Replacing Controller Canisters in the E5660 Controller-Drive
Tray to Upgrade Host Interface Cards
To access this product, go to the NetApp® support site at mysupport.netapp.com.
Planning the Host Interface Card Upgrade
Use these procedures to upgrade the host interface in a controller-drive tray by replacing all of the controllers. For
duplex controller-drive trays, you replace both controllers. For simplex controller-drive trays, you replace the one
controller. In both cases, you must power off the controller-drive tray. As a result, you cannot access data on the
storage array until you successfully complete the replacement.
If your storage array participates in remote volume mirroring, only iSCSI or Fibre Channel connections are
supported between the primary site and the remote site. If your new HIC configuration does not include iSCSI or
Fibre Channel connections, remote volume mirroring will not be supported.
If you upgrade to 56 Gb/s InfiniBand, you must perform the steps from the InfiniBand Configuration and Provisioning
for Linux® Express Guide to configure your storage array to use the iSCSI Extensions for RDMA (iSER) protocol.
Make sure that you have access to that document before you start these procedures.
To complete this procedure, you will need antistatic protection and one or two new controller canisters. Depending
on your new host interface, you might need new host bus adapters (HBAs), host channel adapters (HCAs),
switches, cables, Small Form-factor Pluggable (SFP) transceivers, or quad SFP (QSFP) transceivers to re-cable
your host connections. Table 1 summarizes requirements for cabling and SFP transceivers.
Your new controller canisters are shipped without a battery installed. You will remove the battery from each of your
old controllers and then install those batteries in the new controllers.
ATTENTION Possible loss of data access – If any controller that you are replacing manages any secure volumes,
the new controller needs the correct security key to manage those volumes. After you replace the controller and
restore power to the controller-drive tray, you can use SANtricity Storage Manager to load the key from the file in
which it was saved. Be sure that such a file exists and that you know the pass phrase required to install the security
key before you replace the controller.
Cabling Considerations for the E5600 Controller-Drive Trays
Compare your current host cabling to the supported cabling for your new controllers to determine whether you can
reuse SFPs, QSFPs or cables from your old cabling configuration. The HBAs, HCAs, or Ethernet adapters, as well
as switches in the network fabric used to connect your hosts to your storage array must match the HICs in your
controller canisters.
