When you put in VMware ESXi to an SD card or USB stick (or when utilizing Boot from SAN), the yellow exclamation mark icon is displayed subsequent to the host title within the vCenter consumer console, and the next warning seems on the Summary tab:
System logs on host ny-esxi21.woshub.com are saved on non-persistent storage.
The esx.downside.syslog.nonpersistent warning implies that the system writes logs (scratch) to the non-persistent USB gadget and if you happen to restart your host, they received’t be saved. Thus, in case of any host points, you received’t be capable to look at its logs or present any knowledge to VMWare technical help workforce. To take away the warning, you will need to change the log storage path to an area disk or a VMFS datastore (or configure a syslog server) within the ESXi host settings.
This information refers back to the new HTML5 vSphere 6.7 consumer. In earlier vSphere variations it’s configured in the identical manner, nevertheless, the names of choices or sections could differ.
- Open the vSphere consumer and choose your ESXi host with the warning within the Hosts & Clusters;
- Go to the Configure tab and click on Advanced System Settings;
- In the checklist of superior settings, click on Edit and sort Syslog.world.logDir within the Filter discipline. As you may see,  /scratch/log folder is used to retailer the ESXi logs;
- Change the trail within the Syslog.world.logDir variable to [youtVMFSdatastorename] /systemlogs.
You should create /systemlogs folder on the VMFS datastore upfront. Otherwise, you’re going to get this error:
A normal system error occurred: Internal error.
- If the Syslog.world.logDir discipline is empty, examine the worth of the ScratchConfig.CurrentScratchLocation parameter. It reveals the trail to the scratch partition containing logs.
You also can change the log path utilizing the PowerCLI command immediate:
get-vmhost ny-esxi21 | Get-AdvancedSetting -Name "Syslog.world.logDir" | Set-AdvancedSetting -Value "[HQVMFSDatastore1] /system_log_folder_name"
You also can change the worth of Syslog.world.logDir utilizing the Host Profiles. You can apply this profile to all ESXi hosts in your datacenter.
