Basic administration tasks

Basic administration tasks include creating storage pools, and creating and administering volumes. This includes performing tasks such as adding or removing mirrors or columns from volumes, resizing volumes, and creating and using volume snapshots.

The system administrator's role requires the following knowledge of ISP:

• Familiarity with the meaning of the terms disk group, storage pool, template, user template, application volume, and capabilities such as reliability, performance and fault tolerance.
• What templates and user templates are available for use in creating volumes with the required capabilities.
• What templates and user templates are associated with the disk groups in which you will create volumes.
• How to use the VEA or the vxassist and vxvoladm commands to perform your tasks.

As a system administrator, you can use either the VEA or the vxassist and vxvoladm utilities to perform your tasks. The VEA graphical interface is most suitable for day-to-day administration. The vxassist and vxvoladm utilities are primarily intended for use in administration scripts.

Figure 1-3 shows the use of the vxassist or vxvoladm command to create application volumes.
