Primary Storage

In IBM Spectrum Control Storage Insights, a #cloud offering, you can organize resources 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.

So you want to monitor all the ports on your SAN Volume Controller (SVC) but also want to separately monitor the following subsets of ports on the SAN Volume Controller:

• Ports that are used for inter-node communication
  
• Ports that are used for host I/O exchanges
  

To add the ports to a general group hierarchy, complete the following steps:

1. Add the ports that are used for inter-node communication to a general group, for example, SVC Inter Node Ports.
   
2. Add the ports that are used for host I/O exchanges to another general group, for example, SVC Host I/O Ports.
   
3. Add the groups as subgroups of a parent general group, for example, SVC All Ports.
   

Now you can quickly view information about the resources in the hierarchy on the details page for the general groups.

When you view the SVC Inter Node Ports or SVC Host I/O Ports groups, you see information about the specific ports that are members of that subgroup (subset).

To view subgroups in a general group hierarchy:

1. In the menu bar, click Groups > General Groups.
   
2. Click the number of groups or the group name (for example, SVC Inter Node Ports or SVC Host I/O Ports) that is shown in the subgroups column.
   
3. Click the Subgroups tab.
   

When you view the parent group, for example, SVC All Ports, you see information about the ports that are members of the parent group and also the ports in the subgroups (subsets).

To view the parent group, in the menu bar, click Groups > General Groups.
The following general groups are shown:

• The top-level groups in general group hierarchies
  
• All general groups that are not part of a general group hierarchy
