问题描述
aix下安装11g rac报错:
INS-41112 Specified network interface doesnt maintain connectivity across cluster nodes. •PRVF-6020 : Different MTU values used across network interfaces in subnet
专家解答
查看2节点相关网卡的MTU参数,发现2边不一致,
root@hxcrmdb1[/tmp] # lsattr -El en18 alias4 IPv4 Alias including Subnet Mask True alias6 IPv6 Alias including Prefix Length True arp on Address Resolution Protocol (ARP) True authority Authorized Users True broadcast Broadcast Address True monitor off Enable/Disable monitor attribute True mtu 9000 Maximum IP Packet Size for This Device True mtu_bypass off Enable/Disable largesend for virtual Ethernet True netaddr 135.10.54.220 Internet Address True netaddr6 IPv6 Internet Address True netmask 255.255.255.0 Subnet Mask True prefixlen Prefix Length for IPv6 Internet Address True remmtu 576 Maximum IP Packet Size for REMOTE Networks True rfc1323 Enable/Disable TCP RFC 1323 Window Scaling True security none Security Level True state up Current Interface Status True tcp_mssdflt Set TCP Maximum Segment Size True tcp_nodelay Enable/Disable TCP_NODELAY Option True tcp_recvspace Set Socket Buffer Space for Receiving True tcp_sendspace Set Socket Buffer Space for Sending True thread off Enable/Disable thread attribute True grid@hxcrmdb2:/oracle/grid$lsattr -El en18 alias4 IPv4 Alias including Subnet Mask True alias6 IPv6 Alias including Prefix Length True arp on Address Resolution Protocol (ARP) True authority Authorized Users True broadcast Broadcast Address True monitor off Enable/Disable monitor attribute True mtu 1500 Maximum IP Packet Size for This Device True mtu_bypass off Enable/Disable largesend for virtual Ethernet True netaddr 135.10.54.221 Internet Address True netaddr6 IPv6 Internet Address True netmask 255.255.255.0 Subnet Mask True prefixlen Prefix Length for IPv6 Internet Address True remmtu 576 Maximum IP Packet Size for REMOTE Networks True rfc1323 Enable/Disable TCP RFC 1323 Window Scaling True security none Security Level True state up Current Interface Status True tcp_mssdflt Set TCP Maximum Segment Size True tcp_nodelay Enable/Disable TCP_NODELAY Option True tcp_recvspace Set Socket Buffer Space for Receiving True tcp_sendspace Set Socket Buffer Space for Sending True thread off Enable/Disable thread attribute True
发现一个是1500,一个是9000
将节点1的9000修改为1500,然后就通过了
