Executing an IPL
Selecting IPL causes the Ethernet connection between the switch and HAFM appliance to drop
momentarily. It also causes the following to occur in the Element Manager window:
• As the network connection drops, the switch Status table on the Hardware view turns yellow.
• The Status field in the table displays
No Link
and the State field displays the reason for no
link.
• A gray square is displayed in the status bar. See Table 3 on page 41 for an explanation of this
status bar display.
• The FRUs illustrated in the Hardware view do not display. They display again after the
connection is re-established.
Results of executing an IPL
Executing an IPL initiates the following functions in the switch:
• Restarts the operational firmware on the CTP card and executes abbreviated power on system
tests (POSTs). Then, if no POST errors are encountered, the switch resumes the active role that it
had before the IPL.
• Resets the Ethernet interface on the CTP card, causing the connection to the HAFM appliance to
drop momentarily. The status icon for the switch in the Physical/Topology Map changes to a
gray square until the connection is reestablished.
After the IPL:
• All Fabric services databases containing information about current Fabric logins, name server
registrations, and other data remain intact, making the operation transparent to attached
devices.
• The switch returns to the online state, even if it was off line before the operation.
All ports configured as blocked will remain blocked.
CAUTION: The Ethernet connection between the HAFM appliance and the switch is interrupted
momentarily during an initial program load (IPL). However, this does not interrupt Fibre Channel
traffic.
CAUTION: An IPL is not intended for ordinary or casual use and should only be performed if the
control processor (CTP) is suspected to be faulty. Do not use this option unless directed by your
support representative or if you need to set the CTP.
