Configuring Oracle ASM For proper functioning with Linux hosts using Oracle ASM with PowerStore, configure the Oracle ASM settings file. Prerequisites For a PowerStore cluster to function properly with Linux hosts that are using the Oracle ASM volume management software, follow these steps to configure the /etc/sysconfig/oracleasm settings file: Steps 1. Modify the following lines in the /etc/sysconfig/oracleasm file according to the multipathing used on the host: # ORACLEASM_SCANORDER: Matching patterns to order disk scanning ORACLEASM_SCANORDER="" # ORACLEASM_SCANEXCLUDE: Matching patterns to exclude disks from scan ORACLEASM_SCANEXCLUDE="" • When DM-MPIO multipathing is used on the Linux host, edit these lines as follows: # ORACLEASM_SCANORDER: Matching patterns to order disk scanning ORACLEASM_SCANORDER="dm" # ORACLEASM_SCANEXCLUDE: Matching patterns to exclude disks from scan ORACLEASM_SCANEXCLUDE="sd" • When PowerPath multipathing is used on the Linux host, edit these lines as follows: # ORACLEASM_SCANORDER: Matching patterns to order disk scanning ORACLEASM_SCANORDER="emcpower" # ORACLEASM_SCANEXCLUDE: Matching patterns to exclude disks from scan ORACLEASM_SCANEXCLUDE="sd" 2. Shutdown the Oracle instance running on the specific host. 3. Execute the following two commands to restart Oracle ASM: /etc/init.d/oracleasm stop /etc/init.d/oracleasm start Post-Configuration Steps - Using the PowerStore Cluster After the host configuration is completed, you can access the PowerStore cluster from the host. For details on creating, presenting and managing volumes accessed from the host via either the GUI or the CLI, refer to the PowerStore User Guide that matches the version running on your PowerStore cluster. Presenting PowerStore Cluster Volumes to the Linux Host Specify Linux as the operating system when presenting PowerStore cluster volumes to the Linux host. • When adding host groups and hosts to allow Linux hosts to access PowerStore cluster volumes, specify Linux as the operating system for the newly created hosts. • Setting the operating system of the host is required for optimal interoperability and stability of the host with PowerStore cluster storage. You can adjust the setting while the host is online and connected to the PowerStore cluster with no I/O impact. NOTE: Refer to the PowerStore User Guide that matches the version running on your PowerStore cluster for details. 34 Host Configuration for Linux

Configuring Oracle ASM
For proper functioning with Linux hosts using Oracle ASM with PowerStore, configure the Oracle ASM settings file.
Prerequisites
For a PowerStore cluster to function properly with Linux hosts that are using the Oracle ASM volume management software, follow these
steps to configure the
/etc/sysconfig/oracleasm
settings file:
Steps
1.
Modify the following lines in the
/etc/sysconfig/oracleasm
file according to the multipathing used on the host:
# ORACLEASM_SCANORDER: Matching patterns to order disk scanning
ORACLEASM_SCANORDER=""
# ORACLEASM_SCANEXCLUDE: Matching patterns to exclude disks from scan
ORACLEASM_SCANEXCLUDE=""
•
When DM-MPIO multipathing is used on the Linux host, edit these lines as follows:
# ORACLEASM_SCANORDER: Matching patterns to order disk scanning
ORACLEASM_SCANORDER="dm"
# ORACLEASM_SCANEXCLUDE: Matching patterns to exclude disks from scan
ORACLEASM_SCANEXCLUDE="sd"
•
When PowerPath multipathing is used on the Linux host, edit these lines as follows:
# ORACLEASM_SCANORDER: Matching patterns to order disk scanning
ORACLEASM_SCANORDER="emcpower"
# ORACLEASM_SCANEXCLUDE: Matching patterns to exclude disks from scan
ORACLEASM_SCANEXCLUDE="sd"
2.
Shutdown the Oracle instance running on the specific host.
3.
Execute the following two commands to restart Oracle ASM:
/etc/init.d/oracleasm stop
/etc/init.d/oracleasm start
Post-Configuration Steps - Using the PowerStore
Cluster
After the host configuration is completed, you can access the PowerStore cluster from the host.
For details on creating, presenting and managing volumes accessed from the host via either the GUI or the CLI, refer to the
PowerStore
User Guide
that matches the version running on your PowerStore cluster.
Presenting PowerStore Cluster Volumes to the Linux Host
Specify Linux as the operating system when presenting PowerStore cluster volumes to the Linux host.
•
When adding host groups and hosts to allow Linux hosts to access PowerStore cluster volumes, specify
Linux
as the operating
system for the newly created hosts.
•
Setting the operating system of the host is required for optimal interoperability and stability of the host with PowerStore cluster
storage. You can adjust the setting while the host is online and connected to the PowerStore cluster with no I/O impact.
NOTE:
Refer to the
PowerStore User Guide
that matches the version running on your PowerStore cluster for details.
