fails to respond to one of these checks, the IMM generates an OS

timeout alert and restarts the server. After the server is restarted, the

OS watchdog is disabled until the operating system is shut down and

the server is power cycled.

To set the OS watchdog value, select a time interval from the menu. To

turn off this watchdog, select 0.0 from the menu. To capture

operating-system-failure screens, you must enable the watchdog in the

OS watchdog field.

Loader watchdog

Use the Loader watchdog field to specify the number of minutes that

the IMM waits between the completion of POST and the starting of the

operating system. If this interval is exceeded, the IMM generates a

loader timeout alert and automatically restarts the server. After the

server is restarted, the loader timeout is automatically disabled until

the operating system is shut down and the server is power cycled (or

until the operating system starts and the software is successfully

loaded).

To set the loader timeout value, select the time limit that the IMM waits

for the operating-system startup to be completed. To turn off this

watchdog, select 0.0 from the menu.

Setting the IMM date and time

The IMM uses its own real-time clock to time stamp all events that are logged in

the event log.

Note: The IMM date and time setting affects only the IMM clock, not the server

clock. The IMM real-time clock and the server clock are separate,

independent clocks and can be set to different times. To synchronize the

IMM clock with the server clock, go to the Network Time Protocol area of

the page and set the NTP server host name or IP address to the same server

host name or IP address that is used to set the server clock. See

“Synchronizing clocks in a network” on page 18 for more information.

Alerts that are sent by e-mail and SNMP use the real-time clock setting to time

stamp the alerts. The clock settings support Greenwich mean time (GMT) offsets

and daylight saving time (DST) for added ease-of-use for administrators who are

managing systems remotely over different time zones. You can remotely access the

event log even if the server is turned off or disabled.

To verify the date and time settings of the IMM, complete the following steps:

1. Log in to the IMM where you want to set the IMM date and time values. For

more information, see Chapter 2, “Opening and using the IMM Web interface,”

on page 9.

2. In the navigation pane, click System Settings and scroll down to the IMM

Date and Time area, which shows the date and time when the Web page was

generated.

3. To override the date and time settings and to enable daylight saving time (DST)

and Greenwich mean time (GMT) offsets, click Set IMM Date and Time.

4. In the Date field, type the numbers of the current month, day, and year.

5. In the Time field, type the numbers that correspond to the current hour,

minutes, and seconds in the applicable entry fields. The hour (hh) must be a
