Oracle Database Discussions

Hi,

I have sles11x86_64 installed and using Veritas Volume manager raw disks for ASM but ASM dg creation fails with error mentioned below;

ls /dev/vx/rdsk/asmdg/asmvol
/dev/vx/rdsk/asmdg/asmvol
test:~ # ls -l /dev/vx/rdsk/asmdg/asmvol
crw-rw---- 1 oracle oinstall 199, 65533 Feb 26 12:08 /dev/vx/rdsk/asmdg/asmvol
test:~ # su - oracle
oracle@test:~> bash

# Entries are of the form:

# The first and second fields are the system identifier and home

# Multiple entries with the same $ORACLE_SID are not allowed.
