PRVG-11055 : Interfaces configured with subnet number "90.xxx.xxx.0" have multiple subnets masks
PRVG-11056 : subnet masks "255.255.254.0" are configured with subnet number "90.xxx.xxx.0" on nodes "rklx4,rklx3,rklx2,rklx1"
PRVG-11056 : subnet masks "255.255.255.0" are configured with subnet number "90.xxx.xxx.0" on nodes "rklx4,rklx3,rklx2,rklx1"
Subnet mask consistency check failed.

Result: Node connectivity check failed

SOLUTION
========

# $ORA_CRS_HOME/bin/oifcfg iflist -p -n

bond0 172.xx.xx.0 PRIVATE 255.255.255.0
bond1 90.xxx.xxx.0 UNKNOWN 255.255.254.0



# $ORA_CRS_HOME/bin/crs_stat -p ora.rklx1.vip =====> run this on all nodes of the cluster

You need to modify the subnet mask by running the following

srvctl modify nodeapps -n rklx1 -A 90.xxx.xxx.166/255.255.254.0/bond1

srvctl modify nodeapps -n rklx2 -A 90.xxx.xxx.61/255.255.254.0/bond1

srvctl modify nodeapps -n rklx3 -A 90.xxx.xxx.114/255.255.254.0/bond1

srvctl modify nodeapps -n rklx4 -A 90.xxx.xxx.133/255.255.254.0/bond1
