Why does Voting File is different in different nodes [message #615266]

Initially I have a one node RAC, later, in $GRID_HOME, the initohasd files is missing, so I've to deconfigure the clusterware and reinstall $GRID_BINARIES, in the process I also drop the diskgroup that contains both Voting disk and OCR. What happens is that I empty the disk before marking them with oracleasm libraries, i.e. /etc/init.d/oracleasm create disk OCR_VOTE 1 /dev/asm-ocr-vote1_part1.

Before I deconfigure the clusteware, I've used udev to mark the disk.

So after resintalling the grid binaries, I found some unexplained observations.

On my first node

Code: [Select all] [Show/ hide]

grid@ORCL01:~> crsctl query css votedisk
##  STATE    File Universal Id                File Name Disk group
--  -----    -----------------                --------- ---------
 1. ONLINE   3cf0990ca73f4f58bf18bcb9874524be (ORCL:OCR_VOTE1) [OCR_VOTE]
Located 1 voting disk(s).

on my second node

Code: [Select all] [Show/ hide]

grid@ORCL02:~> crsctl query css votedisk
##  STATE    File Universal Id                File Name Disk group
--  -----    -----------------                --------- ---------
 1. ONLINE   3cf0990ca73f4f58bf18bcb9874524be (/dev/asm-ocr-vote1_part1) [OCR_VOTE]
Located 1 voting disk(s).
grid@ORCL02:~>

Why is it in the second node it is reflecting the old udev path and not the oracleasm lib path (ORCL:OCR_VOTE1)

many thanks in advance!

If this question still open.. Can you provide the details from both node ?

Code: [Select all] [Show/ hide]

set linesize 120
select MOUNT_STATUS,HEADER_STATUS,MODE_STATUS,STATE,name,path from v$asm_disk

/etc/oracleasm/querydisk <<diskname>>

I would like to see major / minor number from both node.

It seems your major / minor numbers are different but this can't be same from storage level.. Why don't you check with your storage team for above shared device ?

In my experience few environment I do see the different major / minor numbers but as per my storage admin.. " Those lun's uniqe ID was same from storage clarrion but in server its shows different ID.. "

thanks, Babu
