HP-UX 11i June 2001 Release Notes

General System Administration and Performance Monitoring

Changes to System Administration Manager (SAM)(updated for June 2001)

Chapter 7 143

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 (such as VxFS File System,

virtual memory, etc.) The subsystems are capable of recording

information at various levels ranging from simple status messages to

catastrophic failures. These logs can be read through SAM, either

from kernel memory or from a ﬁle on disk.

Network File Systems

• Support for NFS over TCP/IP. NFS supports exporting a ﬁle system

using the TCP/IP protocol. Accordingly, the Network File Systems

area in SAM has been enhanced to support this new NFS feature.

Now, the user can choose between TCP and UDP protocols to export

ﬁle systems.

Network Interface Cards

• Added support for Gigabit Ethernet card. The system administrator

can conﬁgure, modify the supported parameters, and also unconﬁgure

Gigabit Ethernet cards. This new SAM support is provided to both

1000Base-T and 1000Base-SX Gigabit Ethernet cards. This support is

also available on 10.20 and 11.0 through patches.

• Added support for 100-BaseT cards. The system administrator can

conﬁgure the 100-BaseT cards, modify any of the supported

parameters, and unconﬁgure the 100-BaseT cards. This support is

also available on 10.20 and 11.0 through patches.

• Added support for Independent Hardware Vendor (IHV). The system

administrator can conﬁgure network interface cards manufactured by

third party vendors that conform to the exported SAM Networking

interface. Users can conﬁgure, unconﬁgure and modify any of the

supported parameters of the card.
