2 Maintaining Drives

You can replace a failed drive while the array remains running.

About Drive Types

Depending on your configuration, your array supports up to 24 2.5-inch SAS drives or up to 12 3.5-inch

SAS drives in internal drive bays.

Drives are connected to a backplane through drive carriers and are hot-swappable.

Drives are supplied in a carrier that is keyed to fit into specific array models, and cannot be installed in other

Dell arrays or arrays not from Dell Inc.

Identifying Failed Drives

A drive failure is indicated by:

• LEDs on the drive. See Interpreting Drive LEDs.

• A message on the console, in the event log, or in the Group Manager Alarms panel.

• Indications in the Group Manager Member Disks window or the CLI

member select show disks

command output.

Behind the bezel, arrays have a label showing the drive numbering for that specific array model:

• In arrays with 2.5-inch drives (installed vertically in a row), the drives are numbered 0-23, left to right.

• In arrays with 3.5-inch drives (installed horizontally), the drives are numbered from left to right and top

to bottom, starting with 0 on the upper left side.

Table 3 shows the drive order for the 3.5-inch drives.

Interpreting Drive LEDs

The LEDs on a 3.5-inch drive are shown in Figure 6. The LEDs on a 2.5-inch drive are shown in Figure 7.

Drive LED states are described in Table 4.
