Additional Information About CLARiiON Storage Systems

The EMC Navisphere® CLI is required to communicate with the CLARiiON storage system. The CLARiiON storage system must be configured to recognized the management server as a privileged user. For more information, see ”EMC Navisphere CLI Is Required” on page 564.

Additional Information About HP EVA Arrays

•To determine provisioning support for HP StorageWorks Arrays, see Table 135 on page 536 and Table 136 on page 537.

•EVA arrays can only be provisioned if they are actively managed by the Command View server that they are discovered through.

When an EVA is discovered by the built-in EVA provider, a cache is created and populated with the current array configuration. Each subsequent cache refresh will start 30 minutes after completion of the previous cache refresh. The time the cache refresh takes depends on factors such as the EVA configuration, model, and SAN traffic.

When you perform a provisioning operation, for example, create, delete, or modify a pool, or volume, the cache information about provisioning is immediately updated. If you provision an EVA using Command View EVA or a different management station, the cached information about the EVA will not be accurate until the cache is refreshed.

Additional Information About IBM DS and ESS

IBM and other storage systems that use external providers show raw capacity for a storage pool, instead of formatted capacity.

1The “Create Volume Using Settings” column refers to the provisioning capability on the management server that lets you create different kinds of volumes from a pool depending on whether you want it optimized, such as for streaming, random access or high availability.

Additional Information About IBM DSS and IBM ESS

Volume groups are not represented in the provisioning or properties of IBM storage systems. The host security groups are based on a host connection, which does not give any indication as to which volume groups each of them belongs. A Volume group can have many host connections, but only one host connection can be part of a volume group.

If there is a failure in a Wizard Provisioning operation on the IBM ESS F20 array, the failure is not reported to the management server from the IBM ESS management software. The Wizard Provisioning UI hangs, appears busy, and becomes unresponsive.

Additional Information About Xiotech

During a provisioning operating on Xiotech, the Provisioning Manager interface remains busy and eventually times out. You can close the provisioning page after a few minutes and check on the array, which should be updated properly.
