The CX400 shows SPA as unmanaged and SPB as managed, in Navisphere Manager. Explain the cause of the problem.

A.
SPA is not in the correct Storage Group.

B.
SPA is not in the correct RAID Group.

C.
SPA is not properly cabled to the Fibre Channel SA.

D.
SPA is not properly cabled to the Ethernet LAN.

Explanation:
For Navisphere Manager to communicate with the array an SP must have a valid IP address, gateway, and subnet mask. Navisphere Manager is a browser-based application and relies on Ethernet connectivity to manage storage arrays. Answer A is incorrect because membership is a RAID Group has no effect on the management of the SP. Answer B is incorrect because membership is a RAID Group has no effect on the management of the SP, either. Answer D is incorrect because SAN membership occurs using WWNs and should not affect Ethernet connectivity.
