Cannot extend logical volume
Dear All,

We have an Oracle running on AIX 6.1, now there have an disk spaces issue and we found that we cannot perform to extend the logical volume. Could help to review and make some suggestions.

Status:
we already provisioned some disks to the host, new disks can be scan and add into the volume group, issue just happened during extend the logical volume.

we try to use chlv -x 72174 oravol used PP is 63984, new PP is 8190.

Is that related to the policy "striped" not "parallel"?

Thanks.

Code:
# lslv oravol
