puoi probabilmente usare i vari tool che fanno immagini ma come ti dicevano sopra, la cosa migliore è salvare la configurazione e tenersi da parte una ISO di installazione di ESXi con la stessa bulid che hai attualmente.

In caso di disastro ripristini il disco fisico, installi ESXI da zero (ci vuole poco!) e poi gli carichi la configurazione salvata. Fai mooolto prima e sicuro

Re: Weird disk latency issue on new R760 with onboard storage. Please help.

hi, it sounds really strange and I don't think shere is something wrong with the hypervisor.

If the machine is not yet in production, you could try maybe with a linux live cd and test the virtual volume performance (i guess you'll need to destroy the current datastore and forma in a linux usable filesystem)

after you add an hard disk you need to force the operating system to rescan the SCSI Bus. The easiest way is to reboot, but you can find many tricks on the internet to do it without rebooting

Re: Interesting observation with two enivornments using the same SAN

first of all, you no longer need shared storage to perform VM live migrations.

Finally, the only "one" who can automatically restart a VM on another host is the vSphere HA

A standalone host, even if it can access the VM directories and files, will never register (take ownership) of VMs until some one clicks on the .vmx file and issue the register command.

And more: if the host is under the same vCenter of the "legal" owner of the VM, the register operation will fail.

Re: caccia allo snapshot (VM needs consolidation)

ciao, in quel caso si trattava di NetWorker, ma penso possa capitare un po' con tutti i software. Capitava anche con Veeam, poi hanno introdotto questa funzione: Snapshot Hunter

In generale è importante avere un qualcosa che ti avvisi in caso di snapshot dimenticati (e di datastore che si riempiono). Molto spesso, anche in contesti grandi, ho visto trascurare questo controllo, spesso con danni, perdite di tempo e cene rovinate.

Sono di parte perché ci lavoro come partner ma... Veeam One

anche in versione community e gratuita, svolge perfettamente questo compito

Re: License downgrade 8.0 -> 6.0

where did you find this "incompatibility"?

if you have found it in the VMware Compatibility Matrix

it does not mean that ESXi7 won't install

Tinto, you miss the point that ESXi7 will not install on a R610 server

are you sure about that or you suppose it?

Finally: the answer to your question is NO: vsphere 6 is "out of sale" since 2020.

Sorry if i was trying to suggest a workaround, please forgive me

Re: License downgrade 8.0 -> 6.0

Tinto1970 — Tue, 11 Jul 2023 12:28:47 GMT

https://lifecycle.vmware.com/#/

end of availability of version 6 is gone (3 years ago)

once again: it's not important if "PowerEdge R610 certified by Dell up to ESXi 6.0 at maximum": you/your customer will be ANYWAY out of support.
I see no higher risks in using an out of support ESXi7 instead of an out of support ESXI6. But lower risks instead...

Re: Upgrade path

Tinto1970 — Tue, 11 Jul 2023 10:28:09 GMT

hello, in short: upgrade from u3g to u3n directly. It's a really minor update.

In general, take a look at this Upgrade Paths

Hi @AnaghB ,

Thank you for the info, upon checking, the hardware acceleration is not supported. Is there a workaround to enable the thick provision?

Btw, I'm using IBM Cloud Storage for my VMware datastore.

I think no. But you can use the thin disk, this will not affect performance. Just monitor your storage to put under control or avoid overprovisioning

Re: HDD Capacity Calculator

Tinto1970 — Tue, 11 Jul 2023 10:15:06 GMT

If I understand well, you have two 1.9TB drives in RAID1 configuration, and the datastore free space is "only" 1.6TB?

If so, I think it's normal because the 1.9 size is "unformatted": the really usable size of the HDD is less than the "raw" amount which is written on the HDD's box

Re: License downgrade 8.0 -> 6.0

Tinto1970 — Tue, 11 Jul 2023 10:10:16 GMT

but are you sure that ESXi 7 cannot install on the hardware? Did you try?

a good advice is to be reluctant to let the SAN run for many years without an update

Re: Sharing datastore cluster between ESXi 7.0.3 Clusters for VM Migration

Tinto1970 — Tue, 11 Jul 2023 09:27:28 GMT

yes it's supported. But keep in mind that live VM migration is supported also without shared storage.

Re: License downgrade 8.0 -> 6.0

Tinto1970 — Tue, 11 Jul 2023 09:24:40 GMT

6 months of an old and unpatched system is not as short time... anyway I think you should get in contact with a VMware sales representative and ask him/her fi they can help you.

And, let me ask: why do you want to " license an old hardware with esx 6.0 as maximum supported version" if there is NO support?

In other words: you will be out of support both with esxi 6 and 7: why don't you try upgrading to ESXI 7?

Re: License downgrade 8.0 -> 6.0

Tinto1970 — Tue, 11 Jul 2023 09:04:58 GMT

sorry, i guess no, no way. The Licensing page in your MyVMware site should not allow you to do so. Give it a try, but I'm pretty sure.

You could try to buy a "second hand" old license of vSphere 6: the key should work but you probably know the contras of using an out of support software, even in labs or non production environments.

Re: Interesting observation with two enivornments using the same SAN

Tinto1970 — Tue, 11 Jul 2023 08:44:07 GMT

hi, first of all it would be better that old hosts could not see datastores they don't have to use

anyway I don't understand... are you saying that the old 6.5 hosts have registered "automatically" VMs that were not present in their Inventory?

It sounds reeealy strange...

Re: vCenter/Photon OS Passwortreset

Tinto1970 — Tue, 11 Jul 2023 08:29:22 GMT

Hallo, Ich habe nicht gut verstanden das Problem.

Sie müssen auf die Webkonsole (oder Remote Console) der vCenter VM zugreifen, um das Verfahren durchzuführen.

Was passiert? Können Sie bitte einen Screenshot der Webkonsole hier posten?

Danke

ciao, più che una domanda volevo condividere un mio breve articoletto in cui racconto come ho fatto a scoprire la causa di uno quel maledetti "VM consolidation needed" che non se ne volevano andare via... perché qualcuno aveva "rapito" il disco alla VM in questione.
