The release notes in this section describe issues you may encounter and, when available, provide workarounds you can use.
Authentication Choice Affects sftp Transfer Rate |
 |
The performance of secure FTP (sftp) will be always less than ftp due to the authentication and encryption involved in sftp communication. The transfer rate of sftp depends on the type of authentication it employs. You can achieve better transfer rate performance by choosing the Message Authentication Code (MAC) algorithm hmac-md5 for authentication, but at the cost of security. The default MAC is hmac-sha1, which is more secure than hmac-md5. See sftp(1) for information about secure FTP and ssh2_config(4) for information about supported MACs and ciphers.
Tru64 UNIX Rebranding Results in File Changes |
|
As a consequence of the rebranding of Tru64 UNIX from the Compaq name to HP, the following files have changed:
version.abbrev_vendor from COMPAQ to HP
version.banner from Compaq Tru64 UNIX to HP Tru64 UNIX
version.vendor from Compaq Computer Corporation to Hewlett-Packard Company
The .mrg..sysconfigtab file has been modified to incorporate these changes into the generic sysconfig subsystem in the /etc/sysconfigtab file.
If the rebranding of HP Tru64 UNIX version information impacts any applications or layered products, you can manually change generic system version attributes. See the sysconfigtab(4) and sys_attrs_generic(5) reference pages for more information on how to modify generic system version attributes.
Insight Manager Components Dump Core |
|
Some Insight Manger components included in Tru64 UNIX Version 5.1B-4, such as cpq_mibs and the config_hmmod, and sysman_hmmod daemons, may core dump during reboots.
You can correct this problem by installing the latest version of the Insight Manager. At the time Version 5.1B-4 was released, the most current Insight Management Agents kit was Version 3.6. You can download this version from the HP Insight Management Agents for Tru64 UNIX Web site:
http://h30097.www3.hp.com/cma/
If you have not installed Version 3.6 or higher and the Insight Manager processes do not run after rebooting your system, restart them using the Insight Manger startup scripts.
Autoloader Firmware Upgrade Changes WWND |
|
A firmware upgrade to v1.50 or N14r on the 1x8 Autoloader causes the WWID to change. As a result, the existing device associated with the media changer is no longer accessible. For complete details see the Customer Advisory available at:
http://h30097.www3.hp.com/unix/erp/c00753663.html
Some Smart Array Errors May Not Be Recoverable |
|
When booting your system you may see a message similar to the following:
Smart Array at ciss(1) not responding - disabled. |
A system reboot may be able to re-enable the hardware. If that does not work, you need to call Field Service and have the unit repaired.
Do Not Use dxarchiver to Verify Bootable Tape |
|
Do not use dxarchiver command to verify a bootable tape. Instead, use the mt and restore commands as follows:
# mt fsf 1
# restore -i <device> |
The first command skips the first file on the tape.
When preparing for a btcreate session, verify the size of the file system to ensure that you have sufficient tape volumes, depending on the maximum storage capacity of your tape device. The btcreate command prompts you to load a new tape volume if it runs out of storage space. Label the tapes in sequence.
securenets File Requires localhost Entry |
|
If the /var/yp/securenets file is in use as part of NIS, it must contain the following localhost entry:
255.255.255.255 127.0.0.1 |
If the /var/yp/securenets file is used without a localhost entry you will see severe delays on logins. See ypserv(8) for more information.
