Chapter 2 — Architecture Overview
World Wide Names for Fibre Channel Drives As part of providing network
connectivity, the drive sled firmware assigns a location‐based WWN for
the drive it houses. This WWN is displayed on the Drive Details screen and
can be used by the host software to address the drive. Because this WWN is
location‐based, it remains constant even if a drive is replaced by a different
one of the same type. The new drive assumes the location‐based BlueScale
identifier and WWN.

VAILABILITY
In high‐availability enterprise environments, keeping the library operating
even in the event of a network connection failure or component failure is
extremely important. The following sections describe the high‐availability
features of the T950V library.

Note:
The WWN displayed on the Drive Details screen is actually the
WWPN for port A on the drive sled. The WWPN for port B is the
same as the one for port A except that the second digit from the
left is 2 instead of 1.
