To resolve this issue, change the default logging location.
To change the default log location:
- Browse to the datastore where you want to save the logs.
- Create a new folder, such as systemlogs.
- Click the Configuration tab of the host.
- Under Software, click Advanced Settings > Syslog.
- Set Syslog.global.logDir to [LUN_name]/systemlogs.
Notes:
- The default logging location is [] /scratch/log.
- You need not reboot the host for the changes to take effect.
Alternatively, you can also configure a syslog server. For more information, see Configuring syslog on ESXi 5.x (2003322).
