For example, we have a VMware environment with a host of the runtime ESXi, with 10 SAS disks on it. The five discs in these 10 disks were RDM to a virtual machine. Suppose you find that you have added a piece of disk and you want to remove it, but 5 of the disks have 3 discs already in use (i.e. they have production data on them). However, in the VMware Virtual Machine Properties dialog box, you can only see hard disk X, physical LUN and Datastore Mapping file numbers do not seem to work, how to do?
First you need to know by other means the name of the device of the disk you want to delete, and this name will appear in the storage option under the Configuration tab of host.
Find the device and record his identifier.
Here is a string of strings at the end of the 22a09.
Then to the virtual, copy all the physical LUN and Datastore Mapping file string, select the number of the device ID as the keyword, to match.
vml.0200000000600605b0072c91001ba288d0d62ee7dd4d5239323731
vml.0200000000600605b0072c91001ba28936dc3c29b84d5239323731
vml.0200000000600605b0072c91001ba2880aca622a094d5239323731
vml.0200000000600605b0072c91001ba2889cd31a3a044d5239323731
In this way, we find the RDM disk that we want to remove.
That is, the physical LUN and Datastore Mapping file string is part of the device's ID.
In VMware vcenter, how can I identify a piece of physical disk that the raw Device mapping over on a virtual machine?
