11.2 Replication Send
Synchronizing a Share or Partition
Synchronize a NAS share or VTL partition to synchronize its contents with the
corresponding share or partition on the target systems. To synchronize a share or
partition, it must be configured for Directory/File or Cartridge Based Replication (see
"Configuring Directory/File or Cartridge Based Replication" on page 351).
Synchronizing a share or partition ensures that the contents of the source share or
partition are the same as the target share or partition. The synchronization verifies that
the same files or cartridges exist in both locations, and that no additional files or
cartridges exist in either location.
You should perform a synchronization in any of the following situations:
l When Directory/File or Cartridge Based Replication is first enabled for a share or
partition.
l If a Directory/File or Cartridge Based Replication job fails.
l If Directory/File or Cartridge Based Replication is disabled for a time and then is re-
enabled.
Manually performing a synchronization is not necessary except in the cases described
above. When synchronization is manually initiated for a share or partition, the replication
queue for that share or partition is cleared. All file write and delete requests are queued
after the synchronization, and they are not processed until the synchronization is
complete. This can cause replication to appear to be slow, especially for a share or
partition that is frequently accessed.
CAUTION!
Before synchronizing a share or partition, make sure all media are unmounted and
there are no active backup jobs to the share or partition. (After the synchronization
reaches the Replicating state, backup jobs are allowed.)
Even when replication is paused, the system continues to queue Directory/File or
Cartridge Based Replication operations. Each time an operation is queued, the
system logs an administration alert that reports the total number of queued
Directory/File or Cartridge Based Replication requests.
If a synchronization fails, make sure the target share or partition is unlocked
(see "Configuring a Target Share for Directory/File Based Replication" on page
365 or "Configuring a Target Partition for Cartridge Based Replication" on page
376.)
To synchronize a share or partition:
1. Select the share or partition to synchronize.
If multiple targets are configured, click the arrow next to the share or partition to
display all targets, and then select the desired target.
2. Click Synchronize Now.
