SSA RSM The Logical View Diagnostic Analysis Physical View Contents

The Logical View displays the SSA resources which can be accessed by the selected adapter. The resources are split into two types, arrays and disks.


Array Resources

The Logical View displays a Logical Group header for each of the RAID types supported by the selected adapter. The corresponding array resources are listed under the relevant Logical Group header. This list contains all arrays of that RAID type, no matter what their usage. The resource icon colour indicates the current usage of the resource.

For example, if your adapter supports RAID-1 arrays, and you have created two, one is 'Free' and the other is a 'System (PC)' 1 resource. Both arrays will be listed under the Logical Group, RAID-1.

Each array has a unique identifier, its name, which is assigned during the array creation.

The Logical Group name links to the relevant Resource List, from here you can view existing arrays and create new resources of that RAID type.

Note:

If an array is connected to an adapter which does not support the array type, the array members may be listed under the 'Pre-configured' Logical Group.

Note:

If an array is connected to an adapter which is running in cluster mode, and the adapter does not support the array type when running in cluster mode, the array may be listed with a status of 'offline'. To solve this problem, re-cable the adapter in a non-cluster mode and delete the resource if necessary.


Non-RAID Disk Resources

The term disk is used below, this should be taken to mean Non-RAID Disk.

The Logical View displays a Logical Group header for each disk type that is supported by the selected adapter. The corresponding disk resources are listed under the relevant Logical Group header. This list only contains disks in the given usage group. The resource icon colour indicates the current usage of the resource, which will be the same as the Logical Group.

Each disk has a unique identifier, its serial number.

The Logical Group name links to the relevant Resource List. From here you can view disks in that usage class. Further selection of an individual disk allows you to change the usage of that disk.

Note:

When a disk is supplied from the manufacturing plant, or has been low level formatted via RSM, it will initially be grouped under the 'System (AIX)' usage. To make the disk into a 'Free' disk, select the 'System (AIX)' resource list and delete the disk from this group.

Note:

If a resource is 'Unsupported', it will not be visible in the Logical View. Select the Physical View, then the resource. From the Disk View, select 'Format'. This should return the disk to the 'System (AIX)' usage. If the disk cannot be formatted, contact your service representative for a replacement.


Array and Disk types supported by IBM SSA Adapters

The table below lists the resource types supported by each SSA adapter.

Non-Cluster Mode (1-way): Only one adapter is connected to the SSA resources. Each loop starts and ends on the same adapter, and no other adapters are connected within the loop.
Cluster Mode (2-way): Two adapters are connected to shared SSA resources. That is, the loop starts and ends on the same adapter, but other adapters are connected within the loop.
