I have recently deployed a new ODA with last version 19.14 at customer side, and we could face an interesting failure deploying the appliance, which I would like to share with you.<\/p>\n
<\/p>\n
After reimaging the ODA and configuring the network interface with configure-firstnet, we created the appliance :<\/p>\n

And we faced following failure :<\/p>\n

During the grid installation, the check with ssh connection is not working, because, as per the logs, there is no known hosts key.<\/p>\n
This is confirmed, the process did not configure it. No known_hosts file is present :<\/p>\n
\n[root@oak ~]# cd .ssh\/\n\n[root@oak .ssh]# ll\ntotal 0\n[root@oak .ssh]#\n<\/pre>\n<\/br><\/p>\n
Solution<\/h3>\n
Let’s run a ssh locally on the ODA :<\/p>\n
\n[root@oak .ssh]# ssh ODA01\nFIPS mode initialized\nThe authenticity of host 'ODA01 (10.20.30.122)' can't be established.\nECDSA key fingerprint is SHA256:i2p0EBIgtEAYDJCF3pWhD2Fe6ITkcdiBnkT4u0BwC3s.\nECDSA key fingerprint is SHA1:o2TSYrpKihq47VJ5NUH0BnLgkFM.\nAre you sure you want to continue connecting (yes\/no)? y\nPlease type 'yes' or 'no': yes\nWarning: Permanently added 'ODA01,10.20.30.122' (ECDSA) to the list of known hosts.\nroot@ODA01's password:\nLast failed login: Wed Mar 9 17:01:42 CET 2022 on ttyS0\nThere was 1 failed login attempt since the last successful login.\nLast login: Wed Mar 9 12:34:15 2022\n[root@ODA01 ~]#\n<\/pre>\n<\/br><\/p>\n
We have now a known_hosts file and an appropriate key :<\/p>\n
\n[root@oak .ssh]# more known_hosts\nODA01,10.20.30.122 ecdsa-sha2-nistp256 AAAAE2VjZHNhLXNoYTItbmlzdHAyNTYAAAAIbmlzdHAyNTYAAABBBCor\/4ewamjVk65VB0YJnxElNKPKXOMAsoSmVdc7jS7YMGJXplmY92rRObgV0s4oYp\nztPnWuqSKPdJwt5mavY+0=\n[root@oak .ssh]#\n<\/pre>\n<\/br><\/p>\n
We can now cleanup the previous failed appliance installation :<\/p>\n
\n[root@ODA01 ~]# perl \/opt\/oracle\/oak\/onecmd\/cleanup.pl\nINFO: Log file is \/opt\/oracle\/oak\/log\/ODA01\/cleanup\/cleanup_2022-03-09_12-37-02.log\n\nINFO: Log file is \/opt\/oracle\/oak\/log\/ODA01\/cleanup\/dcsemu_diag_precleanup_2022-03-09_12-37-02.log\n\nINFO: *******************************************************************\nINFO: ** Starting process to cleanup provisioned host ODA01 **\nINFO: *******************************************************************\nINFO: Default mode being used to cleanup a provisioned system.\nINFO: It will change all ASM disk status from MEMBER to FORMER\nDo you want to continue (yes\/no) : yes\n...\n...\n...\n<\/pre>\n<\/br><\/p>\n
Curiously a cleanup of the appliance will now as well remove all the network configuration :<\/p>\n
\n[root@oak ~]# ip addr sh\n1: lo: mtu 16436 qdisc noqueue state UNKNOWN group default qlen 1000\n link\/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00\n inet 127.0.0.1\/8 scope host lo\n valid_lft forever preferred_lft forever\n2: p7p1: mtu 1500 qdisc mq master btbond1 state UP group default qlen 1000\n link\/ether e4:3d:1a:d4:b5:d0 brd ff:ff:ff:ff:ff:ff\n3: p7p2: mtu 1500 qdisc mq master btbond1 state UP group default qlen 1000\n link\/ether e4:3d:1a:d4:b5:d0 brd ff:ff:ff:ff:ff:ff\n4: em1: mtu 1500 qdisc mq state DOWN group default qlen 1000\n link\/ether a8:69:8c:0c:91:14 brd ff:ff:ff:ff:ff:ff\n5: bond0: mtu 1500 qdisc noop state DOWN group default qlen 1000\n link\/ether c6:6a:3e:ed:ad:8f brd ff:ff:ff:ff:ff:ff\n6: btbond1: mtu 1500 qdisc noqueue state UP group default qlen 1000\n link\/ether e4:3d:1a:d4:b5:d0 brd ff:ff:ff:ff:ff:ff\n7: priv0: mtu 1500 qdisc noqueue state UNKNOWN group default qlen 1000\n link\/ether aa:d8:c4:5e:f3:aa brd ff:ff:ff:ff:ff:ff\n inet 192.168.16.24\/28 scope global priv0\n valid_lft forever preferred_lft forever\n<\/pre>\n<\/br><\/p>\n
This is certainly due to the fact that since a few last version, a pubnet bridge interface is created on the bonding interface during the appliance creation. <\/p>\n
In any case all the network configuration is gone, so let’s create it again with configure-firstnet before creating the appliance again :<\/p>\n
\n[root@oak ~]# \/opt\/oracle\/dcs\/bin\/odacli configure-firstnet\nSelect the Interface to configure the network on (btbond1) [btbond1]:\nConfigure DHCP on btbond1 (yes\/no) [no]:\nINFO: You have chosen Static configuration\nUse VLAN on btbond1 (yes\/no) [no]:yes\nConfigure VLAN on btbond1, input VLAN ID [2 - 4094] 205\nINFO: using network interface btbond1.205\nEnter the IP address to configure : 10.20.30.122\nEnter the Netmask address to configure : 255.255.255.0\nEnter the Gateway address to configure [10.20.30.1] :\nINFO: Restarting the network\nINFO: Restarting the DCS agent\n<\/pre>\n<\/br><\/p>\n
