33.1 Get Started with Managing Storage

Oracle Enterprise Manager discovers and manages storage resources and their components, including storage pools, storage hardware, filesystems, and logical volumes.

A storage server exposes its resources as Logical Units (LUNs) or Shares. A storage client has access to these LUNs and shares, and represents them as its own filesystems or devices and also exposes these filesystems to its own clients, such as applications, databases, or virtual machines.

The System Infrastructure plug-in manages the storage resources for a Storage Appliance and for a Host.

Storage management includes all the activities for making storage resources available to operating systems and virtual assets. The following are some of the activities:

• Discover storage targets and derive their relationship.

• Collect configuration and performance metrics for all storage target components.

• Detect incidents.

• Monitor the storage target components such as, LUNs, filesystems, projects, and pools.

33.2 Location of Storage Information in the User Interface

Table 33-1 shows where to find information.

33.12 About Storage Cluster Membership

You can have a cluster configuration setup with two Oracle ZFS Storage Appliances. When such configuration is in use, you can view the cluster membership information of the two appliances.

33.12.1 Viewing Storage Cluster Membership

To view cluster membership information of the appliances which are in a cluster configuration setup, perform the following steps:

1. From the Targets menu, select All Targets.

2. In the left navigation pane, expand Groups, Systems and Services target type.

   You can view a list of cluster targets under Groups, Systems and Services.

3. Click a specific cluster target under Groups, Systems and Services.

   The target name, target type, and the target status of the selected target is displayed in the right pane.

4. Click on a specific cluster target name from the list in the right pane.

5. Click the Target Navigation tab which appears to the left of the cluster drop-down list, as shown in Figure 33-7.

   Description of ''Figure 33-7 Target Navigation Tab View''
   
   

6. Select a specific cluster to view the storage summary details of the cluster. You can view the cluster information in the dashboard, images of the storage appliance which have a cluster configuration setup, different networks and pools information.

33.13 About Storage Resource Deletion

When an appliance or a host is discovered as a target, it automatically promotes some of the target members. See Target Members of an Oracle ZFS Storage Appliance to view the list of automatically promoted target members. You can choose to either remove the target or remove its members. If you choose to remove a target, such as an appliance or a host, all the associated members are also removed. See Removing a Storage Resource for the steps to remove a storage resource.

You must start the deletion process from the target level to delete all the members.

Note:

If the target members have a proper association with an appliance or a host, the deletion of these members is successful. For example, a diskshelf target member is associated to a ZFS Storage Server. If the association of these target members are not correct, diskshelf target members are not deleted.

33.13.1 Removing a Storage Resource

To remove a storage resource, perform the following steps:

1. From the Targets menu, select All Targets.

2. In the left navigation pane, expand Servers, Storage and Network target type.

   You can view a list of appliance targets under Servers, Storage and Network.

   Note:

   To view the cluster targets, expand Groups, Systems and Services in the left navigation pane. Select a specific cluster target in the right pane.

3. Click a specific appliance target under Servers, Storage and Network.

   The target name, target type, and the target status of the selected target is displayed in the right pane.

4. You can proceed to delete a storage resource by following one of these methods:

   • Right-click on the target name which you want to remove in the right pane.

   • Click a specific target name in the right pane, and then click the target drop-down list which appears to the top-left of the user interface.

5. Select Target Setup and click Remove Target.

6. In the confirmation dialog box, click Yes to remove the specific target.

33.13.2 Removing an Oracle ZFS Storage Appliance Cluster

You can delete an Oracle ZFS Storage Appliance which is part of a cluster. See Removing a Storage Resource for steps to delete an Oracle ZFS Storage Appliance. When two Oracle ZFS Storage Servers have a cluster configuration setup, the deletion of cluster target initiates deletion of both the storage servers in the cluster and the associated target members, such as, diskshelves. The members of an Oracle ZFS Storage Appliance include the following:

• ZFS Storage Server

• Diskshelf

• ZFS Storage Appliance Cluster

When you initiate deletion of one of the storage server that is a part of the cluster configuration setup, the associated cluster target is deleted. The other storage server is not deleted. The diskshelves are not deleted if there is a second storage server.

When you initiate deletion of a storage server that is not a part of the cluster configuration setup, the associated diskshelves are deleted.

33.14 Using Oracle ZFS Storage Appliance in Engineered Systems

This section describes the prerequisite for an Oracle ZFS Storage Appliance on engineered systems. A non-root user should have required privileges to view the analytic datasets. If the specific privileges are not assigned, then the analytic metrics displays an error. You can add an extra privilege to a non-root user to access datasets.

To add a privilege in the appliance's user interface, perform the following steps:

1. Login to Oracle ZFS Storage Appliance user interface.

2. Click Configuration.

3. Click USERS.

4. Select non-root user and click edit icon.

5. Click Exceptions.

6. In the Scope drop-down, select Analytics.

7. Select the read: Read a statistic with this drilldown present check box.

8. Click ADD.

You can also add an exception to a non-root user using Command Line Interface for reading analytics dataset. For example:

zfssa:> configuration users
zfssa:configuration users> select oemuser
zfssa:configuration users oemuser> exceptions
zfssa:configuration users oemuser exceptions> create
zfssa:configuration users oemuser auth (uncommitted)> set scope=stat
                         scope = stat
zfssa:configuration users oemuser auth (uncommitted)> set allow_read=true
                    allow_read = true (uncommitted)
zfssa:configuration users oemuser auth (uncommitted)> commit
zfssa:configuration users oemuser exceptions>
