The hsmreparsetag option specifies a unique reparse tag that is created by an HSM product installed on your system.

Many HSM products use reparse points to retrieve or recall migrated files. After a file is migrated, a small stub file, with the same name as the original file, is left on the file system. The stub file is a reparse point that triggers a recall of the original file when a user or application accesses the stub file. The reparse point includes a unique identifier called a reparse tag to identify which HSM product migrated the file.

If the IBM Spectrum Protect™ backup-archive client does not recognize the reparse tag in a stub file, the Backup-Archive Client causes the HSM product to recall the original file. You can prevent files from being recalled if you specify the reparse tag with the hsmreparsetag option.

The backup-archive client recognizes the reparse tag of HSM products from the following companies:

  • International Business Machines Corp.
  • Wisdata System Co. Ltd.
  • BridgeHead Software Ltd.
  • CommVault Systems, Inc.
  • Data Storage Group, Inc.
  • Enigma Data Solutions, Ltd.
  • Enterprise Data Solutions, Inc.
  • Global 360
  • Hermes Software GmbH
  • Hewlett Packard Company
  • International Communication Products Engineering GmbH
  • KOM Networks
  • Memory-Tech Corporation
  • Moonwalk Universal
  • Pointsoft Australia Pty. Ltd.
  • Symantec Corporation

If the HSM product you use is not in the preceding list, use the hsmreparsetag option to specify the reparse tag. Ask your HSM product vendor for the reparse tag used by the product.
