Here are
some tests you can run :
TEST CLIENT DISK READ SPEED
1) Read the data and write to /dev/null:
a) with tar
timex tar cvf /dev/null /dssu1
b) with bpbkar
timex /usr/openv/netbackup/bin/bpbkar -dt 0 -r 888 -nocont /dssu1 > /dev/null
2) Read the data and write to /dev/rmt/0cbn:
a) with tar
mt -f /dev/rmt/0cbn rew
timex tar cvfb /dev/rmt/0cbn 512 /dssu1
b) with bpbkar
mt -f /dev/rmt/0cbn rew
timex /usr/openv/netbackup/bin/bpbkar -dt 0 -r 888 -nocont /dssu1 > /dev/rmt/0cbn
