HP StorageWorks 2.32 Edge Switch - Manual (Page 136)

Using maintenance features 136
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.
If it is necessary to execute an IPL on the switch, use the following steps:
1. Select Maintenance > IPL. A dialog box appears prompting you to continue the IPL.
Figure 63 IPL Confirmation dialog box
2. If you want to continue the IPL, click Yes.
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 box in the table displays
No Link
and the State box displays the reason for no
link.
• A gray square appears in the status bar. See Table 2 on page 37 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.
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 will change 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 offline before the operation.
• All ports configured as blocked will remain blocked.
Setting online state
Use the procedure in this section to display the current switch operating state (offline or online) and
change the state as required. See Table 2 on page 37 for more information on the switch operating
states.
