I am setting up 2 node RAC 12.1.0.1.0, below is the storage details:
Disk /dev/sda: 6594.0 GB, 6594041479168 bytes
255 heads, 63 sectors/track, 801679 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 1048576 bytes

similar to above I have below storage each 6TB
/dev/sdb
/dev/sdd6
/dev/sde6
/dev/mapper/mpathb
I just want to use /dev/sda, but when I created VOTE1 disk:
oracleasm createdisk VOTE2 /dev/dm-4
under VOTE1 I can see all disks:
[root@som-orclracdb01 log]# oracleasm querydisk -p VOTE1
Disk "VOTE1" is a valid ASM disk
/dev/sda5: LABEL="VOTE1" TYPE="oracleasm"
/dev/sdb5: LABEL="VOTE1" TYPE="oracleasm"
/dev/sdd5: LABEL="VOTE1" TYPE="oracleasm"
/dev/sde5: LABEL="VOTE1" TYPE="oracleasm"
/dev/mapper/mpathbp5: LABEL="VOTE1" TYPE="oracleasm"
this is one issue & another problem is I am unable to see VOTE1 disk on second node, I created another VOTE2 disk on second node which is not visible on first node.
I tried setting
ORACLEASM_SCANORDER="dm"
ORACLEASM_SCANEXCLUDE="sd" but no luck , can someone please help
