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.
