Environment: cent0s 6.4 64bit, grid 64bit
The "TCP connectivity of subnet" issue occurs during self-check.
[Problem]
Manually perform grid self-check and report the following error:

[Solution]
[[Email protected] network-Scripts] # vi ifcfg-eth0
-- Remove gateway = 192.168.56.1
Device = eth0
Onboot = Yes
Bootproto = static
Ipaddr = 192.168.56.30
Netmask = 255.255.255.0
[[Email protected] network-Scripts] # vi ifcfg-eth1
-- Remove gateway = 10.10.10.1
Device = eth1
Onboot = Yes
Bootproto = static
Ipaddr = 10.10.10.90
Netmask = 255.255.255.0
After the server is restarted, the problem does not occur again.
