You must configure the Novell Storage Services (NSS) for
multipath support.
Perform the following steps to configure NSS for multipathing:
- Find and open the \NWSERVER\STARTUP.NCF file.
- Enable asynchronous event notification by finding the LOAD
SCSIHD.CDM line and adding AEN to the end of the line. The following
line provides an example for a line that enables asynchronous event
notification:
LOAD SCSIHD.CDM AEN
- Set multipathing support by adding the following line to
the top of the file:
SET MULTI-PATH SUPPORT=ON
- Configure the host bus adapters (HBAs) by performing the
following steps:
- Locate a line in the file that loads
a fibre-channel HBA (for example LOAD QL2300.HAM SLOT=101).
- Add the following parameters
to the end of the line, separated by spaces: /LUNS /MAXLUNS=## /ALLPATHS
/PORTNAMES. Use the following syntax:
LOAD adapter_driver_file.HAM SLOT=slot_number /LUNS
/MAXLUNS=max_number_luns /ALLPATHS
where adapter_driver_file is
the file name for the HBA driver, slot_number is the number
of the slot where the HBA is located, and max_number_luns is
the maximum number of logical unit numbers (LUNs) that are allowed
during the LUN scan. An example line is provided below:
LOAD QL2300.HAM SLOT=101 /LUNS /MAXLUNS=64 /ALLPATHS /PORTNAMES
- Repeat step 4.a and step 4.b for each
line in the file that loads a fibre-channel host bus adapter.
- Find and open the SYS:\SYSTEM\AUTOEXEC.NCF file.
- Insert the following line above the line that reads MOUNT
ALL:
