Status of LAN/WAN Replication Connection
You can check that the replication LAN/WAN connection between the source and target devices is
online by viewing "LAN/WAN Replication Libraries" in the source device GUI. If the replication
connection is offline this can be because:
• The target device is "Unreachable" (network problem, target device failure, you manually set the
replication target to be Offline, etc.).
• "Configuration out of Sync" (policy time window settings on the target have been modified to now
conflict with the source replication policy time window).
Also, if tape initialization was selected when configuring the echo copy pool, the replication
LAN/WAN connection is not enabled until tape initialization is complete (or cancelled). If you view
the echo copy pool in the source device GUI the pool state shows the progress of the tape initialization:
• "Awaiting Initialization" (waiting for first full backup to be completed before the "Initiate Tape
Transport" can be triggered).
• "Exporting" (copying the first full backup to tape at the source device).
• "Importing" (copying the exported data from tape into the target device).
Source Device Replication Status
On the source device GUI you can check the replication status of each source virtual cartridge by
viewing "Slots" in a LAN/WAN replication library or by viewing a library in "Source Cartridges".
This lists all the local virtual cartridges being replicated to that target device, with "Last Mirrored"
showing the data of the last successful replication and the "Cartridge Status" showing any active
replication states for each cartridge as shown in the screen shot below:
The "Cartridge Status" allows you to see which cartridges do not have any replicating pending (i.e.,
do not need replicating because they have already replicated or have not been modified because
replication was enabled), which cartridges are on the queue waiting to replicate within the specified
window, and which cartridges are actively replicating over the LAN/WAN link. The "Advanced
Search" task can be used to search for a specific set of cartridges based on barcode string or cartridge
state
The states for cartridges that do not have pending replication are:
• Adding Cartridge. This is when the source virtual cartridge is being initially synchronized to the
target cartridges. This can take a significant time when dealing with a large number of virtual
