3c6e85 |
When loop was made down explicitly due to cable pull, then for N2N toplogy,
|
|
|
3c6e85 |
if FAWWPN BIT is enabled by user, then it would restore some default
|
|
|
3c6e85 |
(garbage) value for Physical port WWPN, so this show garbage WWPN for the
|
|
|
3c6e85 |
port. Fix is, to restore physical port WWPN, if it is fabric
|
|
|
3c6e85 |
configuration. When loop is explicitly made down, and FAWWPN feature is
|
|
|
3c6e85 |
enabled, then driver need to restore original flashed WWPN.
