1) Migration du port sx25a0 de hdlc0 vers hdlc1 : Il faut : -Sauvegarder l'ensemble des paramètres du port x25 : par exemple : lsattr -El sx25a0 > /tmp/oldsx25a0param.txt -Supprimer le port sx25a0 :rmdev -dl sx25a0 -Recréer le port sx25a0 via smitty sur hdlc1 -Récupérer ses paramètres actuels : lsattr -El sx25a0 > /tmp/newsx25a0param.txt et comparer les deux fichiers .txt -Pour chaque différence , corriger le paramètre pour le nouveau port via la commande chdev : chdev -l sx25a0 -a NOM_DU_PARAMETRE=VALEUR_DU_PARAMETRE

2) Inversion des cables au niveau du serveur . Il n'y a pas de commandes particulières mais je conseille d'intervertir les cables à froid (donc machine éteinte) puis de simplement redémarrer le serveur .

3) Inversion des cables au niveau des modems . Dans ce cas , je pense qu'il faut : Un arrêt de l'application , rmdev -l des ports concernés , rmdev -l des hdlc concernés puis mkdev -l des hdlc , mkdev -l des ports .

NB : Comme vous utilisez du X.21 (V11) , merci de vérifier que vos hdlc ont le paramètres x21_idle_char égal à 0x7e . Par exemple :

 lsattr -El hdlc0 et si besoin chdev -l hdlc0 -a x21_idle_char=0x7e

ADAPTER Specifies the adapter over which the X.25 port is configured. DRIVER Specifies the driver over which the X.25 port is configured. PORT Specifies the port name. COMIO Specifies the COMIO port name, if a COMIO emulation port is configured to this X.25 port. TCPIP Specifies the TCP/IP name, if a TCP/IP interface is configured to this X.25 port. NUA Specifies the port's network user address. LOGICAL BOARD Specifies the logical board number for the adapter. There is NOT a direct correlation between this number and the associated device driver number. LOGICAL PORT Specifies a logical port number associated with each X.25 port. With the varying number of ports available on the different supported adapters, a constant, logical number must be assumed to allow adapters to be moved physically in the system. Each adapter has a block of eight ports associated with it, though the number of port available to be configured may be less than that. PHYSICAL PORT Specifies the port being used on the adapter.
