Adding Capacity To The Disk Array; Adding More Disk Modules - HP Surestore Disk Array 12h - And FC60 Service Manual

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.
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
Modules" on page 291
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.
