1.
Log in to the switch using the default password
password
.
2.
Use
timezone_fmt
to set the time zone by Country/City or by time zone ID, such as PST.
The following example shows how to change the time zone to US/Central:
switch:admin> tstimezone
Time Zone : US/Pacific
switch:admin> tstimezone US/Central
switch:admin> tstimezone
Time Zone : US/Central
The following procedure sets the time zone to Pacific Standard Time using interactive mode:
1.
Enter the
tstimezone
command:
switch:admin> tstimezone --interactive
A list of timezones appears followed by a prompt for you to select a general location:
Please identify a location so that time zone rules can be set
correctly.
2.
Enter the appropriate number (an offset of GMT) or press
Ctrl+D
to quit.
3.
At the prompt, select a country location.
4.
At the prompt, enter the appropriate number to specify the time zone region, or press
Ctrl+D
to quit.
Synchronizing local time
You can synchronize the local time of the principal or primary FCS switch to a maximum of eight
external NTP servers. To keep the time current in your SAN, HP recommends that the principal or
primary FCS switch time is synchronized with at least one external NTP server. The other switches
in the fabric automatically take their time from the principal or primary FCS switch.
All switches in the fabric maintain the current clock server value in nonvolatile memory. By default,
this value is the local clock server
LOCL
of the principal or primary FCS switch. Changes to the
clock server value on the principal or primary FCS switch are propagated to all switches in the
fabric.
When a switch has been added to the fabric, the time server daemon of the principal or primary
FCS switch sends the addresses of all existing clock servers and the time to that switch. If a switch
running Fabric OS 5.3.0 or later has been added to the fabric, it can store the list and the active
servers. Switches running Fabric OS 5.3.0 or earlier ignore the new list parameter in the payload
and update only the active server address.
If the active NTP server configured is IPv6, distributing the same information in the fabric is not
possible to switches running Fabric OS versions earlier than 5.3.0, because IPv6 is supported only
for Fabric OS version 5.3.0 and later. The default value
LOCL
is distributed to switches running
Fabric OS 5.3.0 or earlier.
The
tsclockserver
command accepts multiple server addresses in IPv4, IPv6, or DNS name
format. When multiple NTP server addresses are passed,
tsclockserver
sets the first obtainable
address as the active NTP server. The remaining addresses are stored as backup servers that can
take over if the active NTP server fails. The principal or primary FCS switch synchronizes its time
with the NTP server every 64 seconds.
Synchronizing local time using NTP
To synchronize the local time using NTP:
1.
Log in to the switch using the default password,
