Logical volume

Kosmider — Thu, 06 Apr 2006 07:58:36 GMT

I have Virtual Array VA7400, HP-UX 11.00.
There are two Redundancy Groups: RG1, RG2 on this VA7400.
Can I create logical volume on two LUNs ?

You can create a volume group that spans multiples LUNs or physical disk, then create a logical volume in this volume group. As results, the logical volume will use both disks.

Yes!

Easily use SAM and stripe the LVOL over the LUNS for performance!

For example:

# Create a Volume Group with two disks or lunx

vgcreate /dev/vg01 /dev/dsk/c3t0d0 /dev/dsk/c4t0d0

# Create the logical volume with size of 500 GB, stripped across 2 disks with a stripe size of 64 KB

lvcreate -L 500 -i 2 -I 64 /dev/vg01
