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.

3.Click Modify to implement all changes.

4.When you have finished modifying all values, click OK to return to the File System tab.
