Fibre Channel Software Features
The Sun StorageTek Trac Manager software provides the following key features:
■
Dynamic Storage Discovery – The software automatically recognizes devices and any
modications made to device congurations. This feature makes devices available to the
system without requiring you to reboot or manually change information in conguration
les.
■
Persistent Device Naming – Devices that are congured within the software maintain their
device naming through reboots or reconguration. The only exception to this policy are
tape devices found in /dev/rmt that will not change unless they are removed, and then
regenerated at a later date.
■
Fibre Channel Arbitrated Loop (FCAL) Support – OpenBoot
TM
PROM (OBP) commands
that are used on servers can access FCAL attached storage for scanning the FC loop.
■
Fabric Booting – The Solaris OS supports booting from fabric devices as well as non-fabric
Fibre Channel devices. Fabric topologies with Fibre Channel switches provide higher speed,
more connections, and port isolation.
■
FC-HBA Library – What was previously known as the Storage Networking Industry
Association Fibre Channel host bus adapter (SNIA FC-HBA) library is now known as the
FC-HBA library. The FC-HBA library application programming interface (API) enables
management of FC HBAs and provides a standards-based interface for other applications
(such as Sun StorEdge
TM
Enterprise Storage Manager) that can be used to gather
information about FC HBAs.
Man pages for common FC-HBA APIs are included in the Solaris 10 OS in
libhbaapi(3LIB). For additional information about FC specications, refer to
http://www.t11.org.
SAS Software Features
■
Dynamic Storage Discovery – The Solaris OS Storage Multipathing software automatically
recognizes devices and any modications made to device congurations. This makes
devices available to the system without requiring you to reboot or manually change
information in conguration les.
