vSphere 7 Cloud Infrastructure for Modern Applications Part 1:

vSphere 7 Cloud Infrastructure for Modern Applications Part 2

vSphere 7 with Kubernetes

Now and over the next 5 years we are seeing a shift in how applications are built and run. In 2019 Line of Business (LOB) IT, or shadow IT, spend exceeded Infrastructure and Operations IT spend for the first time*. Modern applications are distributed systems built across serverless functions or managed services, containers, and Virtual Machines (VMs), replacing typical monolithic VM application and database deployments. The VMware portfolio is expanding to meet the needs of customers building modern applications, with a portfolio of services from Pivotal, Wavefront, Cloud Health, bitnami, heptio, bitfusion, and more. In the container space VMware is strongly positioned to address modern application challenges for developers, business leaders, and infrastructure administrators.

Launched on March 10 2020, with expected April 2020 availability, vSphere 7 with…

Unable to extend Datastore Space

August 7, 2017 Leave a comment

Issue Definition:

This is one of the most frequent requirements a VMware Administrator faces in a day to operations where requests to extend the disk size of VMs are placed and unfortunately the Datastores are running out of Disk space.

I was involved in a similar activity and had to request the Storage Team to extend the LUN size. Post extension of LUN space by them, the extended space was visible in the capacity of Extent Device pane after rescan of disks. I then tried to extend the space of the Datastore. But for my surprise when I clicked on “Increase” button I was unable to find the LUN with extended space which usually appears.

I tried using Web Client keeping in mind ver. 5.5 onwards most of the functionalities are covered and managed in Web Access than VIClient Access. However I faced the same scenario there as well.

Solution:

Though the above issue can be resolved using “partedUtil”, “vmkfstools”, cmdlets the easiest solution is to connect any one of the hosts directly using VIClient and perform the same actions which you are trying to do it from vCenter Console. This way I was able to resolve my issue. Now its your turn. 🙂

PowerCli Command to get RDM details of a VM

January 3, 2017 Leave a comment

Its quite a known thing that every administrator has his/her own requirement of extracting the details from the vSphere Infra at any given point of time.

Similarly I was trying to get hold of a command to display the number of RDMs attached to a VM along with details such as WWN, Name, Size, Path etc. Got hold of a command from VMware KB 2001823. Only change in the below command I made is added the VM name after Get-VM | Get-HardDisk…..

Get-VM | Get-HardDisk -DiskType “RawPhysical”,”RawVirtual” | Select Parent,Name,DiskType,ScsiCanonicalName,DeviceName | fl

The same KB also mentioned how to bring this output to a text file.

Get-VM | Get-HardDisk -DiskType “RawPhysical”,”RawVirtual” | Select Parent,Name,DiskType,ScsiCanonicalName,DeviceName | fl | Out-File –FilePath RDM-list.txt

But this was missing Size and File Name for which I added “Filename”,”CapacityGB” in the select parameter and Voila!! I got the output.

Get-VM  | Get-HardDisk -DiskType “RawPhysical”,”RawVirtual” | Select Parent,Name,DiskType,ScsiCanonicalName,DeviceName,”Filename”,”CapacityGB” | fl | Out-File -FilePath D:\RDM-list.txt

Now there was a new desire to view the output in a tabular format and finally below command suited all my requirements:

Get-VM  | Get-HardDisk -DiskType “RawPhysical”,”RawVirtual” | Select Parent,Name,DiskType,ScsiCanonicalName,DeviceName,”Filename”,”CapacityGB” | Format-Table -AutoSize | fl | Out-File -FilePath D:\RDM-list.txt

Output for the command:

Ports for vCenter to ESXi communication

January 7, 2016 Leave a comment

After some brainstorming and multiple discussions with Network and Security folks, I could build this table which specifically mentions the required ports for the communication between vCenter 5.x and ESXi 5.x. All the TechNet articles just mention the ports required, however Network and Security team will not move forward until we provide details such as source and destination. Hope this table bridges that gap…

VMware KB: An ESXi 5.x host PSODs with a panic containing: be_function_internal_query_firmware_config be_function_object_create

VMware KB: An ESXi 5.x host PSODs with a panic containing: be_function_internal_query_firmware_config be_function_object_create.

An ESXi 5.x host PSODs with a panic containing: be_function_internal_query_firmware_config be_function_object_create (2120158)

 

Symptoms

An ESXi 5.x host PSODs with a panic screen similar to:

 

be_mcc_mailbox_wait@<None>#<None>+0x6c stack:

be_mcc_mailbox_notify_and_wait@<None>#<None>+0

_be_mpu_post_wrb_mailbox@<None>#<None>+0x5a st

be_function_internal_query_firmware_config@<No

be_function_object_create@<None>#<None>+0x222

fob_setup@<None>#<None>+0xa1 stack: 0x41000638

pf_reset@<None>#<None>+0x29c stack: 0xd704400,

vmklnx_workqueue_callout@com.vmware.driverAPI#

helpFunc@vmkernel#nover+0x52e stack: 0x0, 0x0,

 

Cause

This PSOD is caused by an outdated emulex driver running on the host.

Example: be2net driver version 4.1.255.11

 

Resolution

Update the be2net driver to the latest version.

The latest versions can be located here:

http://www.emulex.com/downloads/emulex/drivers/vmware/vsphere-51/drivers/

VMware KB: Unable to power on a virtual machine on an ESXi 5.0 host with the error: Unable to create a swap file. The value of ‘sched.swap.dir’ specified in the VM’s configuration file is invalid.

June 16, 2015 Leave a comment

Unable to power on a virtual machine on an ESXi 5.0 host with the error: Unable to create a swap file. The value of ‘sched.swap.dir’ specified in the VM’s configuration file is invalid. (2119464)

Symptoms

The virtual machines datastore was migrated prior to the issue.Migrating the virtual machine to the original datastore resolves the issue.Unable to power on virtual machine with error:

An unexpected error was received from the ESX host while powering on VM vm-xxxxx.

1. Failed to power on VM.

2. Unable to create a swap file. The value of ‘sched.swap.dir’ specified in the VM’s configuration file is invalid.

Cause

This issue is caused after the migration of a virtual machine to a new datastore when the sched.swap.dir path is not updated in the virtual machine’s .vmx file.

Resolution

To resolve this issue manually updated the sched.swap.dir to the new datastore:

1. Connect to the ESXi host with an SSH session using root credentials.  For more information,  see Using ESXi Shell in ESXi 5.x and 6.0 (2004746)Navigate to the virtual machines directory on the ESX host with this command:

cd /vmfs/volumes/datastore/virtual_machine

 

2. Open the .vmx file with a text editor:

vi virtual_machine.vmx

 

3. Find the sched.swap.dir entry and update it the path to match were the virtual machine is currently located.

For Example:

sched.swap.dir = /vmfs/volumes/datastore1/testvm/

 

4. Reload the virtual machine on the ESXi host.  For more information, see Reloading a vmx file without removing the virtual machine from inventory (1026043).

 

5. Power on the virtual machine.
