Important information This section provides important information about the 8/20q Fibre Channel Switch. • Optical transceivers. Only the HP 8 Gb Short Wave FC SFP+ (part number AJ718A) is supported for use in the HP StorageWorks 8/20q Fibre Channel Switch. • QuickTools stops responding after changing the switch's IP address. If you change the IP address of a switch when using QuickTools to access that switch, the QuickTools session at the old IP address stops responding. To access the switch with the new IP address using QuickTools, enter the new IP address in a new browser window. • Java must be enabled in the browser for QuickTools to launch. If Java support or Java scripting support is disabled in the browser, QuickTools will not launch. Ensure that Java support is enabled and/or Java scripting support is enabled. NOTE: The scripting support is called Enable JavaScript in most browsers and Active scripting or Active Web Content in Internet Explorer. • When running QuickTools, Java plug-in caching of temporary files and applets should be disabled. Java caching can cause the wrong version of QuickTools to run. When running QuickTools, Java plug-in caching of temporary files and applets should be disabled. If caching is enabled and a different version of QuickTools is loaded from a switch, the version of QuickTools previously run will load from the cache instead, but QuickTools could erroneously display the version number just loaded from the switch. However, be aware that if you have Java plug-in caching disabled and you upgrade your Java version, caching may become enabled and will have to be disabled again. • Information from some devices connected to a switch is not displayed by QuickTools. • Some connected device information displayed by clicking the information icon (i) in the Details column of the Devices Data Window (accessed by clicking the Devices tab) is shown as Undefined or Data Unavailable. This usually occurs because the information is not provided by the connected device. There are also some instances where the device model appears with the Vendor name. • Some connected device information displayed in the Vendor column of the Devices Data Window includes the device model with the Vendor name. • The connected device information in the Target/Initiator column of the Devices Data Window is displayed as Unknown for the MSA1000 and the MSA1500. • Call Home to HP Services is not supported at this time. Call Home to HP Services requires the 8/20q Fibre Channel Switch to communicate with the HP Open Service Event Manager (OSEM) application. The current version of OSEM (version 1.4.4) does not include support for the 8/20q Fibre channel Switch. Support will be available in the next release of OSEM. Known issues The following issues are corrected by the specified workarounds: • Issue: An EVA5000 or EVA3000 may not log in to the switch when you move the connection from one switch to another. If the connection to an EVA5000 or EVA3000 controller port is moved between two switches in the same fabric, hosts may not re-establish a connection to that controller port. Workaround: Using either QuickTools or the CLI, change the configured state of the switch port connected to the affected EVA controller to Offline and then re-enable this port by changing the configured state back to Online. This causes the EVA to successfully re-establish its connection with all zoned hosts. • Issue: HBAs may not successfully login to the switch following a reboot. Due to an occasional timing issue during port login negotiations, an HBA may not succeed in logging in to the switch. HP StorageWorks 8/20q Fibre Channel Switch release notes 5

Only the HP 8 Gb Short Wave FC SFP+ (part number AJ718A) is supported
for use in the HP StorageWorks 8/20q Fibre Channel Switch.
•
QuickTools stops responding after changing the switch’s IP address.
If you change the IP address
of a switch when using QuickTools to access that switch, the QuickTools session at the old IP
address stops responding. To access the switch with the new IP address using QuickTools, enter

•
Java must be enabled in the browser for QuickTools to launch.
If Java support or Java scripting
support is disabled in the browser, QuickTools will not launch. Ensure that Java support is
enabled and/or Java scripting support is enabled.
NOTE:
The scripting support is called
Enable JavaScript
in most browsers and
Active scripting
or
Active Web

disabled.
Java caching can cause the wrong version of QuickTools to run. When running
QuickTools, Java plug-in caching of temporary
fi
les and applets should be disabled. If caching is
enabled and a different version of QuickTools is loaded from a switch, the version of QuickTools
previously run will load from the cache instead, but QuickTools could erroneously display the
version number just loaded from the switch. However, be aware that if you have Java plug-in
caching disabled and you upgrade your Java version, caching may become enabled and will
have to be disabled again.
•
Information from some devices connected to a switch is not displayed by QuickTools.
•
Some connected device information displayed by clicking the information icon (
i
) in the
Details column of the Devices Data Window (accessed by clicking the Devices tab) is shown
as
Undefined
or
Data Unavailable
. This usually occurs because the information is not
provided by the connected device. There are also some instances where the device model
appears with the Vendor name.
•
Some connected device information displayed in the Vendor column of the Devices Data
Window includes the device model with the Vendor name.
•
The connected device information in the Target/Initiator column of the Devices Data Window
is displayed as
Unknown
for the MSA1000 and the MSA1500.
•
Call Home to HP Services is not supported at this time.
Call Home to HP Services requires the
8/20q Fibre Channel Switch to communicate with the HP Open Service Event Manager (OSEM)
application. The current version of OSEM (version 1.4.4) does not include support for the 8/20q
Fibre channel Switch. Support will be available in the next release of OSEM.
Known issues
The following issues are corrected by the speci
fi
ed workarounds:
•

moved between two switches in the same fabric, hosts may not re-establish a connection to
that controller port.
Workaround:
Using either QuickTools or the CLI, change the con
fi
gured state of the switch port
connected to the affected EVA controller to
Of

ine
and then re-enable this port by changing the
con
fi
gured state back to
