At our work place we have two datacentres and each DC has an HDS SAN. The idea is that I put two cluster nodes in each DC and each node will be presented with two multipathed block devices say /dev/dm-5 and /dev/dm-6. How can I create 2 mirrored LVs out of a volume group {comprising the two devices} and assuring that the mirrors are spread between the two devices {to give me the assurance that if one DC is down, data is available in the other device}

Hi Konrad,
it is as simple as:
# lvcreate -L $SIZE -m1 -n $LV $VG $PV1 $PV2 ...
The "$PV1 $PV2" part does the trick.
See man lvcreate and search the web for details.
