Considerations when using EMC CLARiiON SNAPSHOT LUNs
If you need to import the Snapshot LUN of a primary LUN to the same host as the original LUN, be aware of the following limitation.
If you are using Enclosure-based naming (EBN) with the Array Volume id (AVID) enabled, turn off name persistence during device discovery before importing the snapshot LUN to the original host.
To turn off name persistence, use the following command:
# vxddladm set namingscheme=ebn persistence=no use_avid=yes
After DDL recognizes the LUN, turn on name persistence using the following command:
# vxddladm set namingscheme=ebn persistence=yes use_avid=yes
