IBM Netfinity User's Reference: ServeRAID
Note: Use the flashcopy map function to correlate the
ServeRAID logical drive number to the operating system
drive partition number.
v 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.
v 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 and its target
partition will exist until you issue the flashcopy stop function. Once
you issue the flashcopy stop function, each target partition
contents are no longer valid. The flashcopy nobackup function is
useful if you want a snapshot of your data to perform a tape
backup.
You can use the flashcopy map function to determine the partition
numbers and if they are available for the flashcopy nobackup
function process.
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 backup or flashcopy nobackup function
until existing nobackup links are broken. You can use the
flashcopy stop function to break the links between the source
and target partitions.
2. For the flashcopy nobackup function to operate properly, each
target partition must have the same partition type as its source
partition.
3. Do not attempt to write to the target partition until the nobackup
link is broken.
