Adding Capacity to the Disk Array As your system storage requirements grow, you may need to increase the capacity of your disk array. Disk array capacity can be increased in any of the following ways: • You can add new disk modules to the disk array if there are empty slots in the disk enclosures. • You can add additional disk enclosures to the disk array. • You can replace existing disk modules with higher capacity modules. Adding More Disk Modules If there are empty slots in the disk enclosures, the easiest way to increase capacity is to add more disk modules and create additional volume groups. You can also add a disk to increase the capacity of an existing volume group. The disks you add will typically be used to create volume groups, so make sure you add enough disk modules to create the desired structure. Disk modules can be added to the disk array while it is online without disrupting operation. CAUTION Ensure that there is no important data on the disk module you are installing in the disk array. Any data on the disk will be lost when it is installed. To increase capacity by adding disk modules: 1. Install the disk modules in available slots in the disk enclosures. See "Disk Enclosure Modules" on page 291 for instructions on installing disk modules. Note Each disk in the volume group must be in a different enclosure/channel to maintain high availability. 2. Create a volume group or add the disk to an existing volume group. 200 Adding Capacity to the Disk Array
