HP Tru64 UNIX and TruCluster Server Version 5.1B-5 Patch Summary and Release Notes (March 2009)

• AdvFS monitoring capability. (See “Enhancements to pmgrd Daemon and collect
Utility” for a list of AdvFS metrics that are monitored.)
Enables collect to report AdvFS volume I/O queue and fileset vnode operation
statistics. You can specify the domain or fileset to be monitored, using the -A option.
• Viewing CPU and memory metrics on a per Resource Affinity Domain (RAD)
basis.
When run on a NUMA platform, enables collect to automatically retrieve CPU
and memory metrics for each RAD.
See collect(8) for more details.
3.2.1.47 File System Management Applications Enhanced
Enhancements to the SysMan Menu file system management applications delivered
in this patch kit significantly improve their performance.
3.2.1.48 New Control Option for /usr/sbin/audit_tool Command
This kit provides the following new control option for the /usr/sbin/audit_tool
command:
# /usr/sbin/audit_tool -. [path]
This option causes audit_tool to use [path] for the archive/recovery directory
that contains archived audit logs, thereby overriding the directory specified in the audit
log, which by default is /var/audit.
3.2.1.49 Change to envmond Improves Performance on Some Systems
This patch kit modifies the Environmental Monitoring daemon, envmond, to improve
performance on systems with many sensors.
With the default monitor period of envmond (ENVMON_MONITOR_PERIOD), systems
having large number of sensors may experience a performance degradation. The changes
to envmond address this problem by polling sensors at a lower frequency.
3.2.2 Release Notes Introduced in Prior Kits
The release notes in this section were included in previous patch kits.
3.2.2.1 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.
