Everything is clear now.

Under CAM, map initiators to hosts, and map hosts to volumes. The so-call host is just a name to connect initiators (FC ports) to the disk volumes.

initiators <> hosts <> volumes

Thanks everyone again!

NAME
ypxfr -- get a YP map from YP server SYNOPSIS
ypxfr [-bcf] [-d domain] [-h host] [-s domain] [-C tid prog ipadd port] mapname DESCRIPTION
ypxfr is the utiliy in YP that transfers maps to the local host. Since the YP master transfers a map when it has changed, an YP slave should check for missed maps regulary. This can be done via an entry in crontab(5). The scripts ypxfr_1perhour, ypxfr_2perday and ypxfr_1perday could be used for that. The options are as follows: -b Preserve the entry in the database informing a YP server to use DNS to get information about unknown hosts. This option will only have effect on the two maps hosts.byname and hosts.byaddr. -c Don't send a "Clear current map" to local ypserv process. Useful if ypserv isn't running localy to avoid timeout message. -f Force map transfer, even if version of master is older than local copy. -d domain Don't use default domain, use the specifiyed domain. -h host Get map from host insteed of the maps master host. -s domain Specify a source domain other than the target domain. -C tid prog ipadd port This option is only used by ypserv. This is to open communication with an yppush on another host. FILES
