PS5000 Hardware Maintenance
connected to the port on the active control module. Therefore, you should connect
a cable to the network interface port on each control module to ensure that both
control modules can access an interface.
A PS5000 array provides two types of network failure protection:
Network connection failover. If multiple network interfaces are configured
and one network interface fails, iSCSI initiators that were connected to the
failed interface can reconnect to the group IP address and be redirected to a
functioning interface. For example, in a single control module array, if
Ethernet 0 and Ethernet 1 are connected to a network, and Ethernet 0 fails,
initiators that were connected to Ethernet 0 can be redirected to Ethernet 1.
Control module failover. In a dual control module array, if the active control
module fails, the secondary automatically takes over and becomes active. If a
cable is connected to the port on the newly active control module, network I/O
can continue through that interface. Control module failover is transparent to
applications, but iSCSI initiators must reconnect to the group IP address.

Maintaining Control Module Firmware

A PS5000 array includes one or two control modules, each with a compact flash
card running the array firmware. You should run the latest firmware version to
take advantage of new product features and enhancements.
Caution: In a dual control module array, both control modules must be running
the same firmware version; otherwise, only one control module will be
functional. When you use the
control modules are updated to the same firmware version.
Group members should run the same firmware version; otherwise, only
functionality common to all versions will be available in the group. See the
PS Series Release Notes for information about mixed-firmware groups.
If you are upgrading to a dual control module array or replacing a failed compact
flash card, be sure to order the correct PS Series firmware version. If you are
replacing a failed control module, remove the compact flash card from the failed
control module and install it in the replacement control module. This will ensure
that you retain the correct firmware.
A new compact flash card will show the firmware version on the label. To display
the firmware version running on an array, examine the GUI Member Controllers
window or use the CLI
firmware on a compact flash card does not match the firmware running on an
array, do not install it. Instead, contact your array support provider.
