Setting The Switch Date And Time; About Setting Time Zones - HP StorageWorks 8/40 - SAN Switch Hardware Reference Manual

Setting the switch date and time

The 8-Gb SAN Switch maintains the current date and time inside a battery-backed real-time clock
(RTC) circuit. Switch operation does not depend on the date and time. An 8-Gb SAN Switch with an
incorrect date and time value still functions properly. However, it is important that your switch shows
the accurate date and time, because these are used for logging, error detection, and troubleshooting.
1. Log in to the switch using the default password, (password).
2. Enter the date command:
date "mmddHHMMyy"
The values represent the following:
• mm is the month; valid values are 01 through 12.
• dd is the date; valid values are 01 through 31.
• HH is the hour; valid values are 00 through 23.
• MM is minutes; valid values are 00 through 59.
• yy is the year; valid values are 00 through 99. (Values greater than 69 are interpreted as
1970 through 1999, and values less than 70 are interpreted as 2000-2069.)

About setting 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 Manual.
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.
• 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 savings 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 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 will reflect the time zone changes only after the next
reboot.
