Chapter 5 Migrating to Solaris 10 and Cisco PGW 2200 Softswitch Software Release 9.8
Upgrading Lively from Sparc-based Platforms to Opteron-based Platforms
Note No provisioning is allowed during the live upgrade. Before performing the live upgrade, you must stop
all the MML provisioning sessions and quit from the MML interface on the old Sparc-based active and
standby pair of Cisco PGW 2200 Softswitches. Provisioning is allowed only when the new pair of
Cisco PGW 2200 Softswitches on Opteron-based platforms are running normally as an active and
standby pair. To view the status of the Cisco PGW 2200 Softswitch, use the MML command “rtrv-ne”.
Live Upgrade Procedure
This section describes the live upgrade procedure from Sparc-based platforms to Opteron-based
platforms.
First, you migrate PGW 2 to PGW 4. When the migration is complete, PGW 4 can serve as a replacement
of PGW 2. You stop PGW 2 and do a switchover from PGW 1 to PGW 4. When the switchover is
complete, you migrate PGW 1 to PGW 3. Finally you enable the MMDB database replication between
PGW 3 and PGW 4.
Perform the following steps to do the live upgrade:
Step 1 Verify that the pom.dataSync variable is set to False on both PGW 1 and PGW 2. To view or modify the
pom.dataSync variable, use an editor such as vi to edit /opt/CiscoMGC/etc/XECfgParm.dat.
Note You must set pom.dataSync to false on the active and standby pair of
Cisco PGW 2200 Softswitches before you perform the live upgrade.
Note If you modify the pom.dataSync variable, make sure you save the file,
/opt/CiscoMGC/etc/XECfgParm.dat. You don’t have to restart the Cisco PGW 2200 Softswitch
after the modification of this variable.
Step 2 On PGW 2, log in as root. Then run the following script under /opt/CiscoMGC/local.
# cd /opt/CiscoMGC/local
# ./liveUpgrade.sh export
Text similar to the following is displayed:
You are running as root - Good...
Stopping TimesTen database replication on sh-hox
Stopped TimesTen database replication successfully
Backing up the Main Memory Database (MMDB) on sh-hox
Back up the Main Memory Database (MMDB) successfully
All configuration files were exported successfully in /var/tmp/upgrade/
please ftp them to your file server
Step 3 Back up the odbc.ini file using the following command:
# cp /opt/CiscoMGC/local/.odbc.ini /var/tmp/upgrade/
Note Step 3 is only required when PGW 2’s software version is Cisco PGW 2200 Softswitch
Release 9.7.
