we have AIX 5.3 nim server configured with mksysb backup through nfs. We have two NIC cards in NIM server. one card normal Normal. another one is Gigabit Ethernet. Both NICs configured with ip and working fine. from NIM server /export/mksysbs directoy has been hosted to nim clients for taking mksysb backup. From NIM client if we mount /export/mksysb directory through NIC card one(which is residing on NIM) we could able to write and it is working fine. But if access the same diretory through GIGABIT ethernet adapter ( adapter 2 which is residing on NIM server) the mount is not allowing to write saying that touch: 0652-046 Cannot create hi. I am able to access the server through NIC adapter 2 from NIM client ? Could any body help please ?
