Using the Emulex configuration tool

Miscellaneous Planning and Procedures
◆ EMC fabric with EMC PowerPath/ATF
(InitLinkFlags=0x00000002 (fabric, auto-link speed),
WaitReady=10, LinkDown=10)
ELXCFG.EXE v1.41a4 enables adapter settings to connect to a
Symmetrix, VNX series, or CLARiiON from the same host while
using the same adapter. This version is distributed separately, and is
labeled EMC universal configuration tool for Symmetrix, VNX
series, or CLARiiON. To enable custom EMC array configuration
settings, a user must start the utility with a command line option of --
emc. Refer to “Updating the shortcut” on page 203.
The EMC array auto-configuration settings are no longer presented
automatically as the configuration tool will no longer auto-detect if
an EMC array is present on the fabric. If the -- emc option is enabled,
the configuration tool will automatically mask some of the checkbox
selections, and will present a four-choice EMC array
auto-configuration dialog box under the Configuration-Set menu.
These settings noted below are modified for the global driver defaults
and apply to all adapters in the system. This enables the same
adapter to connect to a Symmetrix, VNX serie, or CLARiiON from the
same host while using the same adapter.
The EMC choices will reset the link-speed to Auto. Manually
modifying the link-speed later will no longer remove the checkbox
from the EMC auto-configuration choices.
All adapter global settings are Emulex defaults, with the exception of
the following:
◆ MaximumQueueDepth=32, MaximumLun=255,
UniqueNodeWwns=1,
ShowUnknowns=1, MultipleScsiClaims=1, BrokenRscn=1,
NameServerDelay=800ms, Windows Disk Class Driver
Timeout=60s
◆ EMC arbitrated loop without EMC PowerPath/ATF
(InitLinkFlags=0x00000000 (arbitrated loop, auto-link speed),
WaitReady=45, LinkDown=45)
◆ EMC arbitrated loop with EMC PowerPath/ATF
(InitLinkFlags=0x00000000 (arbitrated loop, auto-link speed),
WaitReady=10, LinkDown=10)
◆ EMC fabric without EMC PowerPath/ATF
(InitLinkFlags=0x00000002 (fabric, auto-link speed)
WaitReady=45, LinkDown=45)
