Administering hosts

Administer the hosts that are monitored by IBM Storage Insights Pro.

You can monitor and administer hosts on the following pages in the GUI:
Table 1. Locations where you can administer hosts
Location in GUI Steps

Hosts page
  1. From the Resources menu, click Hosts.
  2. Right-click a host in the list and select an action.

Hosts properties page
  1. From the Resources menu, click Hosts.
  2. Right-click a host in the list and select View Properties.
  3. On the General tab, click Edit to modify the properties.

Overview page for the host
  1. From the Resources menu, click Hosts.
  2. Right-click a host in the list and select an View Details.
  3. Click the Actions button and select an action.
Use the following right-click actions to monitor and administer hosts:
Table 2. Actions for administering hosts
Action Description
View Properties View general and storage capacity information about the host.
View Details View charts that show the space that is assigned to a host from storage systems and performance information, such as the most active storage system volumes. From the Overview page, you can access internal and related resources, and other information about the host.
View Performance View a chart that shows the performance trends for one or more hosts over the previous month. Use this information to monitor the performance of storage systems that is assigned to hosts.

You can change the time range of the chart and the metrics that are shown.
View Capacity View a chart that shows the capacity trends for one or more hosts over the previous month. Use this information to monitor the amount of disk capacity from storage systems that is assigned to hosts and how much of that capacity is being used.

You can change the time range of the chart and the metrics that are shown. The default metrics are Mapped SAN Capacity and Used SAN Capacity.
View Alert Policy and Definitions View, set, or create the alert policy for a host. Use alert policies to manage the alert definitions and notification settings that apply to hosts. The tasks that you can do depend on whether the host is managed by an alert policy.
  • Managed by an alert policy: View the policy or set a different policy to manage the host. Click View Policy or Set Policy from the Policy Actions menu.
  • Not managed by an alert policy: Set a policy to manage the host or create a policy from the existing alert definitions. Click Set Policy or Create Policy from the Policy Actions menu.

    If you don't want to use a policy, you can edit the alert definitions. Click Alerts Definitions in the General section.

Add to Application Add the host to a new or existing application. Use applications to monitor the capacity and performance of the storage resources that your critical applications use in one place. Learn more.
Add to General Group Add the host to a new or existing general group. Organizing hosts into general groups and their subgroups can be helpful when you want to quickly view information about a group of resources, but you also want to view information about subgroups of resources within the group.

Separate Host, Merge Hosts

The Merge Hosts action is available when you select multiple unmonitored hosts.

 IBM Storage Insights Pro creates and updates unmonitored hosts automatically after data is collected for the storage systems. Depending on your storage environment, IBM Storage Insights Pro might not model all of the hosts in your environment correctly. For example, IBM Storage Insights Pro might identify 6 host connections and create an unmonitored host for each host connection. However, in your environment, these 6 host connections are actually on one host. In this case, you need to merge the six unmonitored hosts into one host.

Similarly, IBM Storage Insights Pro might create a host from a group of host connections that appear to be related. In this case, you can separate the hosts from the unmonitored host.
Edit Properties

This action is available when you select multiple hosts.

 Add or change the properties for multiple hosts. You can specify the OS type, location, and custom tag properties.

You can use the properties to filter or sort the hosts in the GUI or in an external application if the data is shared or exported.

When you click Edit Properties, the properties in the notebook can have the following values:
  • If the property is blank, it means that the hosts that were selected have different values assigned to that property. For example, the hosts run on different operating systems or the hosts have different locations.
  • If the selected hosts have the same value for a property, the value is shown.
Note: After separating hosts, any existing alert will only affect the primary host. Similarly, any group membership will only remain for the primary host. The separated hosts need to be reconfigured after the separation action.
