The correct answer is B. All drives would be accessible as IBM provides control paths via the tape devices meaning. See the full explanation below for the reasoning.
Question
The exhibit shows a non-IBM tape library setup, where Fabric A, in addition to controlling tape drives 1 through 3, also controls the tape library controller. In the event of Fabric A loss, all control between host and library would be lost and all drives become inaccessible. With an equivalent IBM library, in the event of Fabric A failure, which drives would be affected?
Options
- AAll drives would be inaccessible, as the only path to the controller is lost
- BAll drives would be accessible as IBM provides control paths via the tape devices meaning
- CAll drives would be accessible due to the redundant control path on Fabric B (all IBM libraries
- DDrives 1 through 3 would be inaccessible, but drives 4-6 would continue to function due to the
