Tape Tab

If the Platform System is licensed to use LTO Tape backup and archiving, the tape tab allows the administrator to set configuration options for this feature.

Allow Spanning Tapes

Allow Tape Spanning must be turned on if a user wants to run an Archive or Backup operation across more than one tape. If an administrator wishes to keep individual tape jobs from writing to only one tape, they will keep this option off.

Allow Spanning Tapes: Off – If deselected, when a backup or archive operation is requested, the system will pre-check to see if there is enough space on the target tape to complete the operation. The Platform performs a conservative estimate attempting to ensure that the tape selected will have enough room to complete the job. This is a warning only and the operator will be allowed to submit the job even when the warning has been issued. When a job reaches the end of the tape and not all the data is written, the following occurs:

Backup Job – a notification warning is issued to the user that not all files in the backup were written to tape before the job finished. However, files written to tape will remain on tape and recorded in the catalog.

Archive Job – a notification error is issued to the user that the archive failed. The files written to the tape are removed and the tape is placed back to the position before the job started.

Allow Spanning Tapes: On – If selected, when a backup or archive operation is requested, the system will ignore all checks and begin the operation on the tape selected. If the tape fills up before the job is completed, the system will rewind the current tape, eject it, and will issue a notification warning that another tape must be inserted.

Auto-Import / Sync Tapes upon Insert

auto import

This option is selected by default and will cause the system to automatically perform a Platform Tape import or Catalog Sync operation when a new tape is inserted into a tape drive. If the system attempts to automatically sync a tape and an error occurs, the error will be listed next to the tape drive so the operator can correct the issue.

Scratch Location

scratch location

The Platform LTO tape management system uses a ‘scratch’ location for certain tape operations including some MD5 checksum operations. This scratch location must be specified in order to properly configure the tape operation. The administrator should choose a scratch location that has least enough space for the largest single file they will write or read from a tape. When the tape system starts, it will create a directory called ‘PromaxScratch’ on the storage group specified.

Cache-A Database Import

cachea database import

Designed for existing ProMAX / Cache-A Customers to easily transition to the ProMAX Platform system, the Cache-A Database Import process is used to import an existing set of tar XML TOC files into the Platform Catalog. After this import is complete, all files and folders copied to any Cache-A tar tape will be searchable in the Platform system.

Only Cache-A Tar tapes will be imported during this process. Unfortunately, LTFS TOC files do not contain the necessary information to perform an import. LTFS tapes must be inserted into a tape drive individually which will perform an import for that tape.

Step 1. The first step in the database import process is to back up the Cache-A database catalog to a tape which is an option in the administrative section of the Cache-A interface. That tape can then be inserted into the Platform System and the Cache-A database backup can be restored to a Platform Space the administrator wishes to use.

Step 2. When the Cache-A database backup has been restored to a Platform Space, there will be a tar archive file saved in the space. This has the format ‘databasefile.tgz’. The administrator will need to extract all the data from that archive into the Platform Space. The files in this archive are individual tape TOC (Table of Contents) files from the Cache-A database which end in the suffix ‘XML’. The administrator must note the directory within the Platform Space that these files are saved to.

Step 3. Next, in the Platform Configuration screen, Tape Tab, the administrator will select the Platform Space that these files were saved to. After selecting the Platform Space, the operator will click on the ‘Go’ button.

Step 4. The Platform interface will then bring up a window allowing the administrator to select the director where the ‘XML’ files have been stored.

After selecting the directory, the administrator will click on the ‘Confirm’ button.The system will then submit a ‘Sync Catalog’ task to the Task System to process the import
