Port WWN — Port World Wide Name of the attached node
(N_Port). The WWN is prefixed by the manufacturer’s name of
the host bus adapter that attaches to the device.
If a nickname is assigned to the WWN and Display Options is set
to Nickname, the nickname appears instead of the WWN. (Refer
to Defining Nicknames on page 4-30.)
To change a node’s display between the WWN and nickname:
a. Right-click the port’s row.
b. On the pop-up menu, move the cursor over Display Options.
c. Click the desired option on the pop-up sub-menu.
◆
Unit Type — Attached device, (if the device provides this
information):
The unit type comes directly from the device sense ID when the device
attaches to the port during login. If the connection is lost to the device,
the type appears as unspecified, since the device is no longer logged in
to the port. When the device logs back in, the unit type is updated.
◆
BB_Credit — Buffer-to-buffer credit that the attached node has
available.
