6. Tech Tips

Issue During Intel’s extended stress test runs, fibre channel hard drives attached to the

Emulex* LP1050Ex or Qlogic QLE2360 PCI Express fibre channel adapters begin

experiencing delayed write failures and were eventually marked offline. These

failures have only been seen when running under Microsoft* Windows* Server

2003. Failures have not been seen when running under Novell* Netware* 6.5 or

Red Hat* Advanced Server 3.0.

Implication Fibre channel hard drives may experience delayed write failures or the hard drives

may be marked offline if the Emulex* LP1050Ex or Qlogic QLE2360 PCI Express

fibre channel adapters are utilized in combination with Intel® Server Board

SE7320SP2, SE7520BD2, SE7520AF2, SE7520JR2, or SE7320VP2 and the

Microsoft* Windows* Server 2003 operating system, if the system is subjected to

extended periods of intensive I/O application stress.

Guideline The Emulex* LP1050E or Qlogic QLE2360 PCI Express fibre channel adapters

should not be utilized with the Intel® Server Board SE7320SP2, SE7520BD2,

SE7520AF2, SE7520JR2, or SE7320VP2 with the Microsoft* Windows* Server

2003 operating system. The Emulex LP1050Ex or Qlogic QLE236x PCI Express

fibre channel adpateres may be used with therse server boards with Novell*

Netware* 6.5 or Red Hat* Advanced Server 3.0.

Status Intel is currently working with Emulex and Qlogic to investigate a fix for this issue.

Problem The Emulex* LP9802DC PCI-X fibre channel host adpater works as expected

when in Intel® Server Board on Microsoft Windows* and supported Linux

configurations. However, when the adapter is installed in an Intel system with

Netware 6.5, the driver is not recognized by Netware. Netware fails to recognize

both driver versions 2.00c and 2.02g. The likely source for this failure is a conflict

between the Netware operating system and the PCI-X bridge chip that is used on

the LP9802DC adapter.

Implication The Emulex* LP9802DC-F2 adapter driver is not recognized by Novell Netware*

6.5.

Guideline The Emulex* LP10000DC adpater is a compatible, next generation bridgeless

solution, which offers the same feature set with increased performance, work as

expected under Novell Netware 6.5 and has been validated as a supported

adapter on current Intel® platforms

Status Intel is currently working with Emulex to investigate a fix for this issue.
