Heartbeat Port Configuration Check at vCenter and ESXi

ESXi sends an heartbeat to vCenter Server over UDP port 902 to signal that host is accessible over management network. This is default for heartbeat communication, although this can be changed at vCenter and ESXi. When ESXi host intermittently disconnects from vCenter, then one of possible cause is port misconfiguration either at ESXi or vCenter. So in this post i am going to share how can you check, heartbeat port configuration?

Check Heartbeat Port Configuration at vCenter Server
In Appliance based vCenter you can check this, not only from vSphere Web Client. This can be checked from vpxd.cfg file and the location of this file is /etc/vmware-vpx/vpxd.cfg, by connecting with vCenter Server Shell.

Check Heartbeat Port Configuration at ESXi Host
Open /etc/vmware/vpxa/vpxa.cfg file, and review the port configuration

So this is how you can port configuration details at both ESXi and vCenter.

vCSA 6.5 a.k.a vCenter Server Appliance 6.5 Backup Step by Step

As we know, vSphere 6.5 bundled with couple of new features. One of the "OUT-OF-BOX" feature is file level backup of vCenter Server Appliance. This backup can be done without using any third party tool. This feature is exclusively available only in vCenter Appliance not in Windows based vCenter.

Procedure to Take vCSA 6.5 backup
1. Connect with VAMI of vCSA
VAMI = Virtual Appliance Management Interface
Open web browser (Google Chrome Preferred) > https://vcsafqdnorIP:5480 > Username = root, Password = As Configured > Login

2. Click on the Backup Button

3.  Select the Protocol, Location, Port Number, Username, Password > Click on Next
Protocols Supported = HTTP, HTTPS, FTP, FTPS, SCP
Optionally You can Encrypt the data with AES 256 Encryption by providing password. Password used for encryption is not stored anywhere, so if lost no way to recover those backup files.

4. You can select parts to backup as listed below > Click on Next

5. Click on Finish

6. Review the Backup Progress

7. Click on OK once it is completed

Note : If you are trying to take the backup again to the same location, you will get the error message "Location xxxxxxxxxxxxx is not Empty". Select new location to take the vcsa backup again

vSphere VM Connected to Unknown Network - Issue Resolved

A vSphere Administrator reports that its VM is connected with Unknown Network but cannot figure it out "How this VM is connected with Unknown or Extra Network". Let's discuss this situation when this can happen. As we know, whenever the snapshot is created many states of a VM gets captured. One of state is VM settings state. Settings State means all configuration settings of that VM gets captured. Lets take the example:- I have VM configured with two NICs (one connected to one portgroup and another one connected to another portgroup) gets captured in the snapshot. After taking the snapshot if you have deleted one of NIC, under the networks tab of the VM it will still show you two portgroups name. That's were the problem starts for the vSphere Admins. Now to get rid from this network you have to delete the snapshot. I am going to demonstrate the same scenario here:

1. I have VM with two NICs, connected with different portgroups

2. I took the snapshot of this VM

3. Then i have deleted one of the NIC

4. In my VM networks tab, there are still two portgroups. However my VM has one NIC only now

5. Now to get rid from this extra network i have deleted my VM snapshot

6. Now check the VM networks tab and only portgroup is listed

Demo Completed!!!!!
