Ha Backout Procedure - Oracle Netra Server X5-2 Installation Manual

HA Backout Procedure

If you reach the point in your upgrade procedure where you have upgraded both
Oracle Communications Session Border Controllers in the HA pair to a later release
that you decide you no longer want to use, you can fall back to a previous release.
This section shows you how to fall back to an older image with both systems in your
HA node upgraded.
Note:
In the procedure below, ORACLE-2 is the active system and ORACLE-1 is
the standby system. The procedure uses these designations because the
prior procedure results in ORACLE-2 as the active system. The standby
system should be rebooted first.
To backout to a previous (older) release with the both OCSBCs in the HA node
upgraded:
Change the boot parameters on ORACLE-1 to use the appropriate Release S-
1.
CZ7.2.0 software image.
Using one of these methods, access the boot parameters on ORACLE-1:
•
•
Note:
If you need to revert to the older image, use the HA Backout Procedure.
Reboot ORACLE-1 using any of the ACLI reboot commands. Stop the booting
process by hitting the Space bar on your keyboard to halt boot-up when you
see this message: Press any key to stop auto-boot.... Type a c and press
Enter to begin displaying the boot parameters.
In the ACLI configure terminal menu, type bootparam and press Enter to
being displaying the list of boot parameters.
Scroll through the boot parameters by pressing Enter. Stop when you reach
the file name boot parameter.
The following example uses the filenames /boot/nnSCZ730.64.bz and /
boot/nnSCZ720.64.bz.
ORACLE-1# configure terminal
OCSBC1(configure)# bootparam
'.' = clear field; '-' = go to previous field;
boot device : eth0
processor number : 0
host name : boothost
file name : /boot/nnSCZ730.64.bz /boot/nnSCZ720.64.bz
In the example above, type the appropriate Release S-CZ7.2.0 file name next
to the Release S-CZ7.3.0 file name. Press <Enter> to continue scrolling
through the boot parameters.
