Trying to upgrade Vcenter 6.5 to 6.7 , The following error comes up
Cannot validate target appliance configuration as not enough information from the source appliance can be collected. For more details check out the server logs
SSH into new 6.7u1 applicance:
“software-packages install –url –acceptEulas”
“shutdown reboot -r “patch reboot””
In order to ensure protection is not affected when upgrading or replacing a vCenter, the vCenter database should be preserved
Upgrade then make sure Replication all comes back green
Before Upgrading the Hosts to the latest ESXi , double check the current version of Zerto supports the version you are putting on or you will get the error on Upgrade “VRA unsupported esx version”
Once VM’s migrated , shutdown VRA and VRAH , restart upgrade host
You can migrated VCC machines to other hosts without effecting replication
Recently a customer had filled up their free SQL Express Database with Events and Tasks from Vmware. The Hosts has both gone to Disconnected with error
cannot synchronize host cannot contact the specified host
and when trying to re-add the error would be displayed
VIM_VCDB database ‘PRIMARY’ filegroup is full
failed because the resulting cumulative database size would exceed your licensed limit of 4096 MB per database.
SQL Express has a 4GB database limit, we need to clear out the old logs and don’t want to install and download SQL management studio so we need to run the below in command prompt with the same user that installed the DB or has write permissions to it!
The permanent solution would be to move the SQL server to a full version of SQL Server or to migrate to Vcenter Standalone server ( Hosted on Linux! )
Recently had a virtual machine show up with a disk size of 0MB in the Vmware client. The machine was still running however Veeam backups were failing.
Checking the snapshots on this machine showed there was none however opening the VM folder in the datastore showed there were loads of snapshot files.
Running a consolidate on the Vmware Snapshots , then helped list the Snapshots which could be removed by the client
Removing the VM from the Esxi Host and re-adding this should do the same thing
Also try removing the CDRom Mapping if it maps to an Inactive NFS share
Error: Unable to find SRA files. You must install SRA before adding or modifying an array manager.
1.Took RDP to both the SRM servers.

3. Performed Modify/install on both the SRM servers.
4. Reconfigured array pairing by typing the pureuser ID and password.
Unable to establish CIM session with ESX server: The remote server returned an error: (501) Not Implemented.

Need to update Vmware
The below command needs to be run on Each Host , it will remove the old one and install the new one
esxcli software vib install -d https://update.nimblestorage.com/esx6.5/ncm/index.xml
The host then needs to be rebooted to install
You can add https://update.nimblestorage.com/esx6.5/ncm/index.xml , as an update location via Update Manager in Vmware Vcenter Server and Add a Host Basline Extension , then remediate this to the hosts as well
