 Dear HSM Customer,

 In an effort to provide enhanced storage management software ca-
 pability to our customers, Compaq offers this release of Compaq
 Hierarchical Storage Management (HSM) for OpenVMS[TM] Version 3.0A
 software. Thank you for your recent purchase of this product.

 HSM is a layered software product that extends the OpenVMS file
 system, allowing efficient and cost-effective management of infre-
 quently accessed (dormant) data. This is accomplished by shelving
 the data to lower-cost devices and automatically unshelving it
 when the data is needed.

 HSM V3.0A includes performance enhancements in both the search
 algorithms and the repack command, as well as new qualifiers for
 the repack command. We have also added two new logicals, one to
 allow user defined block size, and the other which allows users
 to define the volume used for temporary files during the unshelve
 operation. For more details on these items, please refer to the
 release notes.

 HSM for OpenVMS V3.0A software has been designed to run on OpenVMS
 VAX Versions 6.2, 7.1, 7.2 and on OpenVMS Alpha Versions 6.2, 7.1,
 7.2 and 7.2-1. The kit you have received is a full release and
 includes both the VAX and Alpha versions of the software. HSM V3.0
 does not support the ODS5 disk structure. The kit includes:

 -  HSM for OpenVMS, V3.0A software and documentation

 -  MDMS for OpenVMS, V3.0B software and documentation

 HSM V3.0A can be configured to run in one of two modes, Basic or
 Plus. If you are using HSM in the Plus mode, you will need to also
 install Media and Device Management Services (MDMS) unless Archive
 Backup System (ABS) software is already present on your system.
 MDMS is also required to use the tape repacking and backup via
 shelving support features of HSM V3.0A.

 Remote access to tape devices in Plus Mode requires Remote Device
 Facility[TM] (RDF). RDF is available through MDMS on the Consoli-
 dated Software CD-ROM. An RDF license is required. An RDF license
 is available through the purchase of Archive Backup System or
 directly from Touch Technologies Inc.

 Due to device issues with DSSI and HSC connected loaders, this
 version of HSM is dropping support for the following loaders:

 -  TF857 and TF867

 -  TA857 and TA867

 We have also added a section to the release notes detailing the
 issues. Please refer to the release notes for more information.

 

 HSM V3.0A supports the use of MDMS V3.0B as well as MDMS V2.9C or
 V2.9D for its media manager.

 For customers using Storage Library Systme (SLS) with HSM, we rec-
 ommend the use of MDMS V2.9D as the media manager. For customers
 using Archive Backup System (ABS) with HSM, we recommend the use
 of MDMS V3.0B. For HSM customers who are not using either ABS or
 SLS, we recommend the use of MDMS V3.0B with HSM V3.0A.

 For additional information, please refer to the product documen-
 tation. If you need assistance with this product, please call the
 Customer Support Center.

 Once again, thank you for your purchase of this product.

 Sincerely,

 Bryan Cox
