The purpose of listing unmanaged storage arrays is that Oracle VM warns you when it detects storage in the environment for which no particular management mechanism is available or in case the appropriate management mechanism cannot be determined. In other words, the unmanaged storage arrays, for iSCSI and for fibre channel, are placeholders for physical disks of which the appropriate location in the storage management tree is unclear.

It should be noted that the unmanaged arrays behave differently for iSCSI and fibre channel. For iSCSI the use of the unmanaged array in practice is temporary, but for fibre channel the situation is different. Because generic fibre channel arrays are simply detected when they are connected to the storage network, there is no mechanism to place them under a separate storage array based on a specific access host. Consequently, generic fibre channel LUNs will remain in the unmanaged fibre channel storage array, which has no access group.

You may choose to delete the unmanaged storage elements from the Oracle VM environment in case you do not intend to use it. In the case of generic iSCSI storage arrays, it is preferable to register them in the correct way by following the procedures in Section 4.6.3, “Registering and Configuring Storage Arrays”. To properly register the storage entries, you should remove them from the unmanaged array. After registration these entries are displayed under a managed storage array of the appropriate type.

Vendor-specific storage, which does not use a generic Storage Connect plug-in, must always be registered with its dedicated plug-in and appears under its own storage array entry in the storage management tree.
