One of my favorite new features of vSphere 6.5 is definately vCenter HA. I was checking out alerts when I noticed i had an alarm for vCenter HA being degraded.
Looking through the GUI, I was unable to find anything in regards to why the Health was a warning and why the components would not sync. Then I remembered a previous case I had opened for VCHA.
There is a log file located in /var/log/vmware/vcha
As soon as i opened up vcha.log the issue was plain and clear.

My Password has expired! How is this possible? Lucky for me Féidhlim O’Leary has already encountered this issue, and opened up a support case. The problem is due to the vcha user password expiring, it’s quite a simple fix.
If you check the password age, you can see when the last password change is. This example my password has not expired yet, you can check the expiration date but running chage –list vcha
[email protected] [ ~ ]# chage --list vcha Last password change : Jan 05, 2017 Password expires : Mar 06, 2017 Password inactive : never Account expires : never Minimum number of days between password change : 1 Maximum number of days between password change : 60 Number of days of warning before password expires : 7
If the password is already expired, you can reset it by typing
Note: You will need to do this on all 3 nodes. You can ssh to the peer and witness through the primary if you know those IP’s
Now, we can set our password to not expire.
[email protected] [ ~ ]# chage -m 0 -M 99999 vcha
If we recheck the password expiration, we can now see it is set to not expire.
[email protected] [ ~ ]# chage --list vcha Last password change : Jan 05, 2017 Password expires : never Password inactive : never Account expires : never Minimum number of days between password change : 0 Maximum number of days between password change : 99999 Number of days of warning before password expires : 7
We will need to wait a few minutes for our replication cycles to complete, and voila! VCHA is now Healthy!
