This note lists common causes of ASM start up failure with the following error on non-first node (second or others):

alert_<ASMn>.log from non-first node

DETAILS

Case1: link local IP (169.254.x.x) is being used by other adapter/network

Symptoms:
$GRID_HOME/log/<nodename>/alert<nodename>.log
[/ocw/grid/bin/orarootagent.bin(4813)]CRS-5018:(:CLSN00037:) Removed unused HAIP route: 169.254.95.0 / 255.255.255.0 / 0.0.0.0 / usb0
OS messages (optional)
Dec 6 06:11:14 racnode1 dhclient: DHCPREQUEST on usb0 to 255.255.255.255 port 67
Dec 6 06:11:14 racnode1 dhclient: DHCPACK from 169.254.95.118
ifconfig -a
usb0 Link encap:Ethernet HWaddr E6:1F:13:AD:EE:D3
inet addr:169.254.95.120 Bcast:169.254.95.255 Mask:255.255.255.0
..

Note: it's usb0 in this case, but it can be any other adapter which uses link local
Solution:

Link local IP must not be used by any other network on cluster nodes. In this case, an USB network device gets IP 169.254.95.118 from DHCP server which disrupted HAIP routing, and solution is to black list the device in udev from being activated automatically.

Dell iDRAC service module may use link local, engage Dell to change the subnet.

On Sun T series, by default, ILOM (adapter name usbecm0) uses link local, engage Oracle Support for advice.

Case2: firewall exists between nodes on private network (iptables etc)

No firewall is allowed on private network (cluster_interconnect) between nodes including software firewall like iptables, ipmon etc

Case3: HAIP is up on some nodes but not on all

Symptoms:
alert_<+ASMn>.log for some instances
Cluster communication is configured to use the following interface(s) for this instance
10.1.0.1
alert_<+ASMn>.log for other instances
Cluster communication is configured to use the following interface(s) for this instance
169.254.201.65

Note: some instances is using HAIP while others are not, so they can not talk to each other
Solution:
The solution is to bring up HAIP on all nodes.

To find out HAIP status, execute the following on all nodes:
$GRID_HOME/bin/crsctl stat res ora.cluster_interconnect.haip -init
If it's offline, try to bring it up as root:
$GRID_HOME/bin/crsctl start res ora.cluster_interconnect.haip -init
If HAIP fails to start, refer to Note 1210883.1 for known issues. Once HAIP is restarted, ASM/DB instances need to be restarted to use HAIP; if OCR is on ASM DG, GI needs to be restarted.
If the "up node" is not using HAIP, and no outage is allowed, the workaround is to set init.ora/spfile parameter cluster_interconnect to the private IP of each node to allow ASM/DB to come up on "down node". Once a maintenance window is planned, the parameter must be removed to allow HAIP to work.
The following article may assist in determining the reason for the failure to start HAIP:
note 1640865.1 - Known Issues: Grid Infrastructure Redundant Interconnect and ora.cluster_interconnect.haip
If the issue happened in the middle of GI upgrade, refer to:
note 2063676.1 - rootupgrade.sh fails on node1 as HAIP was not starting from old home but starting from new home

Case4: HAIP is up on all nodes but some do not have route info

Symptoms:
alert_<+ASMn>.log for all instances
Cluster communication is configured to use the following interface(s) for this instance
169.254.xxx.xxx
"netstat -rn" for some nodes (surviving nodes) missing HAIP route
netstat -rn
Destination     Gateway         Genmask         Flags   MSS Window irtt Iface
161.130.90.0     0.0.0.0         255.255.248.0   U         0 0          0 bond0
160.131.11.0     0.0.0.0         255.255.255.0   U         0 0          0 bond2
0.0.0.0      160.11.80.1     0.0.0.0         UG        0 0          0   bond0

The line for HAIP is missing, i.e:

169.254.0.0     0.0.0.0         255.255.0.0     U         0 0          0 bond2

Note: As HAIP route info is missing on some nodes, HAIP is not pingable; usually newly restarted node will have HAIP route info
Solution:
The solution is to manually add HAIP route info on the nodes that's missing:

4.1. Execute "netstat -rn" on any node that has HAIP route info and locate the following:

169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 bond2

Note: the first field is HAIP subnet ID and will start with 169.254.xxx.xxx, the third field is HAIP subnet netmask and the last field is private network adapter name

4.2. Execute the following as root on the node that's missing HAIP route:
# route add -net <HAIP subnet ID> netmask <HAIP subnet netmask> dev <private network adapter>

i.e.

# route add -net 169.254.0.0 netmask 255.255.0.0 dev bond2
4.3. Start ora.crsd as root on the node that's partial up:.
# $GRID_HOME/bin/crsctl start res ora.crsd -init
The other workaround is to restart GI on the node that's missing HAIP route with "crsctl stop crs -f" and "crsctl start crs" command as root.

Case5. HAIP is up on all nodes and route info is presented but HAIP is not pingable

Symptom:
HAIP is presented on both nodes and route information is also presented, but both nodes can not ping or traceroute against the other node HAIP.

Solution:
For Openstack Cloud implementation, engage system admin to create another neutron port to map link-local traffic. For other environment, engage SysAdmin/NetworkAdmin to review routing/network setup.
