Checking daemon liveness...
Liveness check passed for "xntpd"
PRVF-5436 : The NTP daemon running on one or more nodes lacks the slewing option "slewalways yes"

PRVF-9652 : Cluster Time Synchronization Services check failed

From $ORACLE_BASE/oraInventory/logs/installActions{$TIMESTAMP}.log installation logs it shows similar entries like following:

..
INFO: Checking daemon liveness...
INFO: Liveness check passed for "xntpd"
INFO: PRVF-5436 : The NTP daemon running on one or more nodes lacks the slewing option "slewalways yes"
INFO: Clock synchronization check using Network Time Protocol(NTP) failed
INFO: PRVF-9652 : Cluster Time Synchronization Services check failed
INFO: Post-check for cluster services setup was unsuccessful on all the nodes.

Cause of the Problem
The problem happened because the time service (such as NTP) is not running or doesn't have slew option set.

Solution of the Problem
The problem happened because time service NTP is not running or doesn't have slew option set.
So, ensure that NTP service is up and running.
Based on the operating system solutions are given below.

1) Linux:
To verify service as root user issue,
# /sbin/service ntpd status
ntpd (pid 4423) is running...

Check process is running or not by.
# ps -ef|grep ntp
ntp 4209 1 0 Mar10 ? 00:00:00 ntpd -u ntp:ntp -p /var/run/ntpd.pid -x

# grep OPTIONS /etc/sysconfig/ntpd
OPTIONS="-u ntp:ntp -p /var/run/ntpd.pid -x"

If NTP service is not started then to start the service issue,
To start the service issue,

# /sbin/service ntpd start

2) Solaris:
To verify the service issue,

# /usr/bin/svcs ntp
STATE STIME FMRI
online 3:29:11 svc:/network/ntp:default

# ps -ef|grep ntp
root 21223 1 0 Mar 10 ? 0:21 /usr/lib/inet/xntpd

# grep slewalways /etc/inet/ntp.conf
slewalways yes

To start the NTP service issue,

# /usr/sbin/svcadm enable ntp

3) HP-UX:

To verify the service issue,

# ps -ef|grep ntp
root 6022 1 0 14:23:42 ? 0:01 /usr/sbin/xntpd -x

# grep XNTPD_ARGS /etc/rc.config.d/netdaemons
export XNTPD_ARGS="-x"

To start the service issue,
# /sbin/init.d/xntpd start

4) AIX:

To verify the service issue,

# /usr/bin/lssrc -ls xntpd
xntpd tcpip 368754 active

# ps -ef|grep ntp
root 786614 151686 0 08:02:32 - 0:00 /usr/sbin/xntpd -x

# grep xntpd /etc/rc.tcpip
start /usr/sbin/xntpd "$src_running" -a "-x"

To start the service issue,

# /usr/bin/startsrc -s xntpd -a "-x"
