    Yes, those set.N items are related to the install locations HD1.N. If you want to destroy one, you can issue "tmsh delete sys software volume HD1.N", either in the guest or the host, wherever you're trying to eke out more free disk space.

those are for the host only. vCMP guests are in the volume

ACTIVE '/dev/vg-db-sda/app.vcmp.dat.vmdisks' [276.72 GB] inherit

With df, you will see 100G per guest, which looks like to be "reserved" space. 

tmsh  show vcmp virtual-disk detail
shows the effective disk usage per guest

Diskspace on vCmp system is scarce. I would recommend to use no more than 2 volumes per guest (and on the host)
