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.

Supported servers

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:

http://h18006.www1.hp.com/products/sanworks/secure-path/index.html

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
