Description

1

Before the update, read this document carefully to ensure that you have learned all the content. For any problems or suggestions pertaining to the document, contact technical support.

2

To reduce impacts on services, switch services to other nodes or perform the upgrade during off-peak hours.

3

After the upgrade, ensure that the versions of the driver and firmware are consistent.

4

Before the upgrade, ensure that the OS is running properly and the firmware and dependent drivers are properly loaded. Otherwise, reset the system before performing the upgrade. For details, see How Do I Check Whether the Device Is Running Properly?

5

Do not modify the /etc/ascend_install.info file unless necessary. Otherwise, system functions will be unavailable.

For an upgrade from an earlier version to NPU C72B050 or later, skip system reboot in Upgrading the Ascend NPU Firmware and system reboot in Upgrading the Ascend NPU Driver. After the driver upgrade is complete, perform a restart.

You can run the following command to check the NPU version:

/usr/local/Ascend/driver/tools/upgrade-tool --device_index -1 --component -1 --version

Version Requirements

You are advised to use the driver and firmware in the same software matching list for Atlas 800 (model 9000) training server so that the driver matches the firmware.
