PRKS-1023 : Failed to remove CRS resource for ASM instance "ASM1" on node "mir1", [CRS-0214: Could not unregister resource 'ora.rac1.ASM1.asm'.]]

Problem:

PRKS-1023 : Failed to remove CRS resource for ASM instance "ASM1" on node "mir1", [CRS-0214: Could not unregister resource 'ora.mir1.ASM1.asm'.]]

Cause: Normally it happens when you delete DB before deleting ASM instance.

Solution:
Find out the exact name for service:
# crs_stat grep asm

Stop service using:
# crs_stop ora..ASM(#).asm
(For ex.: # crs_stop ora.rac1.ASM1.asm)

Delete service with force using:
# srvctl remove asm -n -f
(For ex.: # srvcl remove am -n rac1 -f

Goodbye headache!!! :D
