hi
all,
By observing the onstat -d output , it shows less than 2 % of lldbs and
phydbs are free.i Have set my LTAPEDEV to /dev/null
but still it shows the same .
do i need to add extra chunks to lldbs and phydbs

Hi,
i think that's OK ! Normaly the logdbs and physdbd are filled
to 100%.
ciao,
Thomas

No, there is no need to add chinks to these (unless you need to create any
more logical logs). The physdbs (I assume from the name) holds the physical
log which is fixed in size (in the onconfig file) and will not vary (unless
you change the onconfig). The lldbs (again assuming from the name) holds the
logical log files which again will not vary (unless you need to create more
logical logs).
If you have a history of onstat -d output (useful to see how quickly and by
how much free space is disappearing) you will see the free space in these
spaces do not vary.
