[FW] Mount ASM diskgroups with new ASM instance

http://msutic.blogspot.tw/2014/10/mount-asm-diskgroups-with-new-asm.html

 

List Oracle ASM disks mounted to new server.
With "scandisks" command I will find devices which have been labeled as ASM disks.

# oracleasm scandisks Reloading disk partitions: done Cleaning any stale ASM disks... Scanning system for ASM disks...   # oracleasm listdisks DISK1 DISK2 DISK3 DISK4 DISK5 FRA1

Install "Oracle Grid Infrastructure software only" option to avoid automatic Oracle Restart and ASM configuration. This configuration will be performed later manually.

After installation finished run noted perl script as root to configure Grid Infrastructure for a Stand-Alone server.
For my configuration script looks like this:

To configure Grid Infrastructure for a Stand-Alone Server run the following command as the root user: /u01/app/11.2.0.1/grid/perl/bin/perl -I/u01/app/11.2.0.1/grid/perl/lib -I/u01/app/11.2.0.1/grid/crs/install /u01/app/11.2.0.1/grid/crs/install/roothas.pl

Start cssd if it's not running.

# ./crsctl stat res -t -------------------------------------------------------------------------------- NAME           TARGET  STATE        SERVER                   STATE_DETAILS -------------------------------------------------------------------------------- Cluster Resources -------------------------------------------------------------------------------- ora.cssd       1        OFFLINE OFFLINE ora.diskmon       1        OFFLINE OFFLINE   # ./crs_start ora.cssd Attempting to start `ora.cssd` on member `asterix` Attempting to stop `ora.diskmon` on member `asterix` Stop of `ora.diskmon` on member `asterix` succeeded. Attempting to start `ora.diskmon` on member `asterix` Start of `ora.diskmon` on member `asterix` succeeded. Start of `ora.cssd` on member `asterix` succeeded.

Create parameter file for ASM instance in $ORACLE_HOME/dbs directory of Grid Infrastructure.

init+ASM.ora *.asm_diskstring='/dev/oracleasm/disks' *.asm_power_limit=1 *.diagnostic_dest='/u01/app/grid' *.instance_type='asm' *.large_pool_size=12M *.remote_login_passwordfile='EXCLUSIVE'

Register and start ASM instance.

$ export ORACLE_SID=+ASM $ export ORACLE_HOME=/u01/app/11.2.0.1/grid $ srvctl add asm -p $ORACLE_HOME/dbs/init+ASM.ora   $ srvctl start asm $ srvctl status asm ASM is running on asterix

Now notice what I see when I start ASM configuration assistant.

$ ./asmca

These are diskgroups with my database and recovery files.
Click "Mount all" to mount them all.

Install Oracle database software and create parameter file in "$ORACLE_HOME/dbs" to start database.

$ export ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1 $ export ORACLE_SID=ora11gr2   $ cd $ORACLE_HOME/dbs $ cat initora11gr2.ora *.spfile='+DATA1/ora11gr2/spfileora11gr2.ora'   $ sqlplus / as sysdba   SQL*Plus: Release 11.2.0.1.0 Production on Wed Oct 29 14:29:37 2014   Copyright (c) 1982, 2009, Oracle.  All rights reserved.   Connected to an idle instance.   SQL> startup ORACLE instance started.   Total System Global Area  668082176 bytes Fixed Size                  2216344 bytes Variable Size             222301800 bytes Database Buffers          436207616 bytes Redo Buffers                7356416 bytes Database mounted.

Database is successfully opened and you can register instance using SRVCTL command.

$ srvctl add database -d $ORACLE_SID -o $ORACLE_HOME -p $ORACLE_HOME/dbs/initora11gr2.ora $ srvctl start database -d $ORACLE_SID

Final status.
