  • Operations Automation 7.0

Symptoms

OA Management Node should be migrated to RHEL7 per the following KB article:

#130182 Migration of OA 7.0 Premium MN from RHEL6 to RHEL7.

Migration precheck fails with the following output:

Error: Provided IPs for dst MN and MN DB are identical while src MN has remote DB. Please provide correct dst MN and MN DB IPs

However, the database is deployed on the same node.

Cause

DB connection parameters contain the Management Node's hostname as a communication address, instead of the BackNet IP address:

# grep Server /usr/local/pem/etc/odbc.ini
Servername      = core.provider.com
# grep dsn_host /usr/local/pem/etc/Kernel.conf
dsn_host=core.provider.com

Resolution

Edit the parameters above to use the Management Node's Backnet IP address:

# grep Server /usr/local/pem/etc/odbc.ini
Servername      = 192.0.2.1
# grep dsn_host /usr/local/pem/etc/Kernel.conf
dsn_host=192.0.2.1
