Cross Failover mean 2 VTL server with Failover configured take over each other in special situation. At this time, Failover status of 2 VTL server are all 2-READY. Concrete phenomenon is like below:
1. In VTL console navigation tree, icons of 2 VTL servers in Failover group are all in red color.
2. Log 2 VTL server of Failover group with SSH tool, check Failover status with sms command, FailOverStatus parameter of 2 VTL server are all 2-(READY).
Step 1 in VTL console navigation tree, right click one a VTL server in Failover group, select failover>stop take over Failover－B.
Step 2 click Yes in dialog of Virtual Tape Library console popped up, VTL server named Failover－B would restart, please wait about 4 minutes until VTL server finish start.
Step 3 check status of Failover－B server with vtl status command and sms command. All module status is OK with vtl status command, FailOverStatus parameter is 1(up) with sms command, VTL server named Failover－B recovery succeed.
Step 4 right click on VTL server named Failover－B which recover successfully, select failover > stop take over Failover－A to recover another VTL server.
Step 5 wait about 3～5 minutes, execute step 3 to verify whether VTL server named Failover－A recover successfully.
2 VTL server Failover－A and Failover－B configure Failover, Failover－A faults, Failover－B would take over service of Failover－A automatically, then Failover－A resume back to normal, Failover－B do not switch service back to Failover－A.
If Failover－B fault at this time, Failover－A cannot take over service of Failover－B, after Failover－B resume back to normal, there is Cross Failover of 2 VTL servers.
Failover－A and Failover－B is name of VTL server, please use actual name.
