Which is a benefit of dynamic tracking of Fibre Channel devices?

The correct answer is B. SAN changes are automatically detected. Dynamic tracking of Fibre Channel devices in AIX allows the system to automatically detect and reflect changes in the SAN topology without manual reconfiguration or reboots.

Question

Which is a benefit of dynamic tracking of Fibre Channel devices?

Options

  • AI/O failures are prevented with Fibre Channel tape devices.
  • BSAN changes are automatically detected.
  • CSAN disk arrays are created with a common set of disk attributes.
  • DNPIV support is added for all AIX Fibre Channel adapters.

Why each option

Dynamic tracking of Fibre Channel devices in AIX allows the system to automatically detect and reflect changes in the SAN topology without manual reconfiguration or reboots.

AI/O failures are prevented with Fibre Channel tape devices.

Preventing I/O failures with Fibre Channel tape devices is a function of error recovery and reservation policies, not dynamic tracking.

BSAN changes are automatically detected.Correct

Dynamic tracking continuously monitors the Fibre Channel SAN fabric for topology changes such as device additions, removals, or path modifications. When changes occur, AIX automatically updates the Object Data Manager (ODM) device configuration, eliminating the need for manual cfgmgr runs to recognize new or altered SAN devices.

CSAN disk arrays are created with a common set of disk attributes.

Creating disk arrays with a common set of attributes is a storage management task unrelated to the dynamic tracking feature.

DNPIV support is added for all AIX Fibre Channel adapters.

NPIV (N-Port ID Virtualization) support is a separate Fibre Channel adapter capability that is not enabled or added by dynamic tracking.
