System Automation for Multiplatforms resource groups

Edit online

Use System Automation for Multiplatforms resources groups with defined automation policies to manage the IBM Storage Protect components for this cluster. The only exception is the database server instance resource that is managed by the IBM Storage Protect server.

The shared file systems and IBM Storage Protect components are defined as resources. Multiple resources make up a resource group. Each resource in a resource group has a resource type. Each IBM Storage Protect instance in a cluster includes one resource group. During planned outages, resource groups can be manually moved from the primary node to the secondary node.

The IBM Storage Protect resource group includes the following resources. The name of the IBM Storage Protect resource group is SA-tsm-inst1-rg, where inst1 is the instance name. The following resources are used for different but mandatory functions in this cluster.

Service IP: The Service IP resource is used for communication. It is called tsm-inst1-ip-rs, where inst1 is the instance name. Service IP is managed by System Automation for Multiplatforms. This IP is available on the node where the IBM Storage Protect server is running. You must create the Service IP logical interface on the same physical interface as the public network interface.

Shared disk storage resource

A shared disk storage resource is a physical storage device on the IBM Storage Protect server where IBM Storage Protect and IBM Db2 application data is stored. You must create the following disk storage resources:

Instance directory - tsm-inst1-instdir-ag
Db2 directory - tsm-inst1-db2dir-ag
Active log directory - tsm-inst1-actlog-ag
Archive log directory - tsm-inst1-archlog-ag

Shared disk storage for storage pools: The storage pool resource includes physical storage devices on the IBM Storage Protect server where client data is stored.

Volume group resources: If you decide to configure your storage by using volume groups, a volume group resource is available for the preceding shared disk storage resources. Volume group resources are automatically created by System Automation for Multiplatforms.

Application resources for the IBM Storage Protect server instance

The IBM Storage Protect server instance resource is the server resource that manages the IBM Storage Protect application. This resource is managed by System Automation for Multiplatforms control scripts.

Table 1. Tasks that are completed by the System Automation for Multiplatforms control scripts
Tasks	Description	Sample commands
Start	Starts the IBM Storage Protect server instance.	The /opt/tivoli/tsm/server/bin/rc.dsmserv -u db2inst1 –i /tsminst1 command starts the server instance with the db2inst1 user in the /tsminst1 directory.
Stop	Stops the IBM Storage Protect server instance.	kill –s SIGURG 345 where `345` is the `PID`. The `PID` can be found in the /tsminst1/dsmserv.v6lock file.
Monitor	Checks whether the /tsminst1/dsmserv.v6lock file exists. It uses the `PID` to check whether the process is running.	ps -ef \| grep 345 where `345` is the `PID`.
