Solved!
Go to Solutionsymdev output?
Quick one on symdev output please, what do the following mean:
N/Asst'd , Grp'd , N/Grp'd
I have devices that are in no groups that I know of, but they have various of these listed? I'm guessing these relate to DG's, but not sure about N/Asst'd also.
Also I think I'm ok with the following, but just wanted to confirm:
SA : P DA :IT
------------
???:? NA:NA
07H:1 09A:C18
***:* 10D:C18
i.e. what is the distinction between ???:? and ***:* and NA:NA vs DA : IT
is SA : P the FA port?, so 07H:1 would be the one and only port that the device is presented to, and ***:* means multiple, but what about ???:? then?
DA: is the disk adapters on the back end I guess, so should I assume that NA:NA is for a TDEV with no specific back end allocation ?

Grp'd , N/Grp'd relate to DGs.
N/Asst'd relates to BCVs because you need to "associate" a BCV target to a device group when working with them.
for example :
# symdg create testdg
# symld -g testdg add dev AAA STD000
# symld -g testdg add dev BBB STD001
# symbcv -g testdg associate dev 110 BCV000
# symbcv -g testdg associate dev 111 BCV001
# symmir -g testdg -full -exact establish
So, BCV's should display Asst'd or N/Asst'd under the "Attribute" column in a symdev list
A ???:? relates to devices that aren't mapped to an FA port. For example, VAULT devices or TDATs (DATA Devices), under a #symdev list -all. Or, devices under a #symdev list -noport
Yes, an NA:NA is for TDEVs because they have no specific back-end allocation.[extents on a TDEV are allocated from all TDATs in the pool]
Hope this helps.
