ASM lun/disk not mapped

Vinay KSep 22 2015 — edited Sep 23 2015

Linux 6.4

oracle 11.2.0.4, 2 node RAC

I need to add a fresh disk to the DG

Storage team has given a lun as below under /dev/mapper

lrwxrwxrwx 1 grid asmadmin 8 Sep 22 13:05 CDISC02 -> ../dm-19

This is not visible in oracle as candidate.

Existing disk are also listed under - /dev/oracleasm/disks/

brw-rw---- 1 grid asmadmin 8, 32 Sep 22 21:23 FRA

brw-rw---- 1 grid asmadmin 8, 16 Sep 22 21:23 DATA01

brw-rw---- 1 grid asmadmin 8, 80 Sep 22 21:23 QUORUM

I want this new lun as DATA02; How can i guide the SA to create DATA02 from the above lun.

Is this some kind of device mapping which is missing ?

please help.
