16 HP StorageWorks Auto Path for AIX: Installation Guide
Installation procedure
Configure the disk array LUNs to be accessible through at least one port in
each cluster of the array—one port in CL1 and the other in CL2.
Make the appropriate connections between the host HBAs and the disk
array ports.
Configure host bus adapters (HBAs) and switches. See the HBA product
documentation for the configuration method and settings. Verify that the
Fibre Channel connection method (such as Fabric or AL) matches the
settings.
The following setting must be made when using a Fibre Chennel switch
with AIX 5.1 and AIX 5.2 operating systems. Do this for each Fibre
Channel instance.
Example
chdev -l fscsiX -a fc_err_recover=fast_fail
Note Do this before creating hdisk device definitions. Failover times can take up
to 30 minutes if this setting is not made.
Important Auto Path will not install if the above steps for connecting to an XP array
are not completed and hdisk definitions representing XP LUNs are not
present on the system.
Install VisualAge C++ (version 5.0.0.0 or later) filesets on the host if
required. AIX 4.3.3 software may be obtained at:
