Oracle Database 18c/19c: "-Networks" Parameter for cluvfy
In this blog I tell you, how do you specify, how to specify the settings for cluvfy run for -networks parameter.
this parameter is used to tell which all networks are going to perform what tasks in you cluster install.
An example as below.
./runcluvfy.sh stage -pre crsinst -n MUMR1DB001,MUMR1DB002 -r 18 -networks "bond0.111"[:1[PUBLIC]]/"bond2" -osdba dba -osoper dba -orainv dba -asm -presence local -asmgrp dba -asmdev /dev/oracleasm/disks/OCR_VOTE1,/dev/oracleasm/disks/OCR_VOTE2,/dev/oracleasm/disks/OCR_VOTE3 -crshome /opt/oracle/product/180/grid -fixup -verbose
In this example
-networks is
"bond0" - ethernet name
:1 - Subnet ID
PUBLIC - Type of Interface
then a \ is a seperator
finally bond2 is the second interface (will be taken as private by the cluvfy)
For 18c: cluvfy Reference see below address.
