can be seen across different ports and different server types.
