Settings for Using Oracle RAC 10g or Oracle RAC 11g

Settings for MISSCOUNT and DISKTIMEOUT

When a host and an Oracle RAC voting disk are connected by multiple paths,
HDLM performs failover processing for those paths (in the same way as for
normal paths) when an I/O timeout occurs for one of the paths.
Note that, depending on the settings of Oracle RAC, Oracle RAC might
determine that a node error has occurred before the failover processing
performed by HDLM is completed, and then re-configure the cluster.
Therefore, when HDLM manages the paths that are connected to an Oracle
RAC voting disk, change the following settings according to your version of
Oracle RAC:
When using Oracle RAC 10g 10.1.0.3.0 or later or Oracle RAC 11g:
Change the value of MISSCOUNT to match the type of storage system. To
do so, use the following table to obtain the value to be specified, and then
change the current value to a value equal to or greater than the value
you have obtained.
