flashcopy nobackup
link between each source partition and target partition will exist until all the
data is copied. Once all the source data is copied to the target partition
(determined by the ipssend getstatus function), the link is automatically
broken, and you can use the flashcopy delete and flashcopy import
functions to move a logical drive to another system.
You can use the flashcopy map function to determine the partition numbers
and if they are available for the flashcopy backup process.
Notes:
1. Only one flashcopy backup (involving up to four source and target
partitions) can be active on a controller at a time. If a flashcopy backup
is in progress, you cannot issue another flashcopy backup or flashcopy
nobackup until the previous flashcopy backup process is completed or
until the backup links are broken. You can use the flashcopy stop
function to break the links between the source and target partitions.
2. For flashcopy backup to function properly, each target partition must
have the same partition type as its source partition.
3. Do not attempt to write to the target partitions until the backup process is
completed.
Supported operating systems: Windows NT
Command:
ipssend flashcopy controller backup [source target] options
Note: The symbols [ ] above mean that the parameters are repeatable. The
maximum number of repetitions is 4.
where:
controller is the ServeRAID controller number (1–12)
source is the source partition number
Note: Use the flashcopy map function to correlate the ServeRAID
logical drive number to the operating system drive partition
number.
target is the target partition number
Note: Use the flashcopy map function to correlate the ServeRAID
logical drive number to the operating system drive partition
number.
options is an optional parameter that includes the following:
– POLL displays the progress of the backup function.
– FORCE creates a flashcopy of a source partition that is the boot
partition, contains open files, or contains a memory paging file.
Note: Using the FORCE option will not guarantee file consistency
between the source and target partitions.
– NOPROMPT overrides the user prompt.
Use the flashcopy nobackup function to create a quick snapshot impression
of the source partition data on its target partition. Once the snapshot is
created, the source partitions are ready for immediate use. Each target
partition will contain a snapshot of its source partition data that existed at the
exact time you issued the command. A link between each source partition
