SP2000 Rollback to a Previous Software Version

In this section:

The rollback to a previous software version is performed using the following method. It is recommended that you do not run SS7 traffic during this process.

You must use the Menu-based user interface (Menu UI) to perform this procedure.

It is recommended that you review the software rollback terminology before starting the procedure in this section (refer to Software Rollback Terminology).

Note

The screen captures or code blocks on this page are examples only and are the same between releases with the exception of the software version numbers.

Caution

It is recommended that you use the Rollback option with caution. To minimize the risk of a full

Unable to show "metadata-from": No such page "_space_variables"

outage, one CPU is rolled back first and then the other.

Before you execute this action, consult with Customer Support to determine if the rollback is required. Customer Support can assess whether a manual intervention could complete the upgrade and, therefore, the rollback outage can be avoided.

Caution

Do not log onto the system using the shared IP addresses on the Management CPUs during the rollback process described in this section. These addresses are disabled as part of the rollback process.

Note

To rollback the IO back cards, use the same procedure required to upgrade the IO cards.

Rollback in-container!
Rollback targets: [24, 14]
Type "yes" to proceed (yes/no):

If any cards are unreachable (for example, an IO slot that may not have been configured yet), a warning message is displayed.
```
Warning: some machines could not be properly contacted.
Type "skip" to skip those CPUs [] or "yes" to proceed anyways. Anything else will abort the rollback process.:
```
Perform one of the following options
1. Enter skip to ignore the CPUs inside the square brackets [ ] and continue with the rollback. If none of the unreachable cards are CPUs, the list will be empty. It is recommended to skip those cards.
2. Enter yes to continue the rollback process as if all the CPUs are reachable.
  
  Tip
  
  Entering anything else besides skip or yes will exit you from the rollback procedure.
The rollback procedure displays which CPU(s) will be rolled back. In this example, only one CPU needs to be rolled back because the other CPU is already in the previous load.
```
Rollback in-container!
Rollback targets: [14]
Type "yes" to proceed (yes/no):
```
Enter yes to start the rollback procedure.
If there are multiple CPUs, the remote CPU will be rolled back first. After the remote CPU is finished, you will be prompted to start the rollback for the local CPU.
```
Ready for next rollback. Type "yes" to proceed
```
Enter yes to start the next rollback procedure.
Once all required rollbacks are completed, log onto the system and make sure that the rollbacks were successful (see To verify that the rollback has been properly installed).

Caution

If an asterisk appears beside any of the system cards during the verification process, the rollback for the respective card was unsuccessful. In this case, it is recommended that you contact Customer Support.

At the Linux prompt, enter startmenu, and press ENTER.
Select System and press ENTER.

Verify that the software has been rolled back properly by doing the following:

navigating to the Software Revisions screen.

Selecting the required card (in this procedure CPU Versions), and pressing ENTER.

Make sure that the SS7 software and Linux software has been rolled back, all cards are running the same software, and that there is no asterisk beside any of the cards.

Tip

The output of the “CPU Versions” command shows that the CPU card has “UPGRADED” status if this is the first time the command is issued after an upgrade. All subsequent “CPU Versions” commands show the number of processes running on each CPU
