Chapter 1: General Error-handling Procedure Chapter 1: General Error-handling Procedure This chapter explains how to analyze and troubleshoot general issues when they occur on your high-availability cluster. 1.1 Troubleshoot issues remotely 1. Sign in to DSM with the cluster IP address. Go to Synology High Availability and check the cluster status. If the status is Warning or Critical, follow the instructions in Chapter 2: SHA Troubleshooting according to the error message. 2. If you cannot sign in to DSM using the cluster IP, try the following: a. Use a computer located within the same network as your cluster and go to find. synology.com or open Synology Assistant. b. Find the cluster via the cluster name (under Server Name), or the cluster IP address. Note that the passive server IP address cannot be found here because it does not provide any services. Refer to this article for more information on how to find your cluster via find. synology.com or Synology Assistant. c. Try to sign in to DSM again. If the issue is still not resolved, continue to the section 1.2 to troubleshoot issues on-site. 1.2 Troubleshoot issues on-site If you are still unable to connect to your cluster through the 2 methods listed in the Troubleshoot issues remotely section, you need to go to the physical location of your Synology NAS devices for the next steps. • If the devices are powered on and the Power LED indicator is on, try the methods in the Troubleshoot issues remotely section again. • If the devices cannot be powered on or the Power LED indicators are blinking, refer to this article to resolve the power issue. Then, try to connect to your cluster again. • If you still cannot connect to the cluster through the methods above, refer to Chapter 3: Contact Synology Service to contact Synology Technical Support for further assistance. 01
