Troubleshooting

Known issues

Be aware of these issues:

◆ NTOSKNL BSOD (blue screen) during a link down event can

cause file system corruption to mounted file systems.

◆ Adapter boot BIOS does not support high availability. A boot

attempt during a simultaneous path failure will fail. On VNX

series or CLARiiON systems, it also will fail after failure of a path

that requires a trespass of the boot LUN. Manual intervention is

required to trespass the LUN to the other SP and boot from it.

◆ Degraded response time as the I/O load approaches storage

system capacity can make the OS appear hung or result in a

NTOSKNL BSOD.

◆ Boot files, Windows system files, and swap space should all be on

the boot LUN. With certain server models, you can use an internal

disk for the page file for stability; however, this may not increase

fault tolerance and might reduce system recovery options.

◆ Swap space must be available on %SYSTEMROOT% or core

dump will fail.

◆ You can configure any supported adapter for the boot LUN.

Higher model-number adapters will appear first in the boot BIOS

displays.

◆ Windows 2000 hosts running less than SP4 could be susceptible to

data loss during LUN expansion operations. This issue is

corrected by Microsoft in SP4, or by applying hotfix 327020. Refer

to EMC Solution IS emc73538 and Microsoft Knowledge Base

article 327020 for more information.

◆ For Windows 2003 on 64-bit IA64-2 servers, the system no longer

uses an x86-compatible BIOS; therefore, enabling boot-from-array

support with the adapter requires a separate firmware EFI

download.

◆ If using STORPort drivers, you are required to use minimum

Microsoft QFE 891793 if you wish to move the page file from the

default boot disk to a local disk. You must install the QFE and

reboot prior to moving the page file or the server will potentially

generate a NTOSKNL BSOD crash. (This is not required on

Windows 2003 for X64.)

◆ In configurations where the Emulex LP8000 is connected to

storage using Cisco MDS switches, the switch port for the LP8000

is required to be hard-set to 1Gb speed.
