Solution 2238616.1 : OVCA ILOM IP address is not accessible

Applies to:

Oracle Virtual Compute Appliance X4-2 Hardware - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.

Symptoms

Oracle Virtual Compute Appliance node ILOM is not accessible on all the OVCA nodes. Pinging the ILOM ip address will not work:

[root@ovcamn05r1 ~]# ping 192.XX.X.XX
PING 192.XX.X.XX (192.XX.X.XX) 56(84) bytes of data.
From 192.XX.X.XX icmp_seq=2 Destination Host Unreachable
From 192.XX.X.XX icmp_seq=3 Destination Host Unreachable
From 192.XX.X.XX icmp_seq=4 Destination Host Unreachable

1.) ILOM is accessible through ipmitool, We can see the network information from the ipmitool output below, where no IP address is set on the ILOM network interface:

[root@ovcacnXX ~]# ipmitool sunoem cli 'show /SP/network'
Connected. Use ^D to exit.
-> show /SP/network

/SP/network
Targets:
interconnect
ipv6
test

Properties:
commitpending = (Cannot show property)
dhcp_clientid = none
dhcp_server_ip = (none)
ipaddress = 0.0.0.0
ipdiscovery = dhcp
ipgateway = 0.0.0.0
ipnetmask = 0.0.0.0
macaddress = 00:10:E0:76:0C:85
managementport = NET0
outofbandmacaddress = 00:10:E0:76:0C:84
pendingipaddress = 0.0.0.0
pendingipdiscovery = dhcp
pendingipgateway = 0.0.0.0
pendingipnetmask = 0.0.0.0
pendingmanagementport = NET0
sidebandmacaddress = 00:10:E0:76:0C:85
state = enabled

2.) Restarting ILOM does not resolve the issue.

Cause

The ILOM is configured to get its network configuration via DHCP. So the DHCP service needs to be up and running on the management node.

Solution

We should validate that dhcpd is up and running in management node.

[root@ovcamnXX ~]# service dhcpd status
dhcpd is stopped

Starting dhcpd service on the management node will resolve the issue.

[root@ovcamnXX ~]# service dhcpd status
dhcpd (pid 1871251) is running...

We can see the network configuration after we start the DHCP service

-> show /SP/network

/SP/network
