Panic --> Backtrace: --> [backtrace begin] product: VMware ESX, version: 6.5.0, build: build-6765664, tag: hostd, cpu: x86, os: esx, buildType: release ---> Fix : NOTE : Put the host in Maintenance mode.  To be on a safe side, Copy the /productLocker/vmtools/ folder and its contents from a working host running the same ESXi version/build and replace them on the affected host. 1. take SSH on one working host and the affected host, let us take esxi0A is working and esxi0B is affected. 2. Login as "root" user 3. scp the /productLocker/vmtools/   folder and contents from the "good" host to the "problem" host $ [esxi0A:~]$ scp -rf /productLocker/vmtools/ esxi0B:/productLocker/ COAUTION: This will overwrite the vmtools  folder on the problem host, hence you could back...

Long boot time for ESXi hosts even after marking RDM LUNs as perennially-reserved    Error : 2019-09-17T19:47:44.846Z cpu39:65984)WARNING: celerity16fc: Task management abort failed, status:fffffffd 2019-09-17T19:47:44.849Z cpu21:66065)ScsiDeviceIO: 7916: Could not detect setting of QErr for device naa.600507680c8080dca80000000000058a.

Failed to load the sqljdbc_auth.dll cause : no sqljdbc_auth in java.library.path   The reason behind the issue:  The vcdb.properties file does not get automatically updated, when we change from Windows Authentication to SQL authentication. Since migration assistant uses that vcdb.properties file to obtain the database configuration, it fails to connect because it is expecting integrated authentication instead of SQL authentication.    Resolution:   To resolve this issue modify vcdb.properties file. This file can be located in Windows vCenter Server at C:\ProgramData\VMware\vCenterServer\cfg\vmware-vpx\vcdb.properties  and in VCSA at   /etc/vmware-vpx/vcdb.properties .  Now modify the vcdb.properties files as mentioned below from: driver = com.microsoft.sqlserver.jdbc.SQLServerDriver dbtype = mssql url = jdbc:sqlserver://;serverName= Server_Name ;DatabaseName= Database_Name ;instanceName= Instance_Name ;inte...

There is a default timeout value, which is 100 seconds, for the customization deployment process. we can configure a larger timeout value in tools.conf to extend the timeout limit of the process. Please notice that this timeout value is the up limit of time cost of the customization deployment process, the actual time cost of that will not be impacted by this value if it does not reach this up limit. Save and exit :)

Sanjay poonan has declared that using containers in digital transformation is a   “birthright” of VMware. wait wait.! what are these Buzz words? Why are they overused? Because they sound cool? or exciting?  Lets break this down and understand this in detail. Containers :   It’s a method to bundle packages of application and can be isolated with its Network, file system and its processes.   One of the famous container technology is “Docker” Kubernetes : When I have huge number of containers I need someone to manage and orchestrate it, that is achieved thru a technology called “Kubernetes” -> Google’s product which was made opensource.
