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.
At this point in the procedure, you have only one active path to the controller shelf.
Note:
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 ESMs/IOMs icon for the new drive tray.
The Shelf Component Settings dialog box appears.
5. If it is not already selected, select the ESMs/IOMs tab in the Shelf Component Settings dialog
box.
6. Select Show more options. Verify the following:
• IOM/ESM A is 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
of the new drive shelf. Connect SAS expansion port 1 on IOM/ESM B of the new drive shelf
to the SAS expansion port 1 on the drive shelf that was previously the last in the stack.
• 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 have already fully connected the new
drive tray or drive shelf in step 1.
8. If it is not already selected, select the IOMs (ESMs) tab in the Shelf Component Settings
dialog, and then select Show more settings. Verify that Card communications is YES.
