Resolving Server Reboot Failure: NIC Driver Update Issue

B.

When a new driver is applied to a network interface card (NIC), it can sometimes cause issues that prevent the server from booting up properly. In such a scenario, the best way to resolve the problem would be to try the following troubleshooting steps:

Option A: Boot using recovery console and restore the previous driver If the new driver is causing the issue, reverting back to the previous driver can help fix the problem. Booting using the recovery console allows the user to access the system files and restore the previous driver from the system backup. This option can be helpful if the issue is driver-related and there are no other underlying problems. However, this option may not always work if the system backup is not up-to-date or if the problem is not caused by the driver.

Option B: Boot the server, press F8, and access last known good configuration This option allows the server to boot using a configuration that worked properly the last time it was started. This can be helpful if the issue is caused by a recent change in the system configuration, such as a driver update. By accessing the last known good configuration, the server can bypass the changes made to the system and boot up successfully. However, this option may not work if the last known good configuration is not compatible with the new driver or if the issue is not related to the system configuration.

Option C: Restore the server using the last backup tape If the server cannot be restored using the recovery console or the last known good configuration, the next best option would be to restore the server using the last backup tape. This option can help fix the problem by restoring the system files and configuration to a previous state. However, this option may result in data loss if the backup tape is not up-to-date or if the issue is not related to the system files or configuration.

Option D: Boot the server with ASR option Automated System Recovery (ASR) is a feature that allows the server to automatically recover from a system failure. By booting the server with ASR option, the system can automatically diagnose and repair the problem. This option can be helpful if the issue is caused by a hardware failure or a system file corruption. However, this option may not work if the issue is caused by a software or configuration issue.

In summary, the BEST way to resolve the problem depends on the cause of the issue. If the issue is caused by a driver update, option A or B would be the best way to resolve the problem. If the issue is caused by a hardware failure or a system file corruption, option D would be the best way to resolve the problem. If none of these options work, restoring the server using the last backup tape (option C) may be necessary.
