HP-UX 11i v3 Installation and Update Guide, March 2012

HP-UX 11i v3 device special files (DSF)
In a similar way to hardware paths, there are two types of Device Special Files (DSFs) for mass
storage: legacy DSFs and persistent DSFs. Both can be used to access a given mass storage device
independently, and can coexist on a given system.
DSFs: installing and updating
If you cold-install HP-UX 11i v3, both legacy and persistent DSFs are automatically created. By
default, the installation process will configure system devices like the boot, root, swap, and dump
devices to use persistent DSFs. This means that configuration files such as/etc/fstab, /etc/
lvmtab, and others will contain references to persistent DSFs.
When you update from HP-UX 11i v2 to 11i v3, existing legacy DSFs are retained and persistent
DSFs will be created. Configuration files are not updated to use agile DSFs. HP-UX will continue
to use the existing legacy DSFs referenced in configuration files.
Legacy DSFs are completely backward compatible, and will not be affected by any persistent DSFs
on the same server. A device can be simultaneously accessed via legacy and persistent DSFs.
For more information, including definitions of legacy and persistent, see “The Next Generation
Mass Storage Stack: HP-UX 11i v3” and “HP-UX 11i v3 Persistent DSF Migration Guide” (http://

HP Insight Remote Support Software
HP strongly recommends that you install HP Insight Remote Support software to complete the
installation or upgrade of your product and to enable enhanced delivery of your HP Warranty,
HP Care Pack Service or HP contractual support agreement. HP Insight Remote Support supplements
your monitoring, 24x7 to ensure maximum system availability by providing intelligent event
diagnosis, and automatic, secure submission of hardware event notifications to HP, which will
initiate a fast and accurate resolution, based on your product’s service level. Notifications may be
sent to your authorized HP Channel Partner for on-site service, if configured and available in your
country. The software is available in two variants:
• HP Insight Remote Support Standard: This software supports server and storage devices and
is optimized for environments with 1-50 servers. Ideal for customers who can benefit from
proactive notification, but do not need proactive service delivery and integration with a
management platform.
• HP Insight Remote Support Advanced: This software provides comprehensive remote monitoring
and proactive service support for nearly all HP servers, storage, network, and SAN
environments, plus selected non-HP servers that have a support obligation with HP. It is
integrated with HP Systems Insight Manager. A dedicated server is recommended to host both
HP Systems Insight Manager and HP Insight Remote Support Advanced.
Details for both versions are available at
