Adding Expansion Enclosures

Adding Expansion Enclosures
You can add new expansion enclosures to an existing storage array without turning off
the array or interrupting data flow. “RAID and Expansion Enclosure Cabling Tips” in
Chapter 5 provides additional information on connecting multiple enclosures together
into a larger RAID array.
Caution: You can add only new expansion enclosures to the storage array. This means
that there must be no existing information on the drives in the expansion enclosure you
want to install. If the enclosure you want to install currently contains volumes or
configured hot spare drives, you must delete them before adding the enclosure to a new
configuration.
You may need to refer to the installation manual accompanying your controller and
expansion enclosures to complete this procedure. Add the additional enclosure in a
location within the cabinet that keeps the drive enclosures evenly distributed around the
controller enclosure or storage system. In addition, you want to keep the majority of the
weight in the bottom half of the rack. This procedure may be accomplished by your
service provider or by trained in-house technicians.
To install one or more new expansion enclosures into an existing loop, follow these steps:
1. Follow the instructions in the RAID installation documentation as applicable to set
up and mount the new expansion enclosure(s) and to connect them.
2. Using the information in “Connecting the Drive Loop Cables” on page 65, connect
the cables from the controller enclosure to the new expansion enclosure(s). Then, if
applicable, connect the cables from the existing drive expansion enclosure(s) to the
new expansion enclosure(s). Figure 4-9 shows an example of an expansion
enclosure connected to the RAID controller enclosure.
Warning: Electrostatic discharge can damage sensitive components. Use a
grounded wrist strap or other antistatic precautions before handling enclosure
components.
3. After you have connected the cables to the new expansion enclosure, the controllers
will locate the new disk drives.
