Look at the line in red and blue it holds the answer.
I had a look under $ORACLE_HOME/dbs and tried to find initdev1tstp1.ora file to see the contents and those were +DATA/dev1tst/spfiledev1tstp.ora . When I had a look at the database on primary side its db_unique_name is dev1tstp and that is the directory on ASM as well.
Let me try to explain the message a little bit
ORA-19505: failed to identify file "+DATA/dev1tst/spfiledev1tstp.ora"
ORA-15173: entry 'dev1tst' does not exist in directory '/'
What oracle is trying to inform is that for entry 'dev1tst' there is no such directory under "+DATA", please note that '/' is little misleading here and you could end up looking on file system but actually it was on ASM in my case.
After fixing the init file to the one below, that error disappeared.
[oracle@tser01n01 (dev1tstp1) dbs]$ cat initdev1tstp1.ora
SPFILE='+DATA/dev1tstp/spfiledev1tstp.ora'
[oracle@tser01n01 (dev1tstp1) dbs]$
