Solution 1935504.1 : Error when Running bdacheckib on Oracle Big Data Appliance during Installation of "bdacheckibx: entry for switch bda-01sw-ib1 not found in iblinkinfo output"

Applies to:

Big Data Appliance X4-2 Hardware - Version All Versions and later
Linux x86-64

Symptoms

The bdacheckib utility looks for lowercase switch names like bda-01sw-ib1 as per the output below. However in the case here, the switch names were entered into the BDA Configuration Utility in uppercase like BDA-01sw-ib1. The uppercase names show in the BDA Install Review page.

[root@bda-01-bda01 bda]# bdacheckib
bdacheckibx: entry for switch bda-01sw-ib1 not found in iblinkinfo output
bdacheckibx: entry for switch bda-01sw-ib2 not found in iblinkinfo output
bdacheckibx: entry for switch bda-01sw-ib3 not found in iblinkinfo output
bdacheckib: out of 0 servers of interest accessible

You can verify the uppercase switch names with the iblinkinfo output below:

[root@bda-01-bda01 bda]# iblinkinfo
CA: SUN IB QDR GW switch BDA-01sw-ib3 10.***.*.** Bridge 0:

Cause

Hostnames for hosts, switches, PDUs, etc. created in uppercase but all should be in lowercase.

Solution

1. Change the hostnames in the switch configuration to lowercase. Do so by logging into the switches and configuring the hostnames in the switches with lowercase.

See the documentation links below for more information:

Cisco switch: http://docs.oracle.com/cd/E55905_01/doc.40/e55796/configure.htm#BIGOG76698

Changing the the InfiniBand Leaf and Spine Switches hostnames:
http://docs.oracle.com/cd/E55905_01/doc.40/e55796/configure.htm#BIGOG76612

See page 15-17 in the EIS Checklist for X4-2 for logging in and changing hostname in Cisco Switch.

See page 24 in the EIS Checklist for X4-2 for changing the SUN DATACENTER 36-PORT MANAGED QDR INFINIBAND GATEWAY SWITCHES hostnames.

See page 32 and 33 in the EIS Checklist for X4-2 for changing the spine switch.

2. Change the hostnames for all the BDA hosts including hosts, switches, and PDUs to lowercase using the BDA Configurator.

3. Reboot the switches and servers after the changes are made.

4. Copy the newly generated BdaDeploy.json to the nodes:

a. Backup the current copy of /opt/oracle/bda/BdaDeploy.json on Node 1 as 'root' user.

# cp /opt/oracle/bda/BdaDeploy.json /opt/oracle/bda/BdaDeploy.jsonORIG

b. Copy the newly generated BdaDeploy.json to /opt/oracle/bda/ on Node 1.

c. Replace the old /opt/oracle/bda/BdaDeploy.json with the new one on all nodes with the following command. Do this on Node 1 as 'root' user.

# dcli -C -f /opt/oracle/bda/BdaDeploy.json -d /opt/oracle/bda/BdaDeploy.json

5. Run bdacheckib with no arguments to confirm it now runs successfully.

# bdacheckib
