Setting The Time Zone; Synchronizing Local Time - IBM System Storage SAN384B-2 Installation, Service And User Manual

Setting the time zone

You must perform the procedure on all chassis for which the time zone must be
set. However, you only need to set the time zone once on each switch, because the
value is written to nonvolatile memory. Use one of the two procedures to set the
time zone.
The procedure describes how to set the current time zone using timezone_fmt
mode to Central Standard time.
1. Log on to the chassis using the admin account. The default password is
2. Enter the tsTimeZone command as follows:
The procedure describes how to set the current time zone using interactive mode
to Pacific Standard Time.
1. Enter the tsTimeZone command as follows:
2. You are prompted to select a general location.
3. Enter the appropriate number or Ctrl+D to quit.
4. At the prompt, select a country location.
5. At the prompt, enter the appropriate number to specify the time zone region or

Synchronizing local time

To synchronize the local time of the principal or primary switch with that of an
external NTP server, follow these steps.
1. If necessary, log on to the switch by Telnet, using the admin account.
2. Enter the tsClockServer command:

switch:admin> tstimezone [--interactive]/ [, timezone_fmt]
Use timezone_fmt to set the time zone by Country/City or by time zone ID,
such as PST. The 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
switch:admin> tstimezone --interactive
Please identify a location so that time zone rules can be set correctly.
Ctrl+D to quit.
switch:admin> tsclockserver "<ntp1;ntp2>"
where ntp1 is the IP address or DNS name of the first NTP server, which the
switch must be able to access. The variable ntp2 is the second NTP server and
is optional. The operand "<ntp1;ntp2>" is optional; by default, this value is
LOCL, which uses the local clock of the principal or primary switch as the
clock server.
The tsClockServer command accepts multiple server addresses in either IPv4,
IPv6, or DNS name formats. When multiple NTP server addresses are passed,
tsclockserver sets the first obtainable address as the active NTP server. The rest
will be 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.
