AsterNOS Uninstallation and Upgrade
9 min
Uninstall AsterNOS
We support uninstalling software that are not currently in use in AsterNOS, and we also support uninstalling all AsterNOS systems via ONIE to erase the disk of the entire partition where AsterNOS is located.
Uninstall Non-Current AsterNOS
- Run show image command to view the current AsterNOS system. Example:
sonic# show image
Current: AsterNOS_V3.1_R0406P01
Next: AsterNOS_V3.1_R0406P01
Available:
AsterNOS_V3.1_R0406P01
SONiC-OS-CX-NB-2.5- Run sonic-installer remove <version_name> command to uninstall older version. Example:
sonic# system bash
admin@sonic:~$ sudo sonic-installer remove SONiC-OS-CX-NB-2.5Remove All AsterNOS Systems
- Log in to the switch through the serial port and then run reboot command. Wait for a while until the system selection window appears. Please select ONIE within 10 seconds or it will default to enter AsterNOS.
- Later you will enter ONIE GRUB Menu and select ONIE: Uninstall OS. This will take a while to erase all AsterNOS systems and format the partitions.
- Wait for some time until the removal is complete, the system will automatically reboot and enter ONIE: Install OS.
