v endDate
– A specific date on which you want to stop creating an Enhanced FlashCopy image and end
the copy-on-write operation. The format for entering the date is MM:DD:YY. An example of this option
is
endDate=11:26:11
.
noEndDate
is a value that can be specified for the
endDate
parameter.
v timesPerDay
– The number of times that you want the schedule to run in a day. An example of this
option is
timesPerDay=4
.
v timeZone
– Use this parameter to define the time zone in which the storage subsystem is operating.
You can define the time zone in one of two ways:
–
GMT±HH:MM
– The time zone offset from GMT. Enter the offset in hours and minutes. For example
GMT-06:00 is the central time zone in the United States.
– Text string – Standard time zone text strings. For example: " USA/Chicago " or " Germany/Berlin ". Time
zone text strings s are case sensitive. If you enter an incorrect text string, GMT time is used. Enclose
the text string in double quotation marks.
The code string for defining a schedule is similar to these examples:
enableSchedule=true schedule startTime=14:27
enableSchedule=true schedule scheduleInterval=180
enableSchedule=true schedule scheduleInterval=180
enableSchedule=true schedule timeZone="USA/Chicago"
If you also use the
scheduleInterval
option, the firmware chooses between the
timesPerDay
option and
the
scheduleInterval
option by selecting the lowest value of the two options. The firmware calculates an
integer value for the
scheduleInterval
option by dividing 1440 by the
scheduleInterval
option value
that you set. For example,
1440/180 = 8.
The firmware then compares the
timesPerDay
integer value
with the calculated
scheduleInterval
integer value and uses the smaller value.
To remove a schedule, use the
delete logicaldrive
command with the schedule parameter. The
delete
logicaldrive
command with the schedule parameter deletes only the schedule, not the Enhanced
FlashCopy logical drive.
The
enableSchedule
parameter and the
schedule
parameter provide a way for you to schedule automatic
Enhanced FlashCopy. Using these parameters, you can schedule Enhanced FlashCopy daily, weekly, or
monthly (by day or by date). The
enableSchedule parameter turns on or turns off the ability to schedule
Enhanced FlashCopy. When you enable scheduling, you use the schedule parameter to define when you
want the Enhanced FlashCopy to occur.
This list explains how to use the options for the schedule parameter:
v immediate
– As soon as you enter the command, an Enhanced FlashCopy logical drive is created, and a
copy-on-write operation begins.
v startDate
– A specific date on which you want to create an Enhanced FlashCopy logical drive and
perform a copy-on-write operation. The format for entering the date is MM:DD:YY. If you do not
provide a start date, the current date is used. An example of this option is
startDate=06:27:11
.
v scheduleDay
- A day of the week on which you want to create an Enhanced FlashCopy logical drive
and perform a copy-on-write operation. You can enter these values: monday, tuesday, wednesday,
thursday, friday, saturday, and sunday . An example of this option is scheduleDay=wednesday .
v startTime
– The time of a day that you want to create an Enhanced FlashCopy logical drive and start
performing a copy-on-write operation. The format for entering the time is HH:MM, where HH is the
hour and MM is the minute past the hour. Use a 24-hour clock. For example, 2:00 in the afternoon is
14:00. An example of this option is
startTime=14:27
v scheduleInterval
– An amount of time, in minutes, that you want to have as a minimum between
copy-on-write operation. You can possibly create a schedule in which you have overlapping
copy-on-write operations because of the duration a copy operation. You can make sure that you have
time between copy-on-write operations by using this option. The maximum value for the
scheduleInterval
option is 1440 minutes. An example of this option is
scheduleInterval=180
.
