An interface doesn't come back after a reboot.


When I rebooted a server one of the main interfaces didn't come back. it was left with 0.0.0.0

The interface that didn't come back was igb0

This is ifconfig before the reboot:


lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
igb0: flags=9040843<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER> mtu 1500 index 8
inet 10.1.19.77 netmask ffffff00 broadcast 10.1.19.255
groupname prod
ether 0:10:e0:46:67:c
igb0:1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 8
inet 10.1.19.76 netmask ffffff00 broadcast 10.1.19.255
igb1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
inet 10.2.19.76 netmask ffffff00 broadcast 10.2.19.255
ether 0:10:e0:46:67:d
igb2: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 4
inet 10.3.19.76 netmask ffffff00 broadcast 10.3.19.255
ether 0:10:e0:46:67:e
igb3: flags=9040843<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER> mtu 1500 index 7
inet 10.1.19.78 netmask ffffff00 broadcast 10.1.19.255
groupname prod
ether 0:10:e0:46:67:f
usbecm0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 6
inet 169.254.182.77 netmask ffffff00 broadcast 169.254.255.255
ether 2:21:28:57:47:17



And this is after the reboot:


lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
igb0: flags=1000842<BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet 0.0.0.0 netmask 0
ether 0:10:e0:46:67:c
igb1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
inet 10.2.19.76 netmask ffffff00 broadcast 10.2.19.255
ether 0:10:e0:46:67:d
igb2: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 4
inet 10.3.19.76 netmask ffffff00 broadcast 10.3.19.255
ether 0:10:e0:46:67:e
igb3: flags=9040843<UP,BROADCAST,RUNNING,MULTICAST,DEPRECATED,IPv4,NOFAILOVER> mtu 1500 index 5
inet 10.1.19.78 netmask ffffff00 broadcast 10.1.19.255
groupname prod
ether 0:10:e0:46:67:f
usbecm0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 6
inet 169.254.182.77 netmask ffffff00 broadcast 169.254.255.255
ether 2:21:28:57:47:17



It's Solaris 10.

Thanks for any pointers

How does the /etc/hostname.igb0 file look like?
Usually it has just a hostname entry (one word) that must exactly match in the /etc/inet/hosts file and maps to the IP address.
Compare to the other files: /etc/hostname.igb1 /etc/hostname.igb2 ...!
