Hi Jose,

The LUN collision is shown against those devices as they might be bounded to the same WWLUNID being hold by previous devices.

It might be a case the previously created LUNs are un-presented but the devices are not deleted and same LUNs are presented again OR the old devices are in use and LUNs are presented again?

Check the LUNs configuration using
# autopath display
# autopath display
