A couple of days ago Runecast Analyzer has been upgraded to version 3.0.0. With that upgrade a very important beta-feature became GA: HW Compatibility and Upgrade Simulator.
I used to run the Runecast service account with readonly privileges. It has been sufficient up to version 2.7.x. Even the hardware compatibility check (beta) did work with readonly privileges. After upgrading my appliance to version 3.0.0 (GA), I found a notification. Missing privileges..
Once you open host details and click on I/O devices tab, there’s further information.
During a cluster routine check with RVtools I’ve seen a warning.
Warnings like this on a vCenter appliance let my alarm bells ring. Partitions filling up close to 100% are not a desirable condition. But let’s have a look into VAMI (vCenter Appliance Management Interface).
Now that’s strange. Everything seems to be in a green state. It’s a VCSA 6.7 Update 2a (22.214.171.124000). Older versions did show a storage warning. “File system /storage/archive is low on storage space“. But this appliance seems to be happy. Let’s have a look at the shell, to see what’s really happening.
It looks like mount point /storage/archive is almost filled up.
To manage a vCenter Server Appliance (VCSA) there’s a special user interface called Virtual Appliance Management Infrastructure (VAMI). You can access it by entering the FQDN of your vCenter into a browser, followed by port 5480.
This UI helps you to monitor your vCenter Virtual Appliance. You can change basic settings, apply updates and watch system status.
After updating a VCSA to the latest version of vCenter, I had to reboot the appliance. After the reboot process had finished, I wasn’t able to login to VAMI. Sometimes services need quite some time to become available, but even waiting for a longer period of time (a cup of coffee) nothing happened. VAMI presented a login screen, so obviously the webserver was up and running. But each time I entered the (correct) credentials I got the message “unable to login”. Screenshot is in German but you’ll most likely get the point ;-).
I’m a great fan of vSphere-Client a.k.a HTML5 client. The user interface based on project clarity is an eye catcher and the user experience is great. But sometimes you’re forced to use the old Flash based flex-client. Not with latest vCenter Server 6.7 but with older releases like vSphere 6.0.
We were facing compatibility issues between flex-client 6.0 and NSX 6.4.4 although it’s a supported combination.
