Adding an SSP cluster by using the All Shared Storage Pool Clusters menu

With HMC version 8.40 or later, if you are using an HMC Enhanced+ interface, you can add Shared Storage Pool (SSP) clusters by using the All Shared Storage Pool Clusters menu in the Hardware Management Console (HMC).

To add shared storage pool clusters to a Virtual I/O Server (VIOS), by using the HMC, complete the following steps:

1. In the navigation pane, click the Resources icon .
2. Click All Shared Storage Pool Clusters. The All Shared Storage Pool Clusters table is displayed. The table lists all clusters that can be accessed by the HMC (all servers managed by the HMC).
3. Click Add Shared Storage Pool Cluster. The Add Shared Storage Pool Cluster Wizard opens.
4. Click General Settings tab.
   1. Enter a cluster name in the Cluster Name field.
   2. Enter a shared storage pool name in the Shared Storage Pool field.
   3. Under Tier Capability, select Single tier capable or Multiple tier capable to specify if you want the cluster to be single-tier or multitier capable. Multiple tier support provides a selection of resources, including Virtual I/O Servers that provide this feature. You can create the cluster and the system tier by using this wizard.
   4. Enter a tier name in the System Tier Name field.
   5. Enter the freespace threshold percentage in the Freespace Threshold % field.
   6. Enter the overcommit threshold percentage in the Overcommit Threshold % field.
5. Click Next or click the Nodes tab.
   1. Select a node from the Virtual I/O Server Cluster Nodes table.
6. Click Next or click the Repository Disk tab.
   1. Select a disk from the Cluster Repository Disks table.
7. Click Next or click the System Tier tab.
   1. Select a physical volume from the Physical Volumes table.
   2. Select Mirroring and enter the names of the Failure group 1 and Failure group 2. Mirroring enables you to assign physical volumes to the failure group 1 and failure group 2 that are contained by the tiers. The same data is replicated in both the failure groups. If you enable mirroring you can retrieve data when the data is lost from one failure group. To enable mirroring, you must assign the physical volumes in the table to the failure groups.
      Note: The system tier that is created in this wizard is unrestricted and it is the default tier.
8. Click Next or click the Summary tab. Verify that the shared storage pool cluster is added and complete one of the following steps:
   • Click Back to change the parameters.
   • Click Finish to add the shared storage pool cluster.
