Chapter 2: Upgrading Trays in the Storage Array
ATTENTION Possible equipment damage – Only a qualified service technician
should perform this procedure, or equipment damage might result.
Use this procedure to upgrade a host interface card (HIC). The replacement HIC can
have iSCSI, SAS, or Fibre Channel connections.
The E2660 controller-drive tray can mix host interfaces of different types, with some
restrictions. In all cases, when host interface types are mixed, both controllers in a
duplex controller-drive tray must have the same arrangement of HICs. Each controller
must have the same type of HIC in the same relative position as the other controller.
ATTENTION Possible data loss – If you remove all Fibre Channel HICs from a
storage array and replace them with HICs of a different network protocol (such as
iSCSI or SAS), you must first deactivate the Remote Volume Mirroring (RVM)
premium feature if it is activated. If you do not deactivate the RVM before removing
the Fibre Channel HICs, your system loses data access and data loss might occur.
NOTE iSCSI host ports do not support the Data Assurance (DA) premium feature.
NOTE IB host ports do not support the Data Assurance (DA) premium feature.
ATTENTION Potential loss of connectivity – If both controllers in a duplex
controller-drive tray are powered up at the same time with different types of HICs, a
mismatch results that causes both controllers to lock down (shut down and stop
operating). If one controller is already running, and you replace the alternate controller
with a different HIC, then only the replacement controller locks down, and the running
controller remains operational.
Before you upgrade or replace a HIC, gather antistatic protection and a new HIC. If
you are changing your current configuration, you might need to replace these items in
addition to the HIC:
Small Form-factor Pluggable (SFP) transceivers.
Ethernet cables.
Host bus adapters.
Host-channel adapters.
Cables – Both SAS and iSCSI use copper cable, and Fibre Channel uses copper
cable and fiber-optic cable.
The correct host interface card subplate for the front of the controller (which is
included in this kit).
