Logging in to the switch
The switch supports user-based security that enables you to prevent unauthorized users from
accessing the switch or changing its settings. For more information regarding user-based access,
see the
Fabric OS Administrator’s Guide
.
To log in to the switch, complete the following steps:
1. At the prompt, enter your user ID, then press Enter.
2. Enter your password, then press Enter. The main menu opens.
After you log in to the switch, you must set the date and time. For more information, see
Setting date and time
The IBM Flex System FC5022 16Gb SAN Scalable Switch maintains the current date and time
inside a battery-backed real-time clock (RTC) circuit. Date and time are used for logging events.
Switch operation does not depend on the date and time; a switch with an incorrect date and time
value still functions properly. However, because the date and time are used for logging, error
detection, and troubleshooting, you should set them correctly.
Time zones
You can set the time zone for the switch by name. You can also set the country and city, or time
zone parameters.
If the time zone is not set with the new options, the switch retains the offset time zone settings. The
tsTimeZone command includes an option to revert to the prior time zone format. For more
information about the
--
old option, see the
Fabric OS Command Reference
.
You can set the time zone for a switch using the tsTimeZone command. The tsTimeZone command
allows you to perform the following tasks:
•
Display all of the time zones supported in the firmware
•
Set the time zone based on a country and city combination or based on a time zone ID, such as
PST
The time zone setting has the following characteristics:
•
You can view the time zone settings. However, only those with administrative permissions can
set the time zones.
•
The tsTimeZone setting automatically adjusts for Daylight Saving Time.
•
Changing the time zone on a switch updates the local time zone setup and is reflected in local
time calculations.
•
By default, all switches are in the Greenwich Mean Time (GMT) time zone (0,0). If all switches
in a fabric are in one time zone, it is possible for you to keep the time zone setup at the default
setting.
•
System services that have already started reflect the time zone changes only after the next
reboot.
•
Time zone settings persist across failover for high availability.
