Problems that are caused by trying to import a tape cartridge that was exported by using the  option  --offline  can be solved by reimporting the tape cartridge by using the other options  available. By using  import --recreate  and  –overwrite  (assuming the original path is used),  some of the inodes on IBM Spectrum Scale are overwritten and new inodes are created for  the files that did not have one. At the end of this process, all the files on the tape cartridge  have an inode on IBM Spectrum Scale. Example 7-96 shows an example of importing an offline tape cartridge. Export tape cartridges from your IBM Spectrum Archive EE system by running the  ltfsee  export  command. When you normal export a tape cartridge, the  ltfsee export  command  removes the tape cartridge from the IBM Spectrum Archive EE library. The tape cartridge is  reserved so that it is no longer a target for file migrations. It is then reconciled to remove any  inconsistencies between it and IBM Spectrum Scale.  The export process then removes all files from the IBM Spectrum Scale file system that exist  on the exported tape cartridge. The files on tape cartridges are unchanged by the export, and  are accessible by other LTFS systems. If the  --offline  option is specified, all files from the tape cartridges or tape cartridge pool that  are specified are moved to an offline status and those files cannot be accessed. However, the  corresponding inode of each file is kept in IBM Spectrum Scale. Those files can be brought  back to the IBM Spectrum Scale namespace by reimporting the tape cartridge by using the  --offline  option.  This  --offline  option can be used, for example, when exporting tape cartridges containing  redundant copies to an off-site storage location for disaster recovery purposes. Important:  If the  --offline  option is omitted in the  export  command, all files on the  exported tape cartridge are removed from the GPFS file system. Consider the following information when planning IBM Spectrum Archive EE export activities: Otherwise, you must first recall all the files from the namespace of interest (such as the  project directory), then migrate the recalled files to an empty tape cartridge pool, and then  export that tape cartridge pool. Export considerations GLYPH<SM590000> If you put different logical parts of an IBM Spectrum Scale namespace (such as the project  directory) into different LTFS tape cartridge pools, you can export tape cartridges that  contain the entire IBM Spectrum Scale namespace or only the files from a specific  directory within the namespace.  GLYPH<SM590000> Reconcile occurs automatically before the export is processed. 7.21.2 Exporting Example 7-96 Import an offline tape cartridge [root@ltfssn1 ~]# ltfsee import -p JZJ5WORM -t JZ0072JZ --offline Import of tape JZ0072JZ has been requested. Import of tape JZ0072JZ complete. Updated offline state of tape JZ0072JZ. Chapter 7. Operations  199
