PRVG-1101 : SCAN name "rac-scan" failed to
resolve - Cause: An attempt to resolve specified SCAN name to a
list of IP addresses failed because SCAN could not be resolved in DNS or GNS
using 'nslookup'. - Action: Check whether the specified SCAN name
is correct. If SCAN name should be resolved in DNS, check the configuration of
SCAN name in DNS. If it should be resolved in GNS make sure that GNS resource
is online.

PRVF-4657 : Name resolution setup check for
"rac-scan" (IP address: 192.168.56.12) failed - Cause:
Inconsistent IP address definitions found for the SCAN name identified using
DNS and configured name resolution mechanism(s). - Action: Look up
the SCAN name with nslookup, and make sure the returned IP addresses are
consistent with those defined in NIS and /etc/hosts as configured in
/etc/nsswitch.conf by reconfiguring the latter. Check the Name Service Cache
Daemon (/usr/sbin/nscd) by clearing its cache and restarting it.
Check Failed on Nodes: [rac2,
rac1]

PRVF-4664 : Found
inconsistent name resolution entries for SCAN name "rac-scan" -
Cause: The nslookup utility and the configured name resolution
mechanism(s), as defined in /etc/nsswitch.conf, returned inconsistent IP
address information for the SCAN name identified. - Action: Check
the Name Service Cache Daemon (/usr/sbin/nscd), the Domain Name Server (nslookup) and the /etc/hosts file to make sure the IP
address for the SCAN names are registered correctly.
