Sep 18 17:44:25 linux-ftvo kernel: sd 10:0:0:7: queueing MODE_SELECT command. Reproducible: Always Steps to Reproduce: 1. Present 30 Volumes to host and configure dm devices for these volumes 2. Start I/O 3. Fail all the paths to one of the controller. 4. Wait for failover to complete 5. Make the paths up of the above mentioned controller to start failback.
