flashcopy backup
Use the flashcopy backup function to create a quick snapshot 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 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 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>
You can use the flashcopy stop function to break the links
between the source and target partitions. Following the
flashcopy stop function, reformat the target partition. All data
on the target partition is invalid after stopping the FlashCopy.
This includes stopping in the middle of a flashcopy backup.
Data is valid during the flashcopy backup and after the
You can override these requirements by using the force
option. See the FlashCopy backup and FlashCopy nobackup
functions for more details.
One or more of the following is true for this partition:
v The partition is in the blocked state.
v The partition is not in the okay or critical state.
v The partition is currently synchronizing, rebuilding, or
migrating.
FlashCopy can support up to four active links only.
There is no partition defined on this logical drive.
