Function What it does Command
flashcopy
nobackup This function creates a snapshot of the
data contained on the source partitions;
however, it does not back up the entire
contents of the source partitions to the
target partitions. The snapshot exists only
while there is a link between the source
and target partitions. The link between the
source and target partitions exists until you
issue the FlashCopy stop all command.
After you issue the FlashCopy stop all
command, the target partition is no longer
accessible. Compared to the FlashCopy
backup command, the FlashCopy
nobackup command requires less internal
ServeRAID processing and disk accesses;
it has a smaller impact on performance. IPSSEND FLASHCOPY controller NOBACKUP {source
target} [FORCE] [NOPROMPT]
where:
v controller is the ServeRAID controller number (1–12)
v source is the source partition number, and target is
the target partition number. The maximum number of
repetitions of
{source target} is four.
v FORCE is an optional parameter that creates a
FlashCopy of a source partition that is the boot
partition and either contains open files or a memory
paging file.
Note: Using the FORCE option will not guarantee file
consistency between the source and target partitions.
v NOPROMPT is an optional parameter that overrides
the user prompt.
Notes:
1. Only one FlashCopy nobackup link (involving up to
four source and target partitions) can exist on a
ServeRAID controller. If a FlashCopy nobackup
function is invoked, you cannot issue another
FlashCopy nobackup or FlashCopy backup
command until existing nobackup links are broken.
2. You must initiate multiple FlashCopy links at the
same time. For example, if you want to initiate four
FlashCopy links, you
must initiate the links on the
same command:
IPSSEND FLASHCOPY NOBACKUP 1 2 3 4 5 6 7 8
You cannot initiate the four links across multiple
commands, such as the following:
IPSSEND FLASHCOPY NOBACKUP 1 2 3 4
IPSSEND FLASHCOPY NOBACKUP 5 6 7 8
flashcopy
stop all This function breaks all open links between
the source and target partitions. After you
issue the FlashCopy stop all command, the
target partition contents are no longer
accessible and you must reformat your
target partitions. This includes stopping in
the
middle of a FlashCopy backup
operation. Data is valid during the
FlashCopy backup and after the FlashCopy
backup is completed, but not after a
FlashCopy stop is issued during a
FlashCopy backup procedure.
Note: After a FlashCopy stopall command
is executed, the ServeRAID Manager
program will display an event indicating
that the FlashCopy has failed. This is
normal.

where:
v
controller is the ServeRAID controller number (1–12)
v NOPROMPT is an optional parameter that overrides
the user-prompt.
