5. Optionally, verify that the address was correctly set by entering the
ipAddrShow command at the prompt.
6.
Record the IP address on the pull out tab provided for this purpose on the port
side of the switch.
Setting the switch date and time
The SAN48B-5 maintains the current date and time inside a battery-backed
real-time clock (RTC) circuit. The date and time settings 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.
Complete the following steps to set the date and time of the switch.
Time zones
You can set the time zone for the switch by name. You can also set country, 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:
v
Display all of the time zones supported in the firmware
v 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:
v
You can view the time zone settings. However, only those with administrative
permissions can set the time zones.
v
The
tsTimeZone
setting automatically adjusts for Daylight Savings Time.
v Changing the time zone on a switch updates the local time zone setup and is
reflected in local time calculations.
v
By default, all switches are in the 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.
v System services that have already started will reflect the time zone changes only
after the next reboot.
v
Time zone settings persist across failover for high availability.
For more detailed information about the parameters of the tsTimeZone command,
refer to the Fabric OS Command Reference .
Local time synchronization
You can synchronize the local time of the principal or primary fabric configuration
server (FCS) switch to a maximum of eight external network time protocol (NTP)
servers. To keep the time in your SAN current, it is recommended that the
principal or primary FCS switch has its time synchronized with at least one
