HP StorageWorks Secure Path V2.0D Service Pack 2 for IBM AIX Release Notes (T3034-98201, May 2004)

Operating considerations
11Secure Path v2.0D Service Pack 2 for IBM AIX Release Notes
hdisk3 Available 20-58-00-0,3 HP HSG80 RAID Array
hdisk4 Available 20-58-00-0,4 HP HSG80 RAID Array
hdisk5 Available 20-58-00-0,5 HP HSG80 RAID Array
hdisk6 Available 20-58-00-0,1 HP HSG80 RAID Array
hdisk7 Available 20-58-00-0,2 HP HSG80 RAID Array
In the previous example, note that the output HP HSG80 RAID Array hdisks are
all assigned to one of the two Cambex Fibre Channel I/O Controllers for the
Secure Path configuration. This occurs during configuration and it is determined
by the sequence in which the devices are found and defined. The sequence is
irrelevant to Secure Path as the driver automatically switches I/O to the alternate
path if an active path fails.
Controller software upgrades
HSGx0
You can upgrade the RAID Storage Subsystem controller software (ACS) Version
8.6 to Version 8.7 without terminating I/O. This procedure is known as a Rolling
Upgrade. Refer to the HP StorageWorks HSG80 Array Controller V8.7
Maintenance and Service Guide for detailed information about Rolling Upgrades.
HSVx
When upgrading EVA VCS firmware, both controllers become inoperative.
Secure Path for IBM AIX cannot handle this condition. You must stop all
operations to an EVA storage unit prior to upgrading the HSVx software.
Managing Secure Path v2.0D Service Pack 2 using smit
The Secure Path management tools have been integrated into the IBM AIX smit
utility. From the smit menus, many different functions can be performed such as:
■ Monitoring failover
■ Configuring failback
■ Resolving failures
Note: HP is currently working on the issue of rolling upgrades on EVAs. The resolution
will be available in a future Secure Path for IBM AIX release.
