Changes to System Administration Manager (SAM)
The /usr/sbin/sam command starts a menu-driven System Administration Manager
(SAM) program that makes it easy to perform system administration tasks with only
limited, specialized knowledge of the HP-UX operating system.
SAM has been enhanced to support new devices and features in the following areas
within its interface: Disks and File Systems, Kernel Configuration, Network File
Systems and Interface Cards, Peripheral Devices, Printers and Plotters, and Terminals
and Modems. HP-UX and SAM discontinued support of NFS Diskless as of HP-UX 11.0.

new at 11i
original release

larger volumes of mass storage. This support was also added in a patch to 10.20 and
11.0.
• Added support for the HP SureStore Disk Array XP256. This allows you to manage
larger volumes of mass storage (up to 11 Terabytes). This support was also added in
a patch to 10.20 and 11.0.
• Added recognition of disks being used by HP VERITAS Volume Manager (VxVM)
and their associated Disk Groups and Volumes. You can launch the HP VERITAS
Manager Storage Administrator (vmsa) tool from within the SAM Disks and File
Systems area.
Kernel Configuration
• Added support for dynamic tunables. These changes allow a user to tune dynamic
tunables using SAM and have the values take effect immediately. The user will see
differences in modifying tunable parameters and in applying tuned parameter sets.
When modifying a tunable, the value/formula selected by the user will take effect
immediately if the tunable is dynamic. In applying tuned sets, the entire tuned set
will take effect immediately if every tunable in the set is dynamic. Otherwise, the
tuned set won't take effect until the kernel is rebuilt and the system is rebooted.
• Added support for kernel logging. Kernel logging is a new feature for 11i. Through
SAM, system administrators will be allowed to modify options associated with this
feature, such as turning logging ON and OFF, for many of the kernel subsystems
