Virtual TPM and physical TPM

MRoushdy — Sat, 23 Apr 2022 16:45:05 GMT

Hello,

I'm interested in learning more about vTPM and I have the following questions please:

since it's virtual, where are the keys being stored then, in a file?
does the vTPM require that the physical server has a physical TPM chip? if the answe is "Yes", how would that work with vMotion?

Thank you,

Re: VMHost average Compute consumption for one day

MRoushdy — Mon, 21 Dec 2020 10:55:22 GMT

Thanks a lot. what's the possibility of having also the average of memory, along with the host name please?

I'm using this format:

foreach {$i in $host1) { get-VMHost -Name $i | Get-Stat -Start (Get-Date).AddDays(-1) -Stat 'cpu.usage.average' | Measure-Object -Property Value -Average |Select -ExpandProperty Average }

Simpler in the use I meant .>> I just want to generate a report of the average of each ESXi host, with a single value, not the average for each day, if I specified a range of days I mean. I hope it's a bit clear now, and pardon me if I'm mistaken about something.

VMHost average Compute consumption for one day

MRoushdy — Wed, 16 Dec 2020 09:29:02 GMT

Hello,

Just to have the average for thelast 24 hours for CPU and memory consumtpion on VMhosts.

Thus article by LUCD https://www.lucd.info/2010/01/05/powercli-vsphere-statistics-part-2-come-together/ is awesome, but I needed something much simpler.

Thanks,

Thanks Boss

get harddisk sharing mode, and storage policy

MRoushdy — Tue, 29 Sep 2020 09:01:27 GMT

Hello,

I have two inquiries please:

1- I 'm creating a lot of VMDKs, and I need a simple command to enable "multi-writer" mode. I came across a complicated script that I have no time now to tune ot, so, I hope I get a simple command to achieve this.

2- I need to query the disks and list )select) their sharing mode, and current storage policy.

Thank you,

get thin VMDK actual size on datastore

Hello,

I need to get-harddisk used space on the datastore please, not the provisioned space.

Thank you,

I will try them tomorrow and let you know the result.

Be safe!

stop a service using GET-ESXCLI

MRoushdy — Sun, 29 Mar 2020 12:25:48 GMT

Hello,

I'd like to use get-esxcli to run the following command, I also need to run it against specific clusters, or maybe by importing from a CSV file please.

esxcli system wbem set --enable false

Thank you,

Re: "Lost Access To Volume" - tons of error messages

MRoushdy — Sun, 23 Feb 2020 11:59:46 GMT

Thanks. I've gone through the KB, and we are still using VMFS5 datastores, but we are planning to upgrade to VMFS6 very soon. I will check with NETAPP anyway. Thanks again.

"Lost Access To Volume" - tons of error messages

MRoushdy — Sun, 23 Feb 2020 11:11:13 GMT

Hello,

I get like 1 thousand error messages everyday about losing connections to datastores, I thought it's just a bug in ESXi 6.0, and it will go after upgrading to 6.7, but this didn't happen, IO still get the same message after deploying a fresh installation of ESXi 6.7. We have many HPE server models, and many NETAPP enterprise SAN storages, connected via eight Brocade 6510 switches, and neither the storage systems, nor the SAN switches report any issues or latency issues. Also, VMware support has confirmed that all of the H/W drivers are compatible with the hardware and firmware versions.

I can't tell if we are facing performance issues or not, but mostly not, and I'm intending to perform a SAN fabric reboot to test the paths from servers to SAN, but with these errors I wont.

Has anyone faced the same issue please?

Thank you,

This is great, thank you. However, I need the report to include the ESXi hostname if you know how to .

Hello,

I need to query all ESXi hosts against "lost access to volume" for datastore issues over a certain period of time please. How?

Okay, though, not working at all I've verified the names an they are still the same.

Re: Appending Datastore Name

MRoushdy — Thu, 05 Dec 2019 09:25:46 GMT

Thanks, but, where should I declare the var "$_.nfsname" ?

Appending Datastore Name

MRoushdy — Thu, 05 Dec 2019 08:44:31 GMT

Hello, appending a single datastore works fine, but, appending a list from CSV didn't work fine with me. I used this example:

Get-Content ".\rename-ds.csv" | ConvertFrom-Csv -header nfsname | %{get-datastore $_.nfsname } | Set-Datas
tore -Name $nfsname"-DONTUSE"

This script did the trick for me.

Export Vms with replication configured

MRoushdy — Mon, 04 Nov 2019 11:30:26 GMT

Hello,

I understand that vSphere Replication has no API interface, but I need to export a list with all vSphere Replication jobs, so, is there a way to query VMs with replication configured against vCenter server?

Re: using "foreach"

MRoushdy — Wed, 09 Oct 2019 10:21:26 GMT

That did the trick, but I wanted also to seize the opportunity to learn about "foreach" with PowerCLi.

Thanks,
