"host_mo_ref.config.storageDevice.plugStoreTopology.device.lun" returns nil

[Cindia-blue]

try to get key of mapped Lun device by calling host_mo_ref.config.storageDevice.plugStoreTopology.device.lun, but keep got nil. according to VIM development guidence, this should return an object of Lun(ScsiLun). should I change to some other way with Rbvimomi function invocation to reach the goal? Looking forward to suggestions on this problem and sharing of best dev practice with Rbvmomi.

Go to https:///mob and browse through there to find the same thing. Does it show up there?

[Cindia-blue]

yes, on mob web page I can find values which failed to be returned by rbvmomi, e.g. for host_mo_ref.config.storageDevice.plugStoreTopology.device.lun, mob page presents the key of mapped lun object but rbvmomi returns nil

[cdickmann]

Is this value one that was introduced in a later API version, like ESX 5.0 or 5.1? If so, you need to make rbvmomi connect with that API revision.

[Cindia-blue]

yes, this is included by vSphere 5.0 Management SDK. Would you please help provide guidance about how to make rbvmomi connect with right API revision?

[cdickmann]

When you connect, you can set :rev. After connect, you can do "conn.rev = ". Set it to 5.0. I believe RVC has the nice code to negotiate the highest possible version with the server.

Thanks for the help. Progress has been made on reachable of deep object but can not get any of its properties. below is my code and returns: plug_devices = host_mo_ref.config.storageDevice.plugStoreTopology.device puts "plug_devices lun is #{plug_devices[0][:lun].inspect}"

return: plug_devices lun is #<RbVmomi::VIM::ScsiLun:0x23a3df8 @props={:dynamicProperty=>[], :descriptor=>[], :alternateName=>[], :standardInquiry=>[], :operationalState=>[]}>

looking forward to further comments. Thanks.

@Cindia-blue Hey, I just started maintaining this project and noticed this issue is almost 4 years old. Is this still something you'd like me to look into or is this ok to close?
