Caution:
Changing these values from their factory defaults changes the behavior of the
arbitrated loop, which can have disastrous consequences. Do not change these values
unless you have good reason to do so. Setting both threshold and interval number to 1
disables automatic port bypass.
Renaming the Hub Manager
The hub manager’s name is used in certain commands and by host-initiated connections.
This name must be different from all other hub names on the same local network.
Using the command-line interface, a user with administrator privilege can replace the
default hub manager name, as follows:
Server>>define server name
newname
where
newname
is a string of 1 to 47 letters or numerals, in any combination. The default
is DHMxxxxxx, where xxxxxx is the last six digits of the MAC address without the
dashes.
