I think I've also seen recommendations against that in some recent threads here.

I've not seen that.

It looks like I have a little work to do. Our host has two NWSD's configured for each guest. From their descriptions it looks like one of each pair was intended for disk and the other for tape. But they're both configured with ALWDEVRSC(*UNRSTD) RSTDDEVRSC(*NONE). I wish we could virtualize our tape library. But, from a document linked to in another recent thread, with our tape library and SAS controllers we would only be able to virtualize the library in serial mode. We'd loose all the library functionality.
We have three guests, and multiple optical drives appear on each guest. The host has one physical and one virtual optical drive. Each guest has three or four type 632C virtualized optical drives showing up. One guest has one optical drive with type *OPT. And each guest has one type 632B virtual optical drive, which I think is local to each guest, not virtualized.
On this page:
https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_74/rzam4/rzam4clientvirtdevices.htm
it says:
If you define multiple Network Server descriptions, then you must use
the RSTDDEVRSC or ALWDEVRSC parameters to prevent the same device from
appearing multiple times on the client partitions.
I think I've also seen recommendations against that in some recent threads here. Is there a better way to prevent the same device from appearing multiple times on the guest partitions?
