Installing and Configuring Additional Enclosures

Arrays are preconfigured on the DPS Expansion Module controller enclosure and any DPS

Expansion Module expansion enclosures shipped with it. You must install and configure any

drives and enclosures shipped separately. For every six drives, you can create an array or a

set of hot spares. You can attach up to four DPS Expansion Module expansion enclosures with

up to two arrays each to an DPS Expansion Module controller enclosure.

Adding arrays and enclosures to a DPS1000 Series configuration

Use the following procedures as you add arrays and enclosures to your current DPS1000

Series and DPS Expansion Module configuration.

Note

You must power off all DPS Expansion Module enclosures when you add arrays or

expansion enclosures. When an enclosure is powered off, all virtual tapes saved on its

arrays are unavailable to DPS1000 Series. Therefore, DPS1000 Series should be shut

down from its web interface and power should remain off until the arrays are fully

configured. This prevents users from trying to access inaccessible virtual tapes.

To add a second array to an XDC1200a or XDS1200a-1

1. Shut down DPS1000 Series from its web interface and power off any connected DPS

Expansion Module enclosures.

2. Install the drives. Refer to Installing drive carrier modules on page 18.

3. Create the array. Refer to Creating arrays on page 30.

4. Create the logical drive. Refer to Creating logical drives on page 32.

5. Power on DPS1000 Series.

6. Power on all connected DPS Expansion Module enclosures.

Note

When you connect a new DPS Expansion Module array to DPS1000 Series, DPS1000

Series will quickly start moving data to it to balance all DPS1000 Series storage. As a

result, DPS Expansion Module may be busy soon after it is powered on.

To add a set of hot spares to an XDC1200a or XDS1200a-1

1. Shut down DPS1000 Series from its web interface and power off any connected DPS

Expansion Module enclosures.

2. Install the drives. Refer to Installing drive carrier modules on page 18.

3. Create the hot spares. Refer to Designating hot spares on page 33.
