Let’s quick remind ourselves I/O flow and how do checksum calculation and disk encryption work in conjunction with deduplication and compression on vSAN All-Flash cluster while creating/modifying new vmdk. 1. Checksum – functionality to avoid data integrity issues – is calculated before writing data (the block) to the caching tier. vSAN created 5-byte checksum for […]
vSAN architecture includes critical services and mechanisms and it’s good to know and understand the key components that operates in the background. vSAN versions have changed over the years and there are newer and newer features but the architecture and core components are the same. So what happens at the lower level when we create […]
Some time ago I described the installation process of VMware Identity Manager 3.3.0 with vRealize Lifecycle Manager 2.1 using Ansible (link here). That time the only possible option to install vIDM with vRSLCM was a single node with internal PostgresSQL database. vRSLCM 2.x does not perform cluster-based installations of VMware Identity Manager. Fortunately it has […]
Two weeks ago VCF 4.3.1 has been released and few hours later I had an opportunity to test upgrade procedure. In this post I will show you how to upgrade VCF software, NSX-T, vCenter, ESXi hosts and vRealize Suite components if you have vRealize Suite deployed in your environment. It’s a pretty straight forward process. […]
Connect to psql ( ssh to vRLSCM ): 2. Select password vmid you want to replace to find password alias of that vmid: 3. Update vmid of password aliad with vmid you want to replace with:
When you add new vSphere cluster to the management or VI workload domain and provide expired or invalid vSAN license key, the subtask ‘Apply vSAN License in vCenter Server’ will fail: In /var/log/vmware/vcf/domainmanager/domainmanager.log you can find more details: 2021-04-21T11:53:22.184+0000 WARN [vcf_dm,9f492adb1719ed65,0ae2] [c.v.e.s.c.c.v.vsphere.VcManagerBase,dm-exec-8] VSAN license verification failed – assuming vSAN license not applied 2021-04-21T11:53:22.184+0000 DEBUG [vcf_dm,9f492adb1719ed65,0ae2] […]
To configure a file-based backup schedule for the SDDC Manager VM you must use the Cloud Foundation API because it’s not possible to configure it via GUI. BUT, before you can use the VMware Cloud Foundation API to configure a backup schedule, you must enable the feature creating properties file (feature.properties) in the /home/vcf directory […]
In the previous post I showed how to automate initial VxRail cluster configuration and deployment with Ansible. In this post, which is the next of a number of posts on VCF 4 on VxRail I will show you how to externalize embedded vCenter. As you know, by default, VMware vCenter server is internal to the […]
As we all know, lazy sysadmin is the best sysadmin so even few clicks may cause you feel exhausted. That’s why I wrote Ansible role to automate VCF Cloud Builder deployment using ‘vmware_deploy_ovf’ module. Of course some OVA property keys were needed, but they can be found under ProductSection in OVF descriptor. This ansible role is for […]
Few posts ago i described how to automate certificates management for all VCF components using Ansible. In VCF versions prior to VCF 3.8, SDDC Manager allows the user to manage certificates of the VMware Cloud Foundation components except VxRail Manager. This post is just a quick update of vars for my ansible role. Just add […]
