This appendix includes the following topics:

■ Migrating to thin provisioning

Migrating to thin provisioning

The SmartMove™ feature enables migration from traditional LUNs to thinly

provisioned LUNs, removing unused space in the process.

To migrate to thin provisioning

Turn on the SmartMove feature. Edit the /etc/default/vxsf file so that

usefssmartmove is set to all.

usefssmartmove=all

Add the new, thin LUNs to the existing disk group:

# vxdisksetup -I da_name

# vxdg -g datadg adddisk da_name

where da_name is the disk access name in VxVM.

If enclosure based naming (EBN) is enabled and the disk accesss name is

displayed, enter:

# vxddladm set naming scheme=ebn

To identify thin LUNs, enter:

# vxdisk -o thin list

Add the new, thin LUNs as a new plex to the volume.
