I have an SP High node running AIX 4.1.5 with two token ring adapters.
The adapters are type 8-S.
tr0 is the live adapter and tr1 is a backup. Should tr0 fail, I want to
transfer the MAC address to tr1 as well as the IP address.
However, I've got stuck on the first step : giving tr0 an alternate MAC
address. I set the MAC address with the command
chdev -l tok0 -a use_alt_addr=yes -a alt_addr='0x0001DEADBEEF'
This command is successful. However, when I try to bring the interface
back up with the command 'ifconfig tr0 up' I get the following error :
'0821-510 ifconfig : error calling entry point for /usr/lib/drivers/if_tr
- cannot establish a connection to a remote service'.
I've looked up this error in info and it gives several possible reasons
(e.g. root filesystem full, adapter added after IPL) none of which apply
in this case. When I remove the alternative MAC address, the adapter
comes up fine.
Can anyone tell me where I am going wrong? (by email please)
