 Dear HSM Customer,

 In an effort to provide advanced storage management software ca-
 pability to our customers, Digital offers Hierarchical Storage
 Management (HSM) for OpenVMS[TM] Version 2.2 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 for OpenVMS Version 2.2 software has been designed to run
 on OpenVMS Versions 6.1 through V7.1 on the VAX[TM]and Alpha[TM]
 platforms. The kit you have received is a full release and in-
 cludes both the VAX and Alpha versions of the software. The kit
 includes:

    HSM for OpenVMS, Version 2.2 software and documentation
    MDMS for OpenVMS, Version 2.9A software and documentation

 HSM V2.2 can be configured to run in one of two modes, Basic or
 Plus mode. If you are using HSM in the Plus mode, you will need
 to also install Media and Device Management Services (MDMS) unless
 the Storage Library System (SLS) software is already present on
 your system. MDMS is also required to use the tape repacking and
 backup via shelving support features of HSM Version 2.2. Refer to
 the Release Notes for more information on HSM features, changes,
 and restrictions. The HSM software kit (HSM022) is installed with
 the VMSINSTAL command procedure as described in the Installation
 and Configuration Guide, also found in the software kit. The HSM
 Guide to Operations, HSM Command Reference Guide, and HSM Instal-
 lation and Configuration Guide are found in the online documen-
 tation CD-ROM and may be ordered separately in hard-copy format.
 MDMS information is incorporated throughout the HSM documentation
 set.

 If you need assistance with this product, please call the Customer
 Support Center.

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

 Sincerely,

 Dan Barrett
 HSM for OpenVMS Product Manager
