Last week, VMware released a knowledge base article KB 95536, which includes a script for fixing the LCM service on SDDC Manager. Due to an invalid index file that was recently pushed to the VMware depot, the LCM service on SDDC Manager has downloaded several incorrect upgrade bundles. This is the reason why the LCM […]
While applying the async vCenter 7.0U3o patch to workload domain (related to VMSA-2023-0023) in VCF on VxRail 4.x, I faced an issue with VxRail prechecks in SDDC Manager: ‘VxManager HTTP Request failed with invalid status code’ If you open the Physical View of VxRail cluster in vCenter, page keeps loading or it shows ‘Unable to […]

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.

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 […]
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] […]
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 […]
