RDM

[vmb01]

I'm investigating on how a VM points to a Physical RDM

In the edit settings of the VM I see that the RDM is referred as the lun vml

In the vmdk descriptor file I do not see this vml and I do not see any reference to the vml or to the physical lun, in this file I see:

# Disk DescriptorFile

version=1

encoding="UTF-8"

CID=f25ac798

parentCID=ffffffff

isNativeSnapshot="no"

createType="vmfsPassthroughRawDeviceMap"

# Extent description

RW 20971520 VMFSRDM "win2k3ENT_1-rdmp.vmdk"

# The Disk Data Base

#DDB

ddb.adapterType = "lsilogic"

ddb.geometry.sectors = "63"

ddb.geometry.heads = "255"

ddb.geometry.cylinders = "1305"

ddb.uuid = "60 00 C2 95 1a c9 6a 86-16 06 89 69 5c 69 d2 63"

ddb.longContentID = "1e2e791f1ed1b8c3df53498bf25ac798"

ddb.virtualHWVersion = "8"

Which are the metadata that point to the physical lun?

Thanks in advance

vml is legacy naming when the naa t10 names are not available.  You can see which device is assotiated with vml

esxcli  storage core device list

naa.number

Display Name: DGC Fibre Channel Disk(naa.number)

...

Other UIDs:vml.number

Thanks,

I need to understand wich is the 'link' between the disk descriptor file and the physical LUN pointed.

Which field inside the file is referring the  physical LUN ?
