• If the new drive shelf or drive tray is the only drive shelf in the storage array, attach a cable
between one of the SAS expansion ports on controller A of the controller shelf and a SAS
expansion port 1 on IOM/ESM A of the new drive shelf.
• If the storage array already has one or more drive shelves or drive trays in a single-stack
configuration and the new drive shelf or drive tray has the same type of SAS interface (SAS-2
or SAS-3) as the existing shelves or trays, connect a cable between the SAS expansion port on
IOM/ESM A of the drive shelf or drive tray that was previously the last in the stack and SAS
expansion port 1 on IOM/ESM A of the new drive shelf or drive tray.
• If the storage array already has two or more drive shelves or drive trays in a dual-stack
configuration, connect the new drive shelf or drive tray to the stack of trays or shelves whose
SAS interface (SAS-2 or SAS-3) matches that of the new drive tray or drive shelf. Connect a
cable between the SAS expansion port on IOM/ESM A of the drive shelf or drive tray that was
previously the last in the stack and SAS expansion port 1 on IOM/ESM A of the new drive
shelf or drive tray.
• If the storage array already has one or more drive shelves or drive trays in a single-stack
configuration and the new drive shelf or drive tray has a different type of SAS interface
(SAS-2 or SAS-3) than the existing shelves or trays, you must re-cable the storage array to a
dual-stack configuration. Locate the cable between SAS expansion port 2 on controller A and
IOM/ESM A in the first drive tray or drive shelf in the existing stack. Disconnect that cable
from IOM/ESM A of the tray or shelf in the existing stack and then reconnect it to IOM/ESM
A on the new drive shelf or drive tray. Locate the cable between SAS expansion port 2 on
controller B and IOM/ESM B in the last drive tray or drive shelf in the existing stack.
Disconnect that cable from IOM/ESM B of the tray or shelf in the existing stack and then
reconnect it to IOM/ESM B on the new drive shelf or drive tray.
2. In SANtricity System Manager, click Hardware.
Note: At this point in the procedure, you have only one active path to the controller shelf.
3. Scroll down, as necessary, to see all the of the drive shelves in the new storage array. If the new
drive shelf is not displayed, resolve the connection issue.
4. Select the EOMs/ISMs icon for the new drive tray.
The Shelf Component Settings dialog box appears.
5. If it is not already selected, select the EOMs/ISMs tab in the Shelf Component Settings dialog
box.
6. Select Show more options. Verify the following:
• Both IOM/ESM A and IOM/ESM B are listed.
• Current data rate is 12Gb/s for a SAS-3 drive shelf or 6Gb/s for a SAS-2 drive shelf.
• Card communications is OK.
7. Choose one of the following options:
• If the new drive shelf is the only drive shelf in the storage array, attach a cable between one
(or both) of the SAS expansion ports on controller B of the controller shelf and the SAS
expansion port 1 (or port 1 and port 2) on IOM/ESM B of the new drive shelf.
• If the storage array already has one or more drive shelves or drive trays in a single-stack
configuration and the new drive shelf or drive tray has the same type of SAS interface (SAS-2
or SAS-3) as the existing shelves or trays, identify the cable (or cables) that run from
controller B to the drive shelf that was previously the last drive shelf in the stack. Disconnect
that cable (or those cables) from te SAS expansion port (or ports) of IOM/ESM B on the
original drive shelf and re-connect them to the SAS expansion port (or ports) on IOM/ESM B
