HP Tru64 UNIX Technical Updates for the Version 5.1B and Higher Operating System and Patches (February 2010)

Operating System and Associated Products Updates
Netscape Browser No Longer Supported (May 2007)
The Netscape Web browser is no longer supported on Tru64 UNIX and updates to it are no
longer available on the Tru64 UNIX Web site.
Because of potential security threats with the Netscape browser on Tru64 UNIX, HP recommends
that you download the latest Firefox browser for Tru64 UNIX. You can find that browser at the
following site:
http://h30097.www3.hp.com/internet/download.htm
If you install or reinstall Tru64 UNIX from the operating system CD that ships in the Tru64 UNIX
kit, HP recommends that you not install the included Netscape browser, but instead install the
Firefox browser and make that your default browser.
live_dump() Function May Not Collect All Dumps (May 2007)
Under certain circumstances the live_dump function is unable to collect dumps, even if the
AdvfsDomainPanicLevel attribute is set to 1 (mounted) or 2 (mounted or unmounted). For
example, live dumps will not be collected when the process is at the input/output completion
path.
Help Files Missing from the AdvFS Management GUI (Oct. 2006)
Some online help files are missing in two locations from the SysMan Advanced File System
(AdvFS) graphical interface. The missing help screens are apparent when you are managing
volumes and want to modify the size of a partition. The following locations are affected:
• The Managing Volumes window provides an Expand button that displays a pop-up dialog
where you enter a value for the partition size. The pop-up dialog provides a help button.
However, no online help is associated with this button.
• After you modify the partition size and press the Next button, a confirmation dialog is
displayed. If you press the Help button in this dialog, the following message is displayed:
Non existent location ID: WExpandPartConfirm
No help volume is available for this dialog.
For information on the partition size options available when modifying volume partitions see
AdvFS Administration.
Applications Using SCSI_GET_INQUIRY_DATA Must Initialize Field (May 2005)
Applications that use the SCSI device SCSI_GET_INQUIRY_DATA ioctl must fully initialize the
structures used in that ioctl. This change causes the previously defined ms_pgcode field (defined
to contain the requested page code value) to be initialized for the page code. Prior to this change,
that field was ignored, therefore applications that did not initialize that field may now see a
possible change in their function.
Recommend Setting for DRD Parameter when Running LSM voltrace Command (May
2005)
When using the LSM voltrace debugging utility in a cluster, it is recommended that the DRD
system configuration parameter, drd_nolwc, be set to 1 to prevent a possible assert_wait
panic.
Performance enhancements in DRD changed behavior such that DRD may have blocked the
thread corresponding to an I/O request that LSM now needs to block as part of voltrace
processing. Turning on drd_nolwc will avoid this issue. It should be turned off after voltrace
runs as it will affect overall I/O performance.
