The best way to know on which filesystem is the dirty blocks :
determine the filsystem name :
lsvg (just to know the volume groups on the disks probably should be rootvg)
lsvg
rootvg
datavg
then :
lsvg -l VolumeGroupName
This command shows you the list of the filesystems with their Logical Volume Name :
Logical Volume Type N of Partitions Online Filesystem
hd4 jfs 3 3 1 open/syncd /
hd2 jfs 147 147 1 open/syncd /usr
hd9var jfs 8 8 1 open/syncd /var
hd3 jfs 16 16 1 open/syncd /tmp
hd1 jfs 8 8 1 open/syncd /home
Then if you type :
lslv hd1 (to check /home)
LOGICAL VOLUME: hd1 VOLUME GROUP: rootvg
LV IDENTIFIER: 00425f7b497948fe.8 PERMISSION: read/write
VG STATE: active/complete LV STATE: opened/syncd
TYPE: jfs WRITE VERIFY: off
MAX LPs: 512 PP SIZE: 16 megabyte(s)
COPIES: 1 SCHED POLICY: parallel
LPs: 8 PPs: 8
STALE PPs: 0 BB POLICY: relocatable
INTER-POLICY: minimum RELOCATABLE: yes
INTRA-POLICY: center UPPER BOUND: 32
MOUNT POINT: /home LABEL: /home
MIRROR WRITE CONSISTENCY: on
EACH LP COPY ON A SEPARATE PV ?: yes
The Stale PP are dirty Blocks on the Filesystem !
You can do that by smitty vg / smitty lv but it's obvious
