the operating system driver detects and communicates with
the devices. Click the Refresh button to force a manual
refresh. Verify that the HBA tree displays the appropriate
device port name and LUN information.
■ The DNS or the local host file may contain an incorrect IP
address for the host name. Use the Ping command to ping
the host name; verify that the correct IP address is translated
from the name.
