LUN presented to ASM but asm cannot see it as candidate
ORACLE DB: 11.2.0.3
ASM
RAC: 4 nodes
per system admin, he has given a lun for FRA but when I run ASMCA to add this lun to FRA DG, the add disks screen does not show this LUN as Eligible. When I click "Show All", the lun shows up and a Header Status as MEMBER and not Candidate.
When I query the v$asm_disk table, this lun shows as following:
1. Mount_status = Closed
2. header_status = Member
3. Mode_status = normal
4. Name = BLANK
5. Failgroup = BLANK
****** This is what I got from the System Admin ********
Here is a test to show oracle can access the devices:
