Hi Gary, Once the new SAN LUNs were presented to us, I just marked them as physical volumes, extended the VG, then pvmove'd the old PVs to the new ones. We had 3 existing LUNs that were moving to 1 larger LUN on the new SAN.
pvcreate /dev/mapper/mpath4 vgextend datavg /dev/mapper/mpath4 pvmove -b /dev/mapper/mpath1 /dev/mapper/mpath4 pvmove -i 2 (to watch the progress) pvmove -b /dev/mapper/mpath2 /dev/mapper/mpath4 pvmove -i 2 (to watch the progress) pvmove -b /dev/mapper/mpath3 /dev/mapper/mpath4 pvmove -i 2 (to watch the progress) lvdisplay -m /dev/datavg/* | grep "Physical volume" (only mpath4 shows) vgreduce datavg /dev/mapper/mpath1 /dev/mapper/mpath2 /dev/mapper/mpath3 pvremove /dev/mapper/mpath1 /dev/mapper/mpath2 /dev/mapper/mpath3 The only difference with the clustered systems was that the cmirror package needed to be installed and the clogd daemon running.
