Host related resources

Related resources are resources that are external to a host, but are related to it through assigned storage, a network connection, or virtual hosting. Related resources that you can view include storage systems and hosts.

Block storage systems

To view information about the storage systems that are related to the hosts, click Block storage systems in the Related Resources section. The number next to Block storage Systems shows the number of storage systems that provide storage to the host.

The storage system is shown as a related resource to the host when the following conditions are met:
  • The host is assigned storage from a storage system. For example, a volume from the storage system is assigned to a file system on the host.
  • The assigned storage from the storage system is visible to the host.
  • The host is a member of an IBM Storage Insights Pro cluster.
Internal resources of block storage systems
You can also view detailed information about the internal resources of related block storage systems. An entry for an internal resource is listed under Block storage Systems when the following conditions are met:
  • The storage system that contains the internal resource is monitored. If a storage system is not being monitored, information about its internal resources is not available.
  • The internal resource is directly associated with the storage that is assigned to the host. For example, if a storage system contains 20 volumes, but only 2 of those volumes are assigned to the host, only those 2 volumes are shown as a related resource.
The type of storage system determines which of the following internal resources are shown:
Volumes
Shows information about the volumes that are assigned to the host. The number next to Volumes shows the number of assigned volumes.
Learn more: Go to Volumes.
Pools
Shows information about the pools that contain volumes that are assigned to the host. The number next to Pools shows the number of pools that contain assigned volumes.
Learn more: Go to Pools, aggregates, and common provisioning groups.
Managed Disks
Shows information about the managed disks that are associated with the volumes that are assigned to the host. The number next to Managed Disks shows the number of disks that are associated with the assigned volumes.
Learn more: Go to Managed disks, external volumes, and array LUNs.
I/O Groups
Shows information about the I/O groups that are associated with the volumes that are assigned to the host. The number next to I/O Groups shows the number of I/O groups that are associated with the assigned volumes.
Learn more: Go to I/O groups.
Nodes
Shows information about the nodes that are associated with the volumes that are assigned to the host. The number next to Nodes shows the number of nodes in the I/O Groups that are associated with the assigned volumes.
Learn more: Go to Nodes, modules, and directors.
Modules
Shows information about the modules that are associated with the volumes that are assigned to the host.
The number next to Modules shows the number of modules in the storage systems that are associated with the assigned volumes.
Learn more: Go to Nodes, modules, and directors.
FC Ports
Shows information about the Fibre Channel storage system ports that are accessible to the volumes that are assigned to the host. The number next to FC Ports shows the number of Fibre Channel ports that are accessible to the assigned volumes. This number represents only the Fibre Channel ports that are associated with the I/O Groups of the assigned volumes. You can use this information to determine if there is an imbalance of the Fibre Channel ports through which volumes are transferring data.
Learn more: Go to FC ports.
IP Ports
The IP ports that the host is dependent on are determined by the IO Groups that host the volumes that are assigned to the host.
Learn more: Go to IP ports.

Fabrics

To view information about the fabrics that are related to the hosts, click Fabrics in the Related Resources section. The number next to Fabrics shows the number of fabrics that are connected to the host.

Internal resources of fabrics
You can also view detailed information about the internal resources of related fabrics. An entry for an internal resource is listed under Fabrics when the following conditions are met:
  • The fabric that contains the internal resource is monitored. If a fabric is not being monitored, information about its internal resources is not available.
  • The internal resource is directly associated with the fabric that is connected to the host. For example, if a fabric contains 20 switches, but only 2 of those switches are connected to the host, only those 2 switches are shown as a related resource.
The type of fabric determines which of the following internal resources are shown:
Ports
Shows information about the switch ports that are connected to the host. The number next to Ports shows the number of port connections that are associated with the host.
Learn more: Go to Ports.
Switches
Shows information about the switches that are connected to the host. The number next to Switches shows the number of switches connected to the host.
Learn more: Go to Switches.
Chassis
Shows information about the chassis that are connected to the host. The number next to Chassis shows the number of Chassis connected to the host.
Learn more: Go to Chassis.
