Limitations on mapping an external volume

You must set the port attribute to External port before you can map the external volume as an internal volume. Make sure to check the capacity requirements of the external volume you intend to map as an internal volume.

Following are the limitations on mapping an external volume:

• You cannot access data that is stored in an area that exceeds the maximum capacity of the external volume. For example, if you map 100 GB of an external volume as 70 GB of the internal volume, 30 GB of the external volume cannot be accessed from the local storage system side.

• You cannot map an external volume which does not meet the minimum capacity requirement. For example, you cannot map 10 GB of the external volume as an internal volume with a minimum capacity requirement of 30 GB.

• Volumes for which the T10 PI attribute is enabled cannot be specified as an external volume.
