7.3.3 Maintaining the environment of an SSO cluster system (in Linux)
This subsection describes how to maintain the active and standby nodes in a Linux SSO cluster system environment.
- Organization of this subsection
(1) Maintenance on the active node
The procedure for maintenance on the active node consists of the following steps:
-
Pre-maintenance setup
-
SSO maintenance
-
Setup of the action definition file
-
Post-maintenance setup
Each step of the above procedure is described below.
(a) Pre-maintenance setup
Execute the cluster environment setting command (ssoclustersetup) to perform pre-maintenance setup for the SSO cluster environment on the active node. For details about the cluster environment setting command, see ssoclustersetup (Linux only) in 5. Commands.
For the arguments of the cluster environment setting command, specify values as shown in the following table:
|
Argument |
Value to be specified |
|---|---|
|
First argument |
-beforemaint (specifies that pre-maintenance setup is to be performed) |
|
Second argument |
-primary (specifies that the active node is the target) |
|
Third argument |
Shared folder name on the shared disk Example: K:\shared\SSO |
The following shows an example of the command that performs pre-maintenance setup:
ssoclustersetup -beforemaint -primary /shared/sso
If an error occurs, correct it with reference to the message that appears. After you have corrected the error, re-execute the command.
(b) SSO maintenance
Perform overwrite installation or upgrade-installation of SSO. Alternatively, apply patches to SSO.
(c) Setup of the action definition file
Set up the action definition file according to the need.
- To monitor a new IPv6 network:
-
Use the cluster environment setting command (ssoclustersetup) to set an IPv6 logical IP address.
For the arguments of the cluster environment setting command, specify values as shown in the following table:
Argument
Value to be specified
First argument
-defset (specifies that the action definition file is to be set)
Second argument
Logical IP address (IPv6 address)
The following shows an example of the command that sets an IPv6 logical IP address:
ssoclustersetup -defset 2001:db8::7c
If an error occurs, correct it with reference to the message that appears. After you have corrected the error, re-execute the command.
(d) Post-maintenance setup
Execute the cluster environment setting command (ssoclustersetup) to perform post-maintenance setup for the SSO cluster environment on the active node. For details about the cluster environment setting command, see ssoclustersetup (Linux only) in 5. Commands.
For the arguments of the cluster environment setting command, specify values as shown in the following table:
|
Argument |
Value to be specified |
|---|---|
|
First argument |
-aftermaint (specifies that post-maintenance setup is to be performed) |
|
Second argument |
-primary (specifies that the active node is the target) |
|
Third argument |
Shared folder name on the shared disk Example: /shared/sso |
The following shows an example of the command that performs post-maintenance setup:
ssoclustersetup -aftermaint -primary /shared/sso
If an error occurs, correct it with reference to the message that appears. After you have corrected the error, re-execute the command.
(2) Maintenance on the standby node
The procedure for maintenance on the standby node consists of the following steps:
-
Pre-maintenance setup
-
SSO maintenance
-
Post-maintenance setup
Each step of the above procedure is described below.
(a) Pre-maintenance setup
Execute the cluster environment setting command (ssoclustersetup) to perform pre-maintenance setup for the SSO cluster environment on the standby node. For details about the cluster environment setting command, see ssoclustersetup (Linux only) in 5. Commands.
For the arguments of the cluster environment setting command, specify values as shown in the following table:
|
Argument |
Value to be specified |
|---|---|
|
First argument |
-beforemaint (specifies that pre-maintenance setup is to be performed) |
|
Second argument |
-secondary (specifies that the standby node is the target) |
|
Third argument |
Shared folder name on the shared disk Example: /shared/sso |
The following shows an example of the command that performs pre-maintenance setup:
ssoclustersetup -beforemaint -secondary /shared/sso
If an error occurs, correct it with reference to the message that appears. After you have corrected the error, re-execute the command.
(b) SSO maintenance
Perform overwrite installation or upgrade-installation of SSO. Alternatively, apply patches to SSO.
(c) Post-maintenance setup
Execute the cluster environment setting command (ssoclustersetup) to perform post-maintenance setup for the SSO cluster environment on the standby node. For details about the cluster environment setting command, see ssoclustersetup (Linux only) in 5. Commands.
For the arguments of the cluster environment setting command, specify values as shown in the following table:
|
Argument |
Value to be specified |
|---|---|
|
First argument |
-aftermaint (specifies that post-maintenance setup is to be performed) |
|
Second argument |
-secondary (specifies that the standby node is the target) |
|
Third argument |
Shared folder name on the shared disk Example: /shared/sso |
The following shows an example of the command that performs post-maintenance setup:
ssoclustersetup -aftermaint -secondary /shared/sso
If an error occurs, correct it with reference to the message that appears. After you have corrected the error, re-execute the command.
