Middleware Configuration; Host Failover; Multipath Failover - HP XP20000/XP24000 Configuration Manual

2 Middleware configuration

The disk array supports many industry-standard middleware products which provide host failover and
logical volume management. Available host failover products for the Novell NetWare server operating
system include the Novell High Availability Server (NHAS), SFT III software products, Novell Clustering
Services, and Novell Multipath Support.
Logical volume management functions are included in the Novell NetWare server operating system
(for example, Installation Option NetWare Loadable Module, NWAdmin).

Host failover

The NHAS and SFT III software products provide hardware fault tolerance (that is, host failover
capability) for the Novell NetWare environment.
Novell Clustering Service provides fault tolerance by moving (failing over) server resources from one
server to another.
If you plan to use these products with the disk array, contact your HP service representative for the
latest information about support and configuration requirements.
For assistance with NHAS or SFT III operations, see the Novell user documentation, or contact Novell
customer support.

Multipath failover

The XP disk arrays support NetWare multipath failover. If multiple FCAs are connected to the disk
array with commonly-shared LUNs, you can configure path failover to recognize each new device
path:
1. In the startup.cfg file, enter
SET MULTI-PATH SUPPORT=ON LOAD SCSIHD.CDM AEN
2.
If the line LOAD CPQSHD.CDM is present it should be commented out.
Example startup.cfg
SET MULTI-PATH SUPPORT=ON
LOAD ACPIDRV.PSM
######## End PSM Drivers ########
LOAD SCSIHD.CDM AEN
#LOAD CPQSHD.CDM
LOAD IDECD.CDM
######## End CDM Drivers ########
LOAD IDEATA.HAM SLOT=10011
LOAD CPQRAID.HAM SLOT=10019
LOAD QL2300.HAM SLOT=2 /LUNS /ALLPATHS /PORTNAMES/CONSOLE
LOAD QL2300.HAM SLOT=3 /LUNS /ALLPATHS /PORTNAMES /CONSOLE
######## End HAM Drivers ########
