SP2000 Complete System Restore Configuration

In this section:

Replacing the MicroSD on an AMC121

When you replace the MicroSD card on any of the AMC121 cards, you must restore the system backup using a USB key.

Before you start the restore process, you must have

performed a complete system backup (software image and system data) using a USB key before changing the MicroSD
installed a new MicroSD on the AMC121, as required

Restore a Complete System Backup from a USB Key on a Single AMC121

It is assumed that before you start the restore process you have done the following:

performed a complete system backup (software image and system data) using a USB key
installed a new MicroSD on the AMC121 if required
powered up the SP2000
are familiar with the system Ethernet configuration
are connected to the SP2000 as required
are logged onto the SP2000 as the root user

If you require help with the above tasks, refer to the Hardware Installation and Initial Configuration Guides (contact Customer Support).

Install the Software Load on the AMC121 CPU using a USB Key

Start

Insert the USB key into the USB port on the AMC121 CPU.
Reset the AMC121 CPU to begin rebooting from the USB key.
- For 3U, refer to To deactivate the new AMC121 CPU for the proper deactivation procedure. When the blue LED stops blinking and remains illuminated, continue to the next step.
- For 13U, use the VSE CLI interface to deactivate the AMC121 CPU, if the AMC121 CPU is not deactivated yet.
```
hardware app-blade deactivate <frame shelf slot subslot>
```
Activate the AMC121 CPU.
- For 3U, activate the CPU by pressing the card's ejector handle toward the front panel. When the AMC121 is operational, the blue hot-swap LED turns OFF.
- For 13U, use the VSE CLI interface and enter the following command:
```
hardware app-blade activate <frame> <shelf> <slot> <subslot>
```
Press F2 while the AMC121 CPU is powering up to enter the BIOS.
If the AMC121 CPU starts to lilo boot, you have missed the chance to press F2.
- For 3U, reset this card by pressing the Reset button on the AMC121 CPU faceplate and try again.
  
  Tip
  
  If using the ejector handle to reset the CPU, refer to To deactivate the new AMC121 CPU for the proper deactivation procedure.
  
  When the blue LED stops blinking and remains illuminated, press the card's ejector handle toward the front panel again to re-activate the card.
- For 13U, deactivate the card again and then re-activate the card using the VSE CLI interface.
Navigate to the Main window and make sure that the System Time and the System Date are set to the local time and date on the working CPU and the other CPU in the operation regardless of timezone.

Caution

You must set the System Time and the System Date to the local time and date on the working CPU and the other CPU in operation regardless of timezone in this step even if you have done this task before. Otherwise, the system will not function as expected.

For example, if the local time on the working CPU is 07:30:25 EST, the time entered in the BIOS on the restored AMC121 CPU and the other working CPU has to be 07:30:25 even though the timezone is not entered.
Navigate to the Exit window, select Load Custom/Optimal Defaults, and press ENTER.
Select OK, and press ENTER.
Navigate to the Boot window and select Hard Disk Drives.
Select the 1st Drive, highlight the device that corresponds to the USB key and press ENTER.
Select 2nd Drive, highlight the device that corresponds to the AMC121 CPU's SD card, and press ENTER.

Tip

The second boot drive should be the AMC121 CPU's SD card (USB: Single Flash Reader) and the third boot drive should be the AMC121 CPU's hard drive, which should be in the format SATA: <hd manufacturer/model>. In the following example, the hard drive entry is SATA:PM-FUJITSU MH.
Navigate to the Exit window, select Save Changes and Exit, press ENTER.

Enter root, and press ENTER.

Installation Details
================================================================================
Card Type: AMC121
Target Shared Storage Device:
Node: /dev/sda
Transport: ata
Description: ATA Hitachi HTE54322
Installer Key Device:
Node: /dev/sdb
Transport: usb
Description: Generic Flash Disk
Target Root File System Device:
Node: /dev/sdc
Transport: usb
Description: Single Flash Reader
Do you wish to repartition/reformat the logs/stats device /dev/sda (y/n)?

Enter y and then press ENTER.

The system will be installed on device sdc.
Confirm (y/n)?

When prompted, remove the USB key and press ENTER to reboot the AMC121 CPU.

Please remove the USB key. Upon reboot into the OS installed on the permanent
drive there will be additional automated installation steps and a second reboot.
When this reboot has completed:
- for new install the login banner will indicate when system initialization
steps are required.
- for restore the data will be applied to the system and applications will
start.
Manual installation sanity checks can be performed at that time.
Please remove the USB key and press ENTER to continue (reboot).
<PRESS ENTER>

If the AMC121 CPU does not boot without the USB key, go to the BIOS settings and make sure that the SD card is set as the first boot device.
1. The screen output for Boot > Hard Disk Drive should appear as follows.
2. The screen output for Boot >Boot Device Priority should appear as follows.
After the system reboots and the following prompts appear, go to the next step.
```
(none) login:
Password:
```
Enter root for login and the same password for the working CPU, and then press ENTER.

If the root password from the working CPU is not working, try to use password changeme instead.
Verify the OS version by running following command at the Linux prompt on the restored AMC121 CPU.
```
cat /etc/pt-release
```
Make sure that the Chassis Type is set to the appropriate chassis (for example, 3U) on the restored AMC121 CPU by doing the following:
1. To verify the Chassis Type, enter the following:
```
# /usr/sbin/getChassisType
```
  Tip
  
  On a 13U 16-slot system, this command returns 13U. On a 13U 14-slot system, this command returns 14SLOT.
2. If the Chassis Type is not set to the correct type, enter the following:
```
# /usr/sbin/setChassisType -c <chassis type>
Set Chassis Type to <chassis type>
```
  For example:
```
# /usr/sbin/setChassisType -c 3U
Set Chassis Type to 3U
```

From the restored AMC121 CPU, make sure that this CPU can ping its carrier card.

# ping -c 3 169.254.100.31

Restore a Complete System Backup from a USB Key on a Single AMC121

Start

Login to the CPU.
```
echo (slot number) > /opt/restore_identity
```
For example, if the CPU is supposed to be slot 24, type the following:
```
echo 24 > /opt/restore_identity
```
Enter the following, and press ENTER.
```
systemctl restart sonus-system
```
The CPU restores the data and then reboot itself.

Tip

The CPU restore can take up to 15 minutes.
