2-3 s some operating systems limit number of logical drives or drive controllers The maximum number of controllers and drives supported depends on several factors. To determine the number of drives supported by your server, refer to the Setup and Installation Guide, or Reference Guide, that accompanied your server. Server specifications are also available at our website, www.compaq.com. Expanding the Capacity of an Array Below is an overview of procedures for expanding the capacity of an array. 1. Review. See Appendix D, "Adding Storage Capacity," for information on expanding the storage capacity of an existing SMART-2DH array. 2. Back up data. Although data loss is not anticipated during a normal capacity expansion, it is a good idea to back up all data in the array you will be expanding. This backup may also be used to return to the original configuration, if necessary. 3. Add drives. If you are using a server or storage system that does not support hot-pluggable drives, you will need to power down the server or storage system to add new drives. If you are using a server or storage system that does support hot-pluggable drives, do not power down the system or take it offline. Simply plug the new drives into vacant bays. 4. Configure drive array. See "Capacity Expansion" in Chapter 5 for instructions on using the Compaq Array Configuration Utility to reconfigure your drive array to make use of the added capacity. If your operating system supports it, run the Array Configuration Utility online to guide you through the process. The controller automatically redistributes the data.
