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

For more information about the custom_gated option, see the revised cluamgr(8)
reference page included in this kit.
3.2.1.32 fsdb Utility Now Operates on File System Image
The fsdb utility is now capable of operating on a file system image as well as a special
file. The name argument will first be processed as a special file; should that fail, it will
be processed as a regular file. To avoid conflict, an optional f argument will force the
name argument to be processed only as a regular file. See the revised fsdb(8) reference
page delivered in this kit.
3.2.1.33 sendmail Log Problem Corrected
This kit corrects a problem with sendmail registration as a PSM (Process Set Manager)
process. EVM would incorrectly log the following statements when sendmail was
stopped or started or restarted:
PSM instance pid exited in category _unknown_ on node nodename PSM
instance pid created in category _unknown_ on node nodename
Where pid is the process ID of the sendmail daemon and nodename is the host where
sendmail runs.
The sendmail program now correctly registers itself with the PSM and the same is
reflected in log records.
3.2.1.34 New Tunable Attribute Corrects NetRAIN Failover Problem
A new tunable attribute fixes a NetRAIN failover problem that occurs in a “quiet”
network. In a two interface NetRAIN set, if the current active interface goes down, the
secondary (backup) interface fails to become the new primary (active) interface. To
correct this problem, set the new nr_use_link_state attribute as follows:
# sysconfig -r netrain nr_use_link_state=1
For information about this attribute, see the revised sys_attrs_netrain(5) reference page
delivered in this kit.
3.2.1.35 New Attribute Controls Tape Driver Path Control
A new cam tape subsystem attribute, enable_preferred_path, lets you control
preferred path behavior for a tape driver. Enabling this attribute (1) causes the tape
driver to assign different paths to different tape drives. The default (0) disables preferred
path behavior. The revised sys_attrs_cam(5) reference page delivered in this kit describes
the enable_preferred_path attribute.
A problem may exist when using preferred path behavior when you use a no-rewind
tape device. If the application is not expecting the tape to change position between a
previous tape close and a subsequent tape open, the data already on the tape may be
lost with the next write command, possibly resulting in unusable backups. This problem
only occurs when a system has multiple initiators.
