Error Message
ERROR V-5-1-7001 Volume SNAP-fsfr1-phip1-01 cannot be refreshed from the volume fsfr1-phip1-01 due to size/regionsize incompatibility
Resolution
# vxassist -g datadg make volgunnum 400m logtype=dco dcoversion=20 fastresync=on regionsz=128
# vxassist -g datadg make SNAP-volgunnum 400m logtype=dco dcoversion=20 fastresync=on regionsz=256

VxVM vxsnap ERROR V-5-1-7001 Volume SNAP-volgunnum cannot be refreshed from the volume volgunnum due to size/regionsize incompatibilityCheck status of region size for the DCO for each volumes

# vxprint -g datadg -m SNAP-volgunnum_dco | grep regionsz
256
The original Volume has region size of 128 while Snap_volume has region size of 256. To resolve this issue specify regionsize to be the same for both the original volume and the snap_volume) when creating a new volume/snap_volume. For example for the snap volume = SNAP-fsfr1-phip1-01 , instead of using
# vxassist -g nasdg make SNAP-fsfr1-phip1-01 419718464 layout=concat logtype=dco dcoversion=20 fastresync=on nashrdg10b
specify the regionsize=256 to match the regionsize for the original volume = fsfr1-phip1-01 :
# vxassist -g nasdg make SNAP-fsfr1-phip1-01 419718464 layout=concat logtype=dco dcoversion=20 fastresync=on regionsz=256 nashrdg10b
