Illustrated examples
of simultaneous-write operations show
how the function works in various storage pool configurations. Other
examples show what happens when an error occurs during a simultaneous-write
operation.
Examples of simultaneous-write operations during client store operations
Examples show how the simultaneous-write function
works
during client store operations. In all the examples, client nodes,
whose files require fast restore, are members of a policy domain that
specifies an active-data pool.
Example of migration without a simultaneous-write operation
In this example, the simultaneous-write function to two
copy storage pools is enabled for client store sessions. Files in
the primary storage pool at the top of the storage hierarchy are migrated.
Simultaneous-write operations during migration are not enabled.
Example of a simultaneous-write operation during both migration and a client store operation
In this example, the storage pool hierarchy consists of
a two primary storage pools. A single copy storage pool is defined
to the pools. The simultaneous-write function during client store
operations was enabled. However, one of the backed-up files was not
written to the copy storage pool. The simultaneous-write function
during migration is enabled.
