The following information explains the FlashCopy functions in more detail.
Function What it does Command
flashcopy
backup This function creates a snapshot of the
data contained on the source partitions and
writes it to the corresponding target
partitions. The link between each source
partition and target partition exists until all
the data is copied; then, the operation is
complete and the link is automatically
broken. At this point, the source partitions
are ready for immediate use, and each
target partition contains a valid copy of the
source partition data that existed at the
exact time you issued the FlashCopy
backup command. The physical drives
containing the target partitions can be
removed and used with another
ServeRAID controller. IPSSEND FLASHCOPY controller BACKUP {source
target} [POLL] [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 POLL is an optional parameter that displays the
progress of the backup function.
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 backup process (involving up to
four source and target partitions) can be active on a
controller at a time. If a FlashCopy backup process is
in progress, you cannot issue another FlashCopy
backup or FlashCopy nobackup command until the
previous FlashCopy backup process is completed.
2. You must initiate multiple FlashCopy links at the
same time. If you want to initiate four FlashCopy
links, you
must initiate the links on the same
command. For example:
IPSSEND FLASHCOPY BACKUP 1 2 3 4 5 6 7 8
You cannot initiate the four links across multiple
commands, such as the following:
IPSSEND FLASHCOPY BACKUP 1 2 3 4
IPSSEND FLASHCOPY BACKUP 5 6 7 8
flashcopy
delete This function deletes an array. You can use
the ServeRAID Manager program to
identify the array you want to delete. This
program can make the LEDs flash for the
physical drives that belong to the specific
array.
Note: The FlashCopy delete function is
not available in a cluster configuration.
Important: If your target logical drive is
configured with write-back cache enabled,
wait 10 minutes after the FlashCopy
backup is completed before issuing a
FlashCopy delete command. This ensures
that all data has been moved from the
controller cache to the logical drive.
IPSSEND FLASHCOPY controller DELETE arrayID
[NOPROMPT]
where:
v controller is the ServeRAID controller number (1–12)
v arrayID is one of the following:
– For a nonspanned array: (A–H)
– For a spanned array: (1–8)
v NOPROMPT is an optional parameter that overrides
the user prompt.
