VMware: System logs on host [hostname] are stored on non-persistent storage

April 7th, 2014 1 comment

Last week I installed some new vSphere hosts with flash disk storage. Some hosts has a yellow caution icon and a message stating:

Configuration Issues – System logs on host [hostname] are stored on non-persistent storage.




Verify the location of System logs:

  1. In vSphere Client, select the host in the inventory panel.
  2. Click the Configuration tab, then click Advanced Settings under Software.
  3. Ensure that Syslog.global.logDir points to a persistent location.

    The directory should be specified as [datastorename] path_to_file where the path is relative to the datastore. For example, [datastore1] /systemlogs.

  4. If the Syslog.global.logDir field is empty or explicitly points to a scratch partition, make sure that the field ScratchConfig.CurrentScratchLocation shows a location on persistent storage.




After a few minutes the logs are stored at the new location (in this case I used central storage):

VMware: VMware Data Protection (VDP) 5.5 IP/DNS could not be resolved

March 18th, 2014 No comments

During the network configuration at the VMware Data Protection (VDP) appliance I received this warning message:

IP/DNS could not be resolved. Please check the hostname, domain, and DNS values for forward and reverse lookup validation





VMware VDP whitepaper: Before you deploy vSphere Data Protection, an entry needs to be added to the DNS Server for the appliance IP address and FQDN. This DNS Server must support forward and reverse lookup. Failure to have DNS set up properly can cause many runtime or configuration issues.

As you can see, the nslookup failed:



Add the domain and search domain in the /etc/resolv.conf file


And make sure you’ve created a correct PTR record at the DNS server for reverse DNS functionality, at the DNS server:


Select: Create associated pointer (PTR) record
