For the detail on how to build the cluster application, refer to "Chapter 6 Building Cluster Applications" in "PRIMECLUSTER Installation and Administration Guide."
Set the mirroring among the servers of GDS (creating netmirror volume) in this setting.
It is not necessary to set "6.2 Initial GLS Setup" in "PRIMECLUSTER Installation and Administration Guide" because it has been already set in "3.6.1 Initial GLS Setup" above.
Note
Change and set the values of the following tuning parameters configured with "Setting Tuning Parameters" in setting procedures of the iSCSI device for GDS ("Disk Setting for Performing Mirroring among Servers" in "PRIMECLUSTER Global Disk Services Configuration and Administration Guide").
Tuning parameter name | Value after change |
|---|---|
ED_CMD_RETRY_COUNT | 100 |
ED_DRV_RETRY_COUNT | 100 |
Example:
ED_CMD_RETRY_COUNT=100 ED_DRV_RETRY_COUNT=100
To extend the timeout period (CLUSTER_TIMEOUT) of the CF heartbeat, change the above parameter values according to the following formula. Round up the values after the decimal point.
Calculation formula:
<Increased CLUSTER_TIMEOUT> / 3 + 100
Also, specify the IP address of the public LAN (used also for the administrative LAN) as the IP address for the mirroring among servers used in "Creating iSCSI Target," and "Establishing iSCSI Session" of the above manual.
If the icmp communication between cluster nodes is not allowed in the security group configuration, the following message is displayed when the clchkcluster command is executed.
Admin IP <IP address> used by SF is not alive.If this message is output, refer to "3.1.2.3 Creating the Security Group for the Public LAN (Used also for the Administrative LAN)", and set the icmp protocol rule to allow the icmp communication between cluster nodes. After that, execute the clchkcluster command again.
When using the Symfoware Server (Native) Hot Standby feature, the standby and scalable userApplication configurations are required.
Set the standby userApplication attribute to the following value.
Attribute | Setup value |
StandbyTransitions | ClearFaultRequest | SwitchRequest |
Refer to "6) Scalable operation" in "6.7 Setting Up Cluster Applications" in the "PRIMECLUSTER Installation and Administration Guide" for detailed build instructions.
