[Oracleasm-users] Cannot create diskgroup

[alan.baldo at bull.com.br]

Okay...
I have created the diskgroup, then I create my database successfully, but
after a system reboot, the ASM disk does not exist anymore...

[root at spoang002lx root]# /etc/init.d/oracleasm status
Checking if ASM is loaded:                                 [  OK  ]
Checking if /dev/oracleasm is mounted:                     [  OK  ]
[root at spoang002lx root]# /etc/init.d/oracleasm listdisks
[root at spoang002lx root]# /etc/init.d/oracleasm querydisk ASMDISK01
asmtool: Unable to open ASM disk "ASMDISK01": No such file or directory
[root at spoang002lx root]#


When I try to startup the +ASM instance:

[oracle at spoang002lx oracle]$ export ORACLE_SID=+ASM
[oracle at spoang002lx oracle]$ sqlplus /nolog

There is some persistence parameter or configuration needed by ASMLib?
