HP-UX - How to convert HP strict/distributed Volumes to Normal

Post  Admin on Thu Jun 24, 2010 1:40 am

To turn off the Distributed allocation policy:

# lvchange -D n /dev/vg02/lvol1

That can be done online. After that you should be able to do your lvextend.


Change the allocation policy of a logical volume to nonstrict:

# lvchange -s n /dev/vg01/lvol7

HOST2@root:/> lvdisplay -v /dev/vgsap/test |more
--- Logical volumes ---
LV Name /dev/vgsap/test
VG Name /dev/vgsap
LV Permission read/write
LV Status available/syncd
Mirror copies 0
Consistency Recovery MWC
Schedule parallel
LV Size (Mbytes) 24784
Current LE 3098
Allocated PE 3098
Stripes 0
Stripe Size (Kbytes) 0
Bad block NONE
Allocation PVG-strict/distributed
IO Timeout (Seconds) default

--- Distribution of logical volume ---
