flashcopy backup
Use the flashcopy backup function to create a quick snapshot
impression of source partitions on corresponding target partitions.
Once the snapshot is created, the source partitions are ready for
immediate use. When the process completes, each target partition
will contain a copy of its source partition data that existed at the
exact time you issued the flashcopy backup function. A 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
server.
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.
