Option Description
To install a drive tray that has
previously been installed in a
storage array. (If the
installation history of the
drive tray that you are
installing is unknown, you
should assume that it has
been previously installed in a
storage array.) Remove the drives before you continue with step 2 on page 100. The
drives must be installed one at a time later in this procedure.
To install a new drive tray and
drives that have never
previously been installed in a
storage array. Continue with step
2
on page 100.
2. Install the new drive tray in the rack that holds the storage array components.
Attention: See the installation instructions for your model for the full procedure for physical
installation and power cabling. The installation instructions for your model includes notes and
warnings that you must take into account to safely install a drive tray.
3. Power on the new drive tray and confirm that no amber warning LEDs are illuminated on the
drive tray. Resolve any fault conditions indicated by the LEDs before you continue with this
procedure.
Connecting the drive tray
Perform these steps to connect a new drive shelf (drive tray) while power is still applied to the other
components of a storage array.
About this task
You may add a new drive tray while power is still applied to the other components of the storage
array so that access to data is not interrupted. Refer to the examples of drive cabling topology earlier
in this chapter that apply to the hardware of your storage array. If your storage array did not
previously have a drive tray, you will cable the new drive tray as shown for the examples of a storage
array with one drive tray. If your storage array already has one or more drive trays, this procedure
describes how to change the cabling of the drive tray that was previously the last in a stack to connect
to the new drive tray as the last in that stack. (You can add the new drive tray before the first drive
tray in an existing stack. In that case you must modify this procedure accordingly.)
If you have an E2800 or E5700 storage array and manage your storage array with SANtricity System
Manager, use the tasks in
Using SANtricity System Manager to add a drive shelf (drive tray) to an
existing storage array
on page 102 to add a new drive tray to your storage array
Note:
If you are adding the new drive tray to a storage array using a dual-stack cabling, the
resulting configuration should have an equal number of drive trays in each stack, or, at most, one
more drive tray in one stack than the other.
Note: If you are adding the new drive tray to a storage array with one controller (simplex
configuration), modify the steps in this procedure as necessary to cable only the controller A drive
channel. Multiple connections between a controller and an environmental services module (ESM)
are not supported in a simplex configuration.
Note:
If you are adding a DE6600 drive tray to the storage array, the drives in the front four bays
in each of the five drawers must be installed before you begin this procedure. The drives in the
remaining open drive bays are installed later in this procedure.
Connect the cables in the order given in the following steps.
