Disk striping with LVM
Disk striping with LVM is a way of creating a logical volume on multiple disks,e.g.a 3 way striped logical volume has data alloacted on three disks, each disk storing every third block of data.
Under HP-UX 10.x, the stripe size can be 4,8,16,32 or 64Kb.
Under HP-UX 11.x it can be betweeen 4 - 32768 so long as the number is a power of 2 .
The logical volume is created using the -i and -I options of lvcreate.
e.g. lvcreate -i 3 -I 32 -L 240 -n lvol1 /dev/vg01
This will stripe across 3 disks (-i 3) with a stripe size of 32Kb (-I 32)
