NPAR
Problem
: The following error message appears if the storage configurations are
not consistent for all four ports of the device in NPAR mode:
PXE-M1234: NPAR block contains invalid configuration during boot.
A software defect can cause the system to be unable to BFS boot to an iSCSI or
FCoE target if an iSCSI personality is enabled on the first partition of one port,
whereas an FCoE personality is enabled on the first partition of another port. The
MBA driver performs a check for this configuration and prompts the user when it is
found.
Solution
: If using the 7.6.x firmware and driver, to workaround this error,
configure the NPAR block such that if iSCSI or FCoE is enabled on the first
partition, the same must be enabled on all partitions of all four ports of that device.
Miscellaneous
Problem
: iSCSI Crash Dump is not working in Windows.
Solution
: After upgrading the device drivers using the installer, the iSCSI crash
dump driver is also upgraded, and
iSCSI Crash Dump
must be re-enabled from
the
Advanced
section of the QCS
Configuration
tab.
Problem
: In Windows Server 2008 R2, if the OS is running as an iSCSI boot OS,
the VolMgr error, “The system could not successfully load the crash dump driver,”
appears in the event log.
Solution
: Enable
iSCSI Crash Dump
from the Advanced section of the QCS
Configuration
tab.
Problem
: The QLogic 8400/3400 Series adapters may not perform at optimal
level on some systems if it is added after the system has booted.
Solution
: The system BIOS in some systems does not set the cache line size and
the latency timer if the adapter is added after the system has booted. Reboot the
system after the adapter has been added.
Problem
: Cannot configure Resource Reservations in QCS after SNP is
uninstalled.
Solution
: Reinstall SNP. Prior to uninstalling SNP from the system, ensure that
NDIS is enabled using the checkbox on the Resource Configuration screen,
available from the Resource Reservations section of the Configurations tab (see
“Viewing Resource Reservations” on page 126
). If NDIS is disabled and SNP is
removed, there is no access to re-enable the device.
Problem
: A DCOM error message (event ID 10016) appears in the System Even
Log during the installation of the QLogic adapter drivers.
Solution
: This is a Microsoft issue. For more information, see Microsoft
