Switch support
This release supports the Fibre Channel switches and firmware versions listed in the HP StorageWorks
SAN design reference guide, available on the following web site:
http://h18004.www1.hp.com/products/storageworks/san/documentation.html
NOTE:
HP recommends that you
not mixswitchfirmwareversionsinaSAN.Itisabestpracticetouniformly
upgrade all switches in the SAN.
Multiple-path support
HP-UX with EVA storage requires the installation of multipathing software on each host to achieve
high-availability, multiple-path capability.
Native multipathing functionality is now available. Secure Path for HP-UX is no longer required.
You can choose HP-UX pvLinks native multipathing solutions. For more information about pvLinks,
see the HP-UX operating system documentation.

Single-path support
HP-UX servers require a single Fibre Channel adapter (FCA) to support single-path mode.
NOTE:
Do not use single-path mode in mission-critical environments.

Operating constraints
For information about operating constraints for the EVA and HP StorageWorks Command View EVA, see
their respective release notes.
Failover/failback
Failback preference settings for the Hierarchical Storage Virtual (HSV) controllers are specific to
the operating system. See the HP StorageWorks HP-UX connectivity for the Enterprise Virtual Array
installation and reference guide for more information.
Storage System Scripting Utility for EVA
The latest version of the Storage System Scripting Utility (SSSU) is available on the HP storage web site:
http://h18006.www1.hp.com/products/storage/software/cmdvieweva/index.html
Recommendations
This section contains HP recommendations to ensure proper operation of the EVA4000/6000/8000
storage system.
Secure Path version
Secure Path is an optional EVA4000/6000/8000 multipathing solution. The current version of Secure
Path for HP-UX is available on the following web site:

Codeload usage
When a system with a maximum configuration is running at full capacity, it may experience a time-out
condition before codeload is complete. HP recommends that you always upgrade the controller
software at an off-peak time.
Logical Volume Manager
Before creating snapshots or snapclones of a device managed by Logical Volume Manager (LVM), be
sure to verify the LVM configuration. After creating a snapshot or snapclone of a physical volume,
always run vgchgid(1M) to break the association between the volume group and the snapshot or
clone. Otherwise, snapshots or snapclones appear to LVM as an alternate path to the original physical
volume. This causes data corruption if the snapshot or snapclone is later added to the volume group
using vgextent(1M),vgimport(1M),orvgscan(1M).
When a path to a device managed by LVM becomes unavailable because of a failed controller, path
link, switch, or HBA, I/O requests can be delayed for up to one minute, affecting the responsiveness
of mirrored logical volumes.
When a physical volume becomes unavailable, applications experience a delay while an I/O request to
that volume times out. By default, this delay takes 30 seconds, but you can change the time-out value
using the pvchange(1M) command.
Overloaded EVA configurations
Persistent EVA overload may indicate an overloaded configuration, and additional resources may be
required to handle the workload. Consult your HP account or service representative for help to properly
configure the EVA for your newly designed or existing configuration.
High-availability environment recommendations
If you have a high-availability environment, your system may experience I/O time-out conditions. If I/O
time-outs occur, HP recommends that you use the pvchange command to increase the IO_timeout
value from the default of 30 seconds to no more than 60 seconds. Under heavy I/O load conditions,
the increased IO_timeout value allows for longer I/O completion times and for logical unit number
(LUN) access delays if a controller failover occurs.
NOTE:
Ensure that you have HP ServiceGuard configured properly. More information is available on the
ServiceGuard web site: http://docs.hp.com/hpux/ha/index.html#ServiceGuard.
gsssu command
Use the following command to access the SSSU:
# gsssu
In the command text box, enter the SSSU command you want to perform. For example:
select manager ip_address username=username password=password
