1.5 The Secure Path Software for Microsoft Windows NT
The Secure Path (v2.2) Software Kit for Microsoft Windows NT is comprised of the
following software components:
•
HszDisk.sys is a Windows NT class driver that works with StorageWorks RAID
Array controllers to enhance on-line storage availability and fault-tolerance. HszDisk
works in single-host and cluster environments to maintain optimum subsystem
performance during controller and storageset error recovery operations.
•
RaiDisk.sys is a Windows NT filter driver that provides support for multiple-bus
mode operation with StorageWorks RAID Arrays. RaiDisk performs automatic
failover of storagesets to the alternate path in the event of a primary path failure.
•
Secure Path Manager is the client application used to manage multiple-bus
StorageWorks RAID Array configurations. Secure Path Manager displays a graphical
representation of the current multiple-bus environment and indicates the location and
state of all configured storagesets on each of the paths. To facilitate static load
balancing, Secure Path Manager provides the capability to move storagesets between
paths. Secure Path Manager can be run locally at the managed servers, or remotely at
a management workstation.
•
Secure Path Agent is the server service that communicates with the RaiDisk filter
driver on the server and with the Secure Path Manager on the client side via TCP
WinSock interface. The Secure Path Agent makes use of Windows NT application
and event log and will post error and informational messages as required.
•
Secure Path Setup supports driver installation and uninstallation with Windows NT
4.0.
