The system requirements for provisioning include basic hardware and licensing requirements as well as additional requirements for shared memory and cache management devices.
The storage system hardware and
firmware must be configured and ready for use.
The parity groups in the storage system must be configured and ready for use.
Device Manager - Storage Navigator must be configured and ready for use. For details and instructions, see the
System Administrator Guide for your storage system.
The license keys for the provisioning software products must be enabled. For details and instructions, see the
System Administrator Guide for your storage system.
The required amount of shared memory for your operational environment must be installed in the storage system.
The required number of cache management devices must be available.
The desired system option modes (SOMs) must be enabled on your storage system before you begin operations. For information about SOMs,
contact customer support.
Cache management devices are used to manage the cache associated with volumes (LDEVs). Each volume (LDEV) requires at least one cache management device. An LDEV that is not a DP-VOL requires one cache management device. For an LDEV that is a DP-VOL, you need to calculate the number of cache management devices required.
There are several provisioning strategies that you can implement on your storage system to solve business requirements. Provisioning your storage system requires balancing the costs of the solution with the benefits that the solution provides.
Cache management devices are used to manage the cache associated with volumes (LDEVs). Each volume (LDEV) requires at least one cache management device. An LDEV that is not a DP-VOL requires one cache management device. For an LDEV that is a DP-VOL, you need to calculate the number of cache management devices required.
When you log on to
Device Manager - Storage Navigator, your user access privileges determine the resources you can view and the operations you can perform. User access privileges are determined by the user groups to which the user belongs and the resources assigned to those user groups. To perform an operation on the storage system, you must have access to the resources (for example, volumes, pools, ports) that are required for the operation.
