Hitachi Dynamic Link Manager Software Users Guide for Linux

• For ASMLib 2.1.0 or later:
# /usr/sbin/oracleasm configure
• For ASMLib versions earlier than 2.1.0:
# /etc/init.d/oracleasm configure
b. Open the ASMLib configuration file (/etc/sysconfig/oracleasm).
c. Change the ORACLEASM_SCANORDER line as follows:
ORACLEASM_SCANORDER ="sddlm"
If an ASM disk defined in an HDLM device already exists, perform this
procedure, and then restart all the nodes.
This step must be done to enable the settings.
• Depending on the version of Red Hat Enterprise Linux, the following
differences might apply:
¢
If you use HDLM with Oracle RAC 11g Release 2 in Red Hat Enterprise
Linux 6.0, 6.1, or 6.2, you can use shared file systems created by
using ADVM (ASM Dynamic Volume Manager) or ACFS (ASM Cluster
File System) for the archived REDO log file area. However, note that
PSU 11.2.0.3.3 or later is required.
¢
If you use HDLM with Oracle RAC 11g Release 2 in a version of Red
Hat Enterprise Linux that is not 6.0, 6.1, or 6.2, you cannot use
shared file systems created by using ADVM or ACFS for the archived
REDO log file area.
If you use Oracle RAC 11g Release 2 and HDLM together in Red Hat
Enterprise Linux 6, you can use the shared file systems created by
using ADVM and ACFS as the archived REDO log area. However, if you
use Oracle RAC 11g Release 2 (11.2.0.3.0) and HDLM together in Red
Hat Enterprise Linux 6.0, 6.1, or 6.2, then PSU 11.2.0.3.3 or a later
version is required.
Settings for the RHCM
The user must execute the following procedure when HDLM is installed in an
environment that uses RHCM.
Note:
For Oracle Unbreakable Enterprise Kernel 5, RHCM environments are not
supported.
Notes on Using RHCM
The HDLM device used by the cluster service and the HDLM device used by
Quorum must be the same.
When Using Red Hat Enterprise Linux AS4/ES4
To specify settings for RHCM:
1. Stop the service of the RHCM cluster.
