Setting the default storage tier
A default storage tier must be identified within a storage pool. The default tier is created first. You can change the default storage tier by using the Virtual I/O Server (VIOS) command-line interface.
The first user data tier that is created during the creation of the cluster, is the default (or provisioning) tier. This is the default tier, only for the placement of user data for virtual disks if a tier name is not specified. The default tier for user data can be changed, if the chosen default is not suitable.
To set a storage tier as the default storage tier, complete the following steps:
The storage tier with the name tier1 is now set as the default tier. Because you can only have one default tier, the settings for the previous default tier is automatically set todefault=no.
