A nomount dbua instance sitting on our DR server?

I was getting ready for a storage refresh on one of our DR servers when I saw a 
database instance I was unfamiliar with named DBUA2758156. From the name I 
assume it is something associated with the database upgrade assistant but I 
have no idea what. It is in nomount mode, has been running for 5 days and has 
an orapw and init.ora file (also with a timestamp from 5 days ago) but no entry 
in /etc/oratab. Googling and searching metalink just turns up a bunch of DBUA 
documentation.

I'm tempted to just try shutting it down but since I've never seen anything 
like this before I opened an SR and thought I'd check if anyone here had seen 
anything similar.

This is the init.ora file:

db_name=DBUA2758 
db_unique_name=DBUA2758156 
shared_pool_size=128m 
cpu_count=1 
diagnostic_dest=/app/oracle/product/11.2.0.3/log 
_enable_NUMA_support=false
