Monitoring the EIP card
Some array models include an Enclosure Interface Processor (EIP) card. An array continues to operate if the
EIP card fails. You can replace the failed EIP card with no impact on group operation.
In the Member Enclosure window, the EIP card panel shows the EIP card status.
Table 15-18 describes EIP card status, descriptions, and how to solve any issues.

Monitoring control modules
Each group member has one or two control modules installed. One control module is designated as active
(responsible for serving I/O to the member). On the active control module the LED labeled ACT is lit.
In a dual control module array, the othe
r control module is secondary (mirrors cache data from the active control
module). Upon startup, either control module can be designated active or secondary, regardless of its previous
status.
Under normal operation, the status of a control module (active or secondary) does not change, unless
you restart the
member.
In a single control module array, if the control module fails, the member is of
fline.
In a dual control module array, if the active control module fails, the
secondary control module becomes active and
begins serving I/O. This is called control module failover. I/O should continue if you connect cables to the newly
active control module.
For information about replacing control modules, see the Hard
ware Maintenance manual for your array model or
contact your PS Series support provider.
To display control module information, click
Group, then expand Members, then select the member name, and
then click the
Controllers tab.
Each Control Module Slot panel shows the following information:
•
Status. See Table 15-19.
• Boot time.
