yes extend the disk when VM Power On.as per your Question .

[@Abhishek-qg9fj]

Thanks for the video sir

[@agileops]

Thanks Abhishek.

[@PremKumar-dg5gk]

It was easy to understand , How do we get a free testing lab for VM any suggestion?

[@yogaraj4242]

Can we extend drive without shutting down VM

[@agileops]

Hi Yoga, thanks for the comment, Yes this depends on guest os and if you are using dynamic disk too. In short os 2008 and above support online disk extension.

@@agileops I'm trying to extend vm storage on server 2016 and it has only C drive

[@supravabandyopadhyay5500]

i have two questions - 1. when we are increasing the RAM and hard drive ( C:) on IM-VM1, it is actually getting allocated from the free RAM and HD available in vcenter server , is it ? 2. if my above question is the case then from where are you actually adding the external hard disk ( D: in this case ) ?

[@agileops]

Thanks for the questions vCenter is just the management tool we use to manage the ESX host and VM. The virtual machine IM-VM1 is running on the ESX host my dell optiplex desktop running baremetal hypervisor ESX6.7 so the memory is allocated from the ESX host and Extra disk is allocated from the shared storage if you use it or local disk on the esx host in my senario.

I'm trying to increase my vm drive C from data store

[@yogaraj4242]

Take it to forward my case is have to extend drive space on VM data store without bringing server down is there any possibility to do the same?

[@annonymousghostdetector8425]

Can we assign more virtual cores than physical ?

[@agileops]

If the physical server has 16 cores you can give up to 16 however only to couple of VM if you give 16 cores to a lot you will see performance issue as cpu co-stop and ready time will become high. No we should not be assigning more cores the. What you have on the physical server as it will cause performance issues going forward. You may want to run low ratio vm like for an special application that needs more cpu, and run only one or two vms on the esx host. This will help you instead of having to install it on physical server we have the benefit of having it virtualised.

[@premkumarwaghmare4059]

If we extend memory and CPU on the fly, are there any chances the VM gets corrupt, When the VM is ON the Disk edit option is off but memory and CPU is on

[@agileops]

This is an optional feature that needs to be enabled if you test it in your yoir development environment And once happy enable it on production system. Disk option is disabled because you may have a snapshot running commit or delete the snapshot and you can add more disk.

[@maill2azhar]

Hi Sir, My question here is, "If we have extended the Memory, CPU from VMware Console but its not being shown in OS, in that scenario what can we do ..?"

[@agileops]

Depends on the OS you will need to reboot the server for 2008 to pick up a cpu increase. So the answer is increasing cpu is simple but you need to be mindful of the guest os and how it picks up the change in the cpu and Memory. Similarly os like 2008 does not support hot add cpu and hot plug Ram. So you will need to check if the guest os support it first. Regards Ibrahim

[@amoljunghare3610]

Hii Ibrahim very nice tutorial...When i am going to increase the disk size it is greyed out. I cant increase the disk space. Whats the actual problem??What I am doing wrong??

[@agileops]

Hi Amol, have you taken new Snapshot ? As snapshot locks 🔒 the disk. You will need to delete any snapshot or consolidate them then try again. Do let me know how you get on? Thanks Ibrahim

[@amoljunghare3610]

@@agileops Thnks for the info..When i will go to office i will recheck & let u know..

[@noufalh4820]

amol junghare pls make sure, hot plug option is enabled , by default this option is disabled .

[@agileops]

Did the issue get resolved? Was it snapshot running on the VM ?

[@agileops]

Noufal H yes by default hot add CPU and Hot plug memory is disabled.

[@junboo8730]

Can I increase the hertz(speed) of the CPU?, thank you.

[@agileops]

Hi, We can increase the cpu in count you can calculate it depending on the amount of cores you have added per socket.

[@junboo8730]

Ibrahim Quraishi I will try it soon. Thank you a lot. I have 6 cores so I need to increase the cores per socket to increase the cpu speed?.

[@ashutoshverma90]

No we can't, it's a prerequisite need to power off the VM

[@agileops]

Thanks for the response Ashutosh. The question was can we extend the virtual disk on the fly. ( when the vm is running) - In the demo I have actually extended the disk twice with out powering off the vm. and also added a new virtual disk of 10 GB (D: Drive) again without powering off the VM. As these operations are low risk we can increase the VM disk on the fly. In the coming sessions I am also going to do a demo of increasing vCPU and vMemory on the fly by enabling a feature in VMware Stetting called Hot Add CPU and Hot Plug Memory.
