Details of Change
The Fibre Channel Tachlite driver allows IPF (Itanium Processor Family) users running
HP-UX 11i v1.6 with the A6795A FC PCI 2 Gb adapter to connect to fabric using Fibre
Channel switches between the host and storage devices. The use of fabric enables better
performance, connectivity and fault isolation. Users can take advantage of the higher
link speed of the A6795A 2 Gb Fibre Channel HBA when used with 2 Gb capable
devices. The A6795A auto-negotiates 1Gb or 2Gb speed and can be used in the users’
existing 1Gb Storage Area Network (SAN) infrastructure.
The adapter is supported on the following IPF platform servers:
• rx4610
• rx9610
• rx5670
• rx2600
Fibre Channel boot and dump capabilities are available for the A6795A adapter on HP
rx5670 and rx2600 servers only. Fibre Channel boot and dump is not supported on
rx4610 and rx9610 servers.

migrating from HP-UX 11i v1.5 to v1.6, HP will replace your A5158A adapter with an
