v endDate
– A specific date on which you want to stop creating an Enhanced FlashCopy logical drive 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
.
v noEndDate
– Use this option if you do not want your scheduled copy-on-write operation to end. If you
later decide to end the copy-on-write operations you must re-enter the
set enhancedFlashCopyGroup
command and specify an end date.
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".
Timezone text strings 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 timeZone=GMT-06:00
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 command
set enhancedFlashCopyGroup ["enhancedFlashCopyGroupName"]
enableSchedule=FALSE
. This command deletes only the schedule, not the Enhanced FlashCopy group.
Set Enhanced FlashCopy Logical Drive Media Scan
This command runs a media scan on the drives used for an Enhanced FlashCopy logical drive.
Optionally, you also can perform a redundancy check on the data.
Syntax
set enhancedFlashCopyLogicalDrive ["
enhancedFlashCopyLogicalDriveName"] mediaScanEnabled=(TRUE | FALSE)
[redundancyCheckEnabled=(TRUE | FALSE)]
Parameters
Parameter Description
enhancedFlashCopyLogicalDrive
The name of the Enhanced FlashCopy logical drive for
which you are setting properties. Enclose the Enhanced
FlashCopy logical drive identifier in double quotation
marks (" ") inside of square brackets ([ ]).
mediaScanEnabled The setting to turn on or turn off media scan for the
Enhanced FlashCopy logical drive. To turn on media
scan, set this parameter to TRUE . To turn off media scan,
set this parameter to
FALSE
. (If media scan is disabled at
the storage subsystem level, this parameter has no
effect.)
