Product details and specifications

The optional Node and Host Name Expansion product bundle (NodeHostNameXpnd, revision B.11.23.01) contains a product (NodeHostXpndEnbl, revision B.11.23.01) which allows the system administrator to set expanded node and host names.

Without this product, node names may be up to 8 bytes and host names up to 64 bytes.�With the product, they may be up to 255 bytes each.

This version of the product is intended for customers who have formally contacted HPE about their need for longer node and host names.

Features and Benefits

Node and Host Name Expansion provides the following features and benefits:

  • Allows more meaningful node and host names
  • Provides flexibility for system expansion
  • Provides compatibility with future application software


Using long node and host names may affect the operation of other system or application software. Install the NodeHostNameXpnd product bundle only if you intend to actually use expanded node and/or host names, or intend to develop software which accommodates expanded names. See the document Node and Host Name Sizes on HP-UX for instructions on how to activate the extensions and a description of application compatibility issues before installing this bundle. This document should be read and understood before using the product. It is available after installation at usr/share/doc/NodeHostNameSize.pdf.

The SNAplus2 product was not updated to accommodate expanded node and host names at the time this document was written. If you utilize this product, setting expanded node and/or host names will result in system errors. DO NOT install the optional long node and host name feature on systems using the SNAplus2 product until the long node and host name feature is supported. Check the HPE IT Resource Center for the latest information.

Required patches /Updates for Optional Products

The NodeHostNameXpnd product bundle contains all base operating system patches required for handling expanded names (except as noted in this section). Updates and patches for optional HPE products to handle expanded names are listed in the table below. These product updates and patches are not contained in the NodeHostNameXpnd product bundle.

The base operating system patches PHCO_31926 (SAM) and PHSS_32674 (ObAM) need to be installed to support expanded host names longer than 64 bytes. They are not included in this version of the NodeHostNameXpndbundle and are not automatically installed. Setting a longer host name and using SAM without these or superseding patches will result in errors or runtime aborts.

The following table contains the update/patch versions required for optional HPE Products supporting expanded node and host names. Earlier versions of these products may exhibit anomalous behavior or failures when used on a system configured with long node and/or host names.

Known Problems

Any application which uses node and/or host names and has not been enhanced to handle expanded names longer than 8 and 64 bytes, respectively, may exhibit anomalous behavior or fail when longer names are used. Additional information on the use of this product including functional limitations is detailed in Node and Host Name Sizes on HP-UX. HPE strongly recommends that this paper be well understood before enabling this product. For the latest information, check your nearest HPE Support Center:
