Oracle 2500, 2500-M2, and 6000 Storage Arrays provide a feature called dynamic LUN expansion. This feature allows you to grow your existing volume on the fly without affecting existing data or I/O.
Dynamic LUN expansion increases the capacity of the physical storage. You must then make Solaris aware that the device has grown, and if a file system resides on the device, it must also be grown. If the device is being used as a raw device, for example for a database, please refer to documentation for the application on how to take advantage of the increased capacity.
This document guides you through dynamic LUN expansion and the steps in Solaris to increase the size of the device and file system for three common scenarios:
- simple Solaris disk device (LUN) with a UFS file system
- zpool with ZFS file system
- Solaris Volume Manager metadevice with UFS file system
