A system administrator has set up a Virtual IO Server to manage three micropartitioned LPARs. Physical disks are attached to the Virtual IO Server which is accessed through Multipath IO.  What should the administrator know about monitoring for error conditions with virtual disks?（）

• A、Both permanent and temporary virtual hardware error messages are logged to each client partition sharing the device.
• B、Both permanent and temporary error messages for virtual hardware are logged at each occurrence on the Virtual IO Server and then propagated to the client partition.
• C、Temporary error messages for virtual hardware are logged at each occurrence on the Virtual  IO Server. Permanent error messages for virtual hardware are stored on the client partition.
• D、Temporary error messages for virtual hardware will not necessarily be propagated to the client partition. Permanent error messages for virtual hardware are only logged once on the Virtual IO Server.
