The command given on both the nodes to make the disks available and the resultant output obtained are as following: -
# /usr/sbin/ioscan -fun -C disk
The output from this command is similar to the following: Class I H/W Path Driver S/W State H/W Type Description ============================================================================ disk 4 255/255/0/0.0 sdisk CLAIMED DEVICE HSV100 HP /dev/dsk/c8t0d0 /dev/rdsk/c8t0d0 disk

sdisk CLAIMED DEVICE HSV100 HP /dev/dsk/c8t0d1 /dev/rdsk/c8t0d1
This command displays information about each disk attached to the system, including the block device name (/dev/dsk/cxtydz) and character raw device name (/dev/rdsk/cxtydz).
CONFIGURING DISKS FOR AUTOMATIC STORAGE MANAGEMENT BEFORE INSTALLATION OF ORACLE RAC 10 g RELEASE 2 ON HPUX: Automatic Storage Management (ASM) is a feature in Oracle Database 10g that provides the database administrator with a simple storage management interface that is consistent across all server and storage platforms. As a vertically integrated file system and volume manager, purpose-built for Oracle database files, ASM provides the performance of async as ync I/O with the easy management of a file system. ASM provides capability that saves the DBA’s DBA’s time and provides flexibility to manage a dynamic database environment with increased efficiency. Automatic Storage Management is part of the database kernel. It is linked into $ORACLE_HOME/bin/oracle so that its code may be executed by all database processes. One portion of the ASM code allows for the start-up of a special instance called an ASM Instance. ASM Instances do not mount databases, but instead manage the metadata needed to make ASM files available to ordinary database instances. ASM instances manage the metadata describing the layout of the ASM files. Database instances access the contents of ASM files directly, directly, communicating with an ASM instance only to get information about the layout of these files. This requires that a second portion of the ASM code run in the database instance, in the I/O path. Four disk groups are created at CRIS namely ASMdb1, ASM db2, ASM db3 and ASMARCH. For each disk that has to be added to a disk group, enter the following command to verify that it is not already part of an LVM LVM volume group: # /sbin/pvdisplay /dev/dsk/cxtydz
If this command displays volume group information, the disk is already part of a volume group. The disks that you choose must not n ot be part of an LVM volume group. The device paths must be the same from both b oth systems and if not same they are mapped to one virtual device name.
The following commands are executed execu ted to change the owner, group, and permissions on the character raw device file for each disk that is added to a disk group: # chown oracle:dba /dev/rdsk/cxtydz # chmod 660 /dev/rdsk/cxtydz The redundancy level chosen for the ASM disk group is the External Redundancy, which had an intelligent subsystem an HP Storage Works EVA or HP Storage Works XP.

Checking to see if the volume groups are properly created and available using the following commands: # strings /etc/lvmtab # vgdisplay –v /dev/vg_rac Changing the permissions of the database volume group vg_rac to 777, and change the permissions of all raw logical volumes to 660 and a nd the owner to oracle:dba. # chmod 777 /dev/vg_rac # chmod 660 /dev/vg_rac/r* # chown oracle:dba /dev/vg_rac/r* Change the permissions of the OCR logical logica l volumes: # chown root:oinstall /dev/vg_rac/rora_ocr_raw_100m # chmod 640 /dev/vg_rac/c8t0d0s1
To enable Database Configuration Assistant (DBCA) later to identify the appropriate raw device for each database file, a raw device-mapping file must be created, as follows: Set the ORACLE_BASE environment variable: $ export ORACLE_BASE=/opt/oracle/product Create a database file subdirectory under the Oracle base directory and set the appropriate owner, group, and permissions on it: # mkdir -p $ORACLE_BASE/oradata/ # chown -R oracle:oinstall $ORACLE_BASE/oradata # chmod -R 775 $ORACLE_BASE/oradata Change directory to the $ORACLE_BASE/oradata/dbname directory. Enter a command similar to the following to create a text file that you can be used to create the raw device mapping file: # find /dev/vg_name -user oracle -name 'r*' -print > dbname_raw.conf Create the dbname_raw.conf file that looks similar to the following: system=/dev/vg_name/rdbname_system_raw_500m sysaux=/dev/vg_name/rdbname_sysaux_raw_800m example=/dev/vg_name/rdbname_example_raw_160m users=/dev/vg_name/rdbname_users_raw_120m temp=/dev/vg_name/rdbname_temp_raw_250m undotbs1=/dev/vg_name/rdbname_undotbs1_raw_500m undotbs2=/dev/vg_name/rdbname_undotbs2_raw_500m redo1_1=/dev/vg_name/rdbname_redo1_1_raw_120m redo1_2=/dev/vg_name/rdbname_redo1_2_raw_120m redo2_1=/dev/vg_name/rdbname_redo2_1_raw_120m redo2_2=/dev/vg_name/rdbname_redo2_2_raw_120m control1=/dev/vg_name/rdbname_control1_raw_110m control2=/dev/vg_name/rdbname_control2_raw_110m spfile=/dev/vg_name/rdbname_spfile_raw_5m pwdfile=/dev/vg_name/rdbname_pwdfile_raw_5m When we are configuring the Oracle user's environment, set the DBCA_RAW_CONFIG environment variable to specify the full path to this file: $ export DBCA_RA DBCA_RAW_CONFIG=$ORACLE_BASE/oradata/dbname/dbname_raw W_CONFIG=$ORACLE_BASE/oradata/dbname/dbname_raw.conf .conf
CLUSTER MANAGEMENT CONSIDERATIONS: CONSIDERATIONS: 1. CONFIGURA CONFIGURATION TION OF HP SERVICEGU SERVICEGUARD ARD CLUSTE CLUSTER R
CLUSTER MANAGEMENT CONSIDERATIONS BEFORE INSTALLATION OF ORACLE RAC 10 g RELEASE2 ON HP-UX: Oracle RAC 10 g includes its own Clusterware and package management solution with the database product. This Clusterware is included as part of the Oracle RAC 10 g bundle. Oracle Clusterware consists of Oracle Cluster Ready Services (CRS) and Oracle Cluster Synchronization Services (CSS). CRS supports services and workload management and helps to maintain the continuous availability of the services. CRS also manages resources such as virtual IP (VIP) address for the node and the global services daemon. CSS provides cluster management functionality in case that no vendor clusterware such as HP Serviceguard is used. CONFIGURATION OF HP SERVICEGUARD CLUSTER: -
