1. Click ----Additional Tasks---- and select Volume Parameters.... A dialog box similar to the one
in Figure 84 is displayed, which is an example of an LVM volume.

2. Modify the following values as needed:
Cont Alloc: This sets the contiguous allocation policy. A contiguous logical volume
has these characteristics:
• Physical extents are allocated in ascending order.
• No gap is enabled between physical extents within a mirror
copy.
• Physical extents of any mirror copy all reside on a single physical
volume.
• The root volume (/), the boot volume (/stand), dump volumes,
and primary swap must always be created with Cont Alloc set
to Yes.
Stripes:... If two or more disks are in the volume group, then you may enable
data striping over multiple disks for performance purposes.
Stripe Size: Configure this if you have at least two disks in a volume group. The
first drop-down allows you to configure the unit, and the second
drop-down allows you to configure the size. The default stripe size
is equal to the file system block size, which is normally 8 KB.
B-block Relo: Bad-block relocation is a mechanism that, when a disk defect is found,
attempts to relocate the failing block to another location on the disk.
This is the default behavior when a logical volume is created though
it is not supported for root, swap, or dump logical volumes.
Vol Name: Enter the name you want for the selected volume.
Disk Mapping... Displays a dialog box that enables you to restrict the disk drives on
which the volume data will reside. Normally, the data will be
allocated over these disks sequentially.
For more information, see lvcreate(1M) for LVM or vxassist(1M) for VxVM.
