Developing striped logical volume strategies
Striped logical volumes are used for large sequential file systems that are frequently accessed and performance-sensitive. Striping is intended to improve performance.
Note: A dump space or boot logical volume cannot be striped.
The boot logical volume must be contiguous physical partitions.
To
create a 12-partition striped logical volume called lv07 in VGName
with a strip size (the strip size multiplied by the number of disks
in an array equals the stripe size) of 16 KB across hdisk1, hdisk2,
and hdisk3, type:
mklv -y lv07 -S 16K VGName 12 hdisk1 hdisk2 hdisk3To
create a 12-partition striped logical volume called lv08 in VGName
with a strip size of 8 KB across any three disks within VGName, type:
mklv -y lv08 -S 8K -u 3 VGName 12For more information on how to improve performance by using disk striping, see Performance management.
