Solaris

Hi,

I have recently configured IPMP on a Solaris 10 server. Everything was working ok when I removed the network cable from interface ce0. The floating IP failed over to ce1.

Unfortunately when I plugged the network cable back into ce0 about 2 minutes later it did not come back up. Is there a hardware setting within the prom that prevents a NIC from coming back up?

Code:

ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
ce0: flags=19040803<UP,BROADCAST,MULTICAST,DEPRECATED,IPv4,NOFAILOVER,FAILED> mtu 1500 index 2
        inet 10.0.0.77 netmask ffffff00 broadcast 192.168.30.255
        groupname netgroup
        ether 0:3:ba:33:5a:59
ce1: flags=29040843<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER,STANDBY> mtu 1500 index 3
        inet 10.0.0.78 netmask ffffff00 broadcast 10.0.0.255
        groupname netgroup
        ether 0:3:ba:33:5a:5a
ce1:1: flags=21000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4,STANDBY> mtu 1500 index 3
        inet 10.0.0.142 netmask ffffff00 broadcast 10.0.0.255

Thanks

your config files are a little strange... maybe you should have a look at the ipmp admin guide...

advisable to use local-mac-address?=true under the eeprom

run the snoop command to troubleshoot. also what are the errors you see in the messages file?

Hi,

I have used the setting local-mac-address=true. I also rebooted after setting this.

# eeprom | grep local
local-mac-address?=true

I can ping the failed interface. I reckon it's just that the in.mpathd daemon has failed this interface and failed to repair it. I'm just wondering if there is a way to manually repair it and bring it back online. I have a call logged with Sun on this one as well. Thanks.

kindly post your /etc/hosts file

# more /etc/hosts

127.0.0.1 localhost
10.0.0.142 hostname.eu.domain.com hostname loghost
10.0.0.77 dummy1 #Multipathing Test Address
10.0.0.78 dummy2 #Multipathing Test Address

as allready mentioned in my first post, your configfile with "- failover + failover" is a little strange. please stuck to the adminguide!
