How to use the Novell Multi-path for IBM FAStT Storage Subsystems

Last Update: 08/08/2004

Instructions:

You must use Novell NetWare 6.0 with Support Pack 4 or higher.
The 'NetWare Failover' Host Type must be used for either the
default host type setting or the defined storage partitioning
host port settings.

Do not use the LSIMPE.CDM driver that is available from Support Pack if it
is older than the LSIMPE.CDM driver that is provided in this folder.

Download the following 3 files and place in c:\nwserver on the NetWare
server. 

a. Use the LSIMPE.CDM file provided in this package if it is newer than
   the one provided in the Netware OS installation CD and copy the 
   LSIMPE.CDM driverfile  to c:\nwserver directory in the Netware host.

b. Download the updated NWPA from http://support.novell.com : TID # 2966596
   and follow the installation instructions in the Novell TID. 

c. Download the newer MM.NLM from http://support.novell.com : TID#  2966389
   and follow the installation instructions in the Novell TID. 

Edit the STARTUP.NCF for the following:

a.  Add 'SET MULTI-PATH SUPPORT = ON'
b.  Add 'Load LSIMPE.CDM' before the SCSIHD.CDM driver
c.  Add the 'AEN' command line option to SCSIHD.CDM, expl: 'Load SCSIHD.CDM AEN'

Your STARTUP.NCF file should like somewhat like the following: 

SET Multi-path Support = ON
LOAD MPS14.PSM 
LOAD IDECD.CDM 
LOAD LSIMPE.CDM
LOAD SCSIHD.CDM AEN
LOAD IDEATA.HAM PORT=1F0 INT=E 
LOAD ADPT160M.HAM SLOT=10010 
LOAD ADPT160M.HAM SLOT=10011
LOAD QL2300.HAM SLOT=4 /LUNS /allpaths /portnames /xretry=400
LOAD QL2300.HAM SLOT=5 /LUNS /allpaths /portnames /xretry=400


Disable all other multi-path support. For example, when using QLogic adapters,
load the driver with '/luns /allpaths /portnames'. The 'allpaths' option disables
the QLogic failover support.

Startup the server.

If your configuration is correct you will not need to set the failover priorities for your
LUNs, the LSIMPE.CDM driver will configure these.  

Use the multi-path documentation to verify the failover devices.
