Hi srvdev，

We are currently experiencing a related problem, so I came to ask you if you have found a way to do this? By the way, I would also like to ask you how you send the request to the SDK?

Questions about physical address vm disk mapping

25421 — Mon, 06 Nov 2023 06:07:27 GMT

Hi, everyone. It's me again.

Previously I learned that the vmkfstools command can get information about the mapping blocks of virtual disks on physical LUNs, and in recent days when I was using veeam to do backups, I found such a file: *****_mapping.xml, which was deleted after the backups were completed, so I found a chance to download him, which really surprised me, and in the following days, I tried to analyze the structure of the file content, and found that he was the same as the data block area obtained using vmkfstools! It just contains a bit more comprehensive information, I guess there should indeed exist some interface to get the relevant data structure.

So I found the following article:API HostDiskManager Endpoint / AcquireLeaseExt - VMware Technology Network VMTN

Now I have the same doubt as the author? I would like to discuss how the SOAP request in the article should be called?

PS: The documentation appendix on mapping is below, so I won't post it here.

Re: Is there a publicly available API to get the mapping of virtual disks on physical LUNs?

Indeed, that's the API I found from an article about Aria Operations (formerly vRealize Operations), but unfortunately I don't have that product, maybe I can look more closely in that way. Thanks for the suggestion!

Is there a publicly available API to get the mapping of virtual disks on physical LUNs?

Being in a development need recently, I learned that the hidden command vmkfstools -t 0 gets the mapped blocks of virtual disks on physical LUNs:

[ 0: 117440512] --> [VMFS -- LVID:651285d2-46059dc2-1ac2-b4055d862ec5/651285d1-13ef519c-16f4-b4055d862ec5/1:( 358648643584 --> 358766084096)]

Also learned what the various parts of this represent, but alas, I wish there was a relevant API to get at this information, and I found some other people's solutions in the discussion, but I'm sorry it's too far back in time for me to get any useful information out of it. The only thread of interest was this one: vim.hostblockinfo.vmfsmapping

I'm wondering if VMware makes this API publicly available and if I need some other way or a partnership with VMware to be able to use it? Thanks in advance for any help here!
