Adding Capacity to the Disk Array
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 LUNs. The disks you add will typically be used to
bind LUNs, 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.
C
AUTION
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 386
for instructions on installing disk modules.
Note
Each disk in the LUN must be in a different enclosure/channel to maintain high
availability.
