Attention

Before you power-on the storage subsystem, it must contain at least four drives. If at least four drives are not installed in each attached storage expansion enclosure and in the DS3200 storage subsystem, when you power-on the DS3200 and its attached storage expansion enclosures, your standard storage partition key might be lost and you must regenerate it, using instructions at http://www.ibm.com/storage/fasttkeys/.

In addition, the resulting insufficient load to the enclosure power supplies might cause them to intermittently appear to have failed, falsely indicating that the power supplies are bad. All drives in the DS3200 storage subsystem and the connected storage expansion enclosure or enclosures must contain no prior configuration data.

vDrive labels: A label is provided on the front of each hard disk drive. Use this label to record the location information for each drive before you remove it. Be sure to keep a record of the drives and their corresponding bays. Also, record the location information in Table 9 on page 110. If you install a drive in the wrong bay, you might lose data.

vDrive LEDs: Each drive tray has two associated LEDs, a green activity LED and an amber status LED. These LEDs indicate the status for that drive.

Figure 45. Hard disk drive LEDs

Activity LED (green)

When this LED flashes, it indicates that there is activity to the drive.

Status LED (amber)

When this LED flashes, it indicates that the drive has been identified by the software. When this LED is lit and not flashing, it indicates that the drive has failed.

vHot-swap hardware: The DS3200 contains hardware that enables you to replace a failed hard disk drive without turning off the storage subsystem. You can continue to operate the DS3200 while a hard disk drive is being removed or installed. These drives are known as hot-swap hard disk drives.
