HP Tru64 UNIX and TruCluster Server Version 5.1B-6 Patch Summary and Release Notes

LSM hot-sparing Improved
The Logical Storage Manager (LSM) command volwatch has been enhanced to improve LSM
hot-sparing, which pro-actively replaces plexes that are based on failing storage devices and
recovers their data.
Now when hot-sparing is performing a recovery, it will avoid using a plex that it is relocating
— unless it has no other choice.
New Option Changes Configuration File Used by aliasd Daemon
A new option, custom_gated, has been added to the cluamgr command to change the
configuration file used by the aliasd daemon.
You can cause aliasd to use the file /etc/gated.conf instead of /etc/
gated.conf.memberX as the gated configuration file and restart gated in either of the
following ways:
• Specify the cluamgr command as follows:
# cluamgr -r gated,custom_gated,start
• Modify the /etc/rc.config.common file by specifying the following command:
# rcmgr -c set CLUAMGR_ROUTE_ARGS "gated,custom_gated"
After running the rcmgr -c command, restart network services by running the rcinet
command on all cluster nodes:
# rcinet restart
For more information about the custom_gated option, see the revised cluamgr(8) reference
page included in this kit.
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.
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.
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.
