Missing devices while running the command "symdev"
Hi,
When i run the command (symdev list -v -output xml) my output is lots of information about devices.
But when i run a diffrent command (symcfg list -tdev -detail -output xml) i can see that there are devices that exist in the array but i didn't get the output of those devices.
When i run the command (symcfg list -DIR ALL -address -output xml) i noticed that the missing devices are mapped to (FA-1D, FA-4D) to port 32, and they have a specific addresses (tid=0; vbus=0; lun=001..008), while other devices don't have.
I need to understand why i don't see those devices in the output from the first command.
could it be that those devices are not mapped? not masked? some kind of reservation?
Is there a better command to the the full information of all the devices?
The machine model is Symmetrix VMAX200K (firmware: 5977.691)

Someone might be able to shed more detailed light on this, but what triggers me on this is the "port 32". That's a dedicated internal array port. I'm not sure if these are connections for a virtual representation of the dedicated flash disk for vaulting on the VMAX3 or if it is an internal mapping of capacity for the virtual slices HyperMax features run on, but I can assure you that you aren't missing any externally visible capacity that should be there. I suspect what you are seeing should likely be hidden from the default view of the SE output since it isn't anything you can do anything with/about.
