1 Preface
Due to global time differences, it is a must to change the time zone and time to the local time zone and time. During the modification, the service is interrupted because the cluster is stopped. Thus, the time zone must be modified during the night when the traffic is low.
2 Time Modification of the HLR 9820
This chapter introduces the following contents:
Modification Method for the Sun Platform Modification Method for the IBM Platform
2.1 Modification Method for the Sun Platform
I. Modifying HDU Dual-System Time
Caution:
Before modification, ensure that the dual-system is set to the non-CLUSTER state and the TC or SC card is available. You must modify the time zone on both hosts.
1) Checking the Solaris 8 Time Zone and Time
Check the Solaris 8 time zone and time. If they are inconsistent with the actual situation, change them immediately.
To check the Solaris 8 time zone, do as follows:
Execute the following command:
root@hwhlr-phx#echo $TZ
Compare the output result with local time zone.If the output result does not match the local time zone, change the

TZ value in the file TIMEZONE under the directory /etc to the standard value.

System Time Modification (for 3G) For Internal Use
Caution:
The concept of time zone is different between the Solaris 8 operating system and the Windows operating system. You must observe the following rules to set the time zone: If the time zone displayed under the Windows operating system is
GMT+3, the time zone displayed under the Solaris 8 operating system must be set to GMT–3, and so on.
For the domestic operating system, the Solaris 8 time zone must be set to GMT–8.
Otherwise, the clock synchronization system does not function well, resulting in the unpunctuality of the system clock.
To check the Solaris 8 local time, do as follows:
Execute the following command:
root@hwhlr-phx#date
Check that the local standard time matches the current output time.Otherwise, change the Solaris 8 local time.
2) Modifying Solaris 8 Time Zone and Time
If the Solaris 8 time zone is inconsistent with the local time zone, modify the time zone and then the time.
If the Solaris 8 time zone is consistent with the local time zone but the Solaris 8 time is inconsistent with the local time, only modify the Solaris 8 time.
Before modifying the Solaris time zone and time, you must close all the nodes in the Cluster at first.
To close all the nodes in the Cluster, execute the following command:
root@hwhlr-phx#scshutdown –y –g 0
To set the dual-system to the non-Cluster state, execute the following command:
ok boot –x
3) Switching the Solaris System Based on the Netro 240 Platform into the OK State

System Time Modification (for 3G) For Internal Use
To switch the Solaris system based on the Netro 240 platform into the OK state, do as follows:
Use the SC to connect the minicomputer.#telnet <sc_ip> (129.9.101.195/129.9.101.196)

sc>
Type #. to enter the sc> prompt mode. Execute the following command:
sc>break
Are you sure you want to send a break to the system
[y/n]? y
The host system is switched into the OpenBoot state.
4) Switching the Solaris System Based on the Netro 20 Platform into the OK State Log in to the minicomputer through the TC.
# telnet 129.9.101.197 5002/5003
Enter the command halt as user root.
The Solaris system is switched into the OK state.
Note:
You must ensure that the TC (for Netro 20) and SC (for Netro 240) are configured correctly. Refer to the HDU software installation guide for the TC and SC configurations.
5) Example
To modify the time zone of the dual-system, execute the following command:
root@hwhlr-phx#vi /etc/TIMEZONE
2006-07-04 All Rights Reserved Page 8 of 12
System Time Modification (for 3G) For Internal Use
Change the value of TZ to the right time zone, and then execute the following command to save the result and exit:
:wq
To change the time of host 1, do as follows:
Ensure that the system time zone is synchronized with the current environment.
On host 1, execute the following command:root@hwhlr-ph1# . /etc/TIMEZONE
Modify the time of host 1.root@hwhlr-ph1#date mmddHHMM[[cc]yy][.SS]
mmddHHMM[[cc]yy][.SS] indicates the standard time, where:
– mm: month
– dd: day
– HH: hour
– MM: minute
– cc: century
– yy: year
– SS: second
For example, execute the following command to change the system time to Fri 2004-03-26 14:53:43.
#date 0326145304.43
Fri Mar 26 14:53:43 GMT 2004
Execute the following command to synchronize the time of host 2 with that of host 1:
root@hwhlr-ph2#rdate hwhlr-ph1
Then restart both hosts.
Note:
The dual hosts must be started simultaneously.
root@hwhlr-phx#sync;sync;reboot

II. Synchronizing BAM Time with HDU Time
To synchronize the BAM time with the HDU time, do as follows:
6) After the HDU time modification is complete, right-click the icon of the time synchronization tool at the bottom right of the BAM desktop.
7) Click the time synchronization button.
The BAM automatically synchronizes the HDU time.
8) After the time synchronization, restart the BAMSERVER process.9) After the restart is complete, query the switch time through the
command DSP EXTM at the LMT.
If the switch time is incorrect, execute the following command to change it:
SET TIME:;

Use DAYLIGHT SAVINGS TIME?
11) Select No.12) Select the time zone based on the actual situation.
Note:
If the difference between the set time and the dual-system time exceeds 35 seconds, the system starts a service process. This phenomenon is normal.

IV. Restarting Both Hosts
16) Checking the Auto-Start Setting of the Cluster
Note:
Check the auto-start setting of the cluster on both hosts simultaneously.

Check that the file /etc/inittab contains the following contents:hacmp6000:2:wait:/usr/es/sbin/cluster/etc/rc.cluster -boot -
i # Bring up Cluster
If the above contents do not exist, execute the following command:# /usr/es/sbin/cluster/etc/rc.cluster -boot -Ri
17) Restarting Both hosts
To restart both hosts, do as follows:
Execute the following command as user root.
Caution:
You must start host 1 first and then start host 2.
# shutdown -Fr
Check if the time zone and time are correctly changed.# date
