Switch support
This release supports the Fibre Channel (FC) switches and firmware versions listed in the HP StorageWorks
SAN design reference guide, which you can download from the HP StorageWorks web site:
http://h18004.www1.hp.com/products/storageworks/san/documentation.html
NOTE:
HP recommends that you
not mix switch firmware versions in a SAN. It is a best practice to uniformly
upgrade all switches in the SAN.
Multiple-path support
For an HP-UX system with EVA4000/6000/8000 storage HP recommends the installation of
multipathing software on each host to achieve high-availability, multipath capability.
HP-UX pvLinks native multipathing solutions are supported. For more information about pvLinks, see your
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.

For information about operating constraints for the EVA4000/6000/8000 hardware and HP
StorageWorks Command View EVA, see their release notes.
Failover/failback
Failback preference settings for the 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.
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 multipathing
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, run
vgchgid(1M) to break the association between the volume group and the snapshot or snapclone.
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 added later 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 controller failure, path
link failure, switch failure, or HBA failure, 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 is 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 are
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 under
heavy I/O loads. 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. 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 utility
Use the following command to access SSSU:
# gsssu
In the command text box, enter an SSSU command. For example:
select manager ip_address username=username password=password
