• Question 44:

  With ALUA support, how does the storage system handle I/Os to the non-preferred path? (Choose the best answer.)

  A. The controller handles them normally, updating both controllers'cache to maintain consistency, which is why ALUA requires cache mirroring to be enabled.

  B. They are accepted but maintained in cache with a special change log, and only processed after 5 minutes when volume ownership may be changed.

  C. They are shipped over to the owning controller to be managed, then returned through the non-preferred path after completion.

  D. They are rejected with a specific SCSI check condition.

  E. The non-owning controller takes ownership of the volume in order to handle them, then restores ownership to the original controller.
