# How to run test:
# case 1 (local disk):
# $ nobjhi=2 thrhi=2 size=1024 case=disk sh obdfilter-survey
-# instead of case=disk one can also run test as follows
-# $ nobjhi=2 thrhi=2 size=1024 OSTS="lustre-OST0000 lustre-OST0001 ..." sh obdfilter-survey
+# one can also run test with user defined targets as follows,
+# $ nobjhi=2 thrhi=2 size=1024 targets="lustre-OST0000 lustre-OST0001 ..." sh obdfilter-survey
# case 2 (network):
-# $ nobjhi=2 thrhi=2 size=1024 server_nid="<name/nid_of_server>" case=network sh obdfilter-survey
-# where, server_nid is name or ip address of system, which you want to
+# $ nobjhi=2 thrhi=2 size=1024 targets="<name/ip_of_server>" case=network sh obdfilter-survey
+# where, targets is name or ip address of system, which you want to
# set as server.
# case 3 (network and disk):
# $ nobjhi=2 thrhi=2 size=1024 case=netdisk sh obdfilter-survey
-# instead of case="netdisk" one can also run test as follows
-# $ nobjhi=2 thrhi=2 size=1024 ECHO_CLIENTS="ECHO_<osc_name> ..." sh obdfilter-survey
+# one can also run test with user defined targets as follows,
+# $ nobjhi=2 thrhi=2 size=1024 targets="<osc_name> ..." sh obdfilter-survey
#[ NOTE: It is advised to have automated login (passwordless entry) between server and
# client systems on which this test runs.]
