22.5.3 Commonly used disaster recovery queries Note:  For more information about using the ptcli tool, see the command-line interface topic  in  IBM System Storage TS7600 with ProtecTIER Version 3.3 , SG24-7968. The following list describes several commonly used DR queries that you can run: GLYPH<SM590000> To create a snapshot of the current replication status, run the following command: GLYPH<SM590000> To list all in-sync cartridges, run the following command:  GLYPH<SM590000> To list all unsynchronized cartridges marked with dirty bit, run the following command:  GLYPH<SM590000> To list cartridges synchronized with the destination at a certain time range on the source,  run the following command:  GLYPH<SM590000> To list all cartridges that are replicated to repository 18 in grid 1, run the  following command:  GLYPH<SM590000> To list all cartridges in bar code range BR0300 - BR0330, run the following command:  GLYPH<SM590000> To move all synchronized cartridges to the shelf, run the following command:  ./ptcli InventoryMoveFilter --ip xxx.xxx.xxx.xxx --querytype replica --query  "in_sync = true" -destination shelf -login file ./ptcli InventoryFilter --ip xxx.xxx.xxx.xxx --querytype all --query "bar code  > BR0300 and bar code < BR0330" -login file -output barcodes_file  ./ptcli InventoryFilter --ip xxx.xxx.xxx.xxx --querytype origin --query  "destination_repository_id = 18 and destination_grid_id = 1" -login file  ./ptcli InventoryFilter --ip xxx.xxx.xxx.xxx --querytype replica --query  "source_time_for_last_sync_point > datetime(?2009-11-13 08:00:00')" -login file  ./ptcli InventoryFilter --ip xxx.xxx.xxx.xxx --querytype replica --query  "in_sync = false" -login file -output /tmp/dirty_carts ./ptcli InventoryFilter --ip xxx.xxx.xxx.xxx --querytype replica --query  “in_sync = true” –login file –output /tmp/not_dirty_carts ./ptcli InventoryRefresh --ip xxx.xxx.xxx.xxx -login file Important:  Creating a snapshot must be done before you run any other queries. Before  you begin to filter the cartridges or to move cartridges by using the CLI, you must create  a snapshot of the cartridges by running  InventoryRefresh . This snapshot captures the  current properties of all cartridges. Any filter or move operation is run based on the  content of the snapshot. Moving a cartridge before you create a snapshot might fail if  the snapshot is not up-to-date (not taken directly before the move). 22.5.4 Returning to normal operations Failback This section explains the meaning of failback and failback policy, and provides the steps for  using the ProtecTIER Manager failback wizard.  Failback is the procedure for returning visibility to the primary site and replicating any new  data that is created at the DR site to the original (or replaced) primary repository. You use  failback to return to the original working mode of the primary site.  406  IBM ProtecTIER Implementation and Best Practices Guide
