Expanding The Capacity Of An Array - Compaq 219700-001 - ProLiant - 1500 Reference Manual

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.
