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

• Corrects a problem in which volmigrate returns a shell error when attempting to migrate
an AdvFS domain with multiple filesets. These domains can now be migrated as long as all
the filesets are mounted.
• Prevents inconsistent LSM volumes when the name of a partition that is being encapsulated
matches the name of a current LSM volume.
• Corrects a problem in which smsd triggers LSM configuration errors when querying LSM
in a cluster. This fix ensures that a cluster member will be up to date with respect to the LSM
configuration when calls are made to an internal LSM routine.
• Corrects a problem during the creation of a new plex in which the volmake command reports
that associating a subdisk with the plex would cause an overlap with another subdisk when
they should not be overlapping.
• Prevents vold from core dumping when attempting to delete a disk that was not initialized
properly.
• Provides protection against a class of potential security vulnerabilities called buffer overflows.
Buffer overflows are sometimes exploited in an attempt to subvert the function of a privileged
program and possibly execute commands at the elevated privileges if the program file has
the setuid privilege. This patch allows a system administrator to enable memory management
protections that limit potential buffer overflow vulnerabilities.
• Corrects an I/O performance issue that occurs when CLSM is configured and one member
of a cluster goes down unexpectedly.
• Fixes a slow boot when booting several cluster nodes at the same time and CLSM is
configured.
• Enables volassist to create a mirror of a striped volume with the mirror having a layout of
concat.
• Corrects an error return code for volinfo. If a specified volume is not in the configuration
database, the error code returned from volinfo will reflect this error.
• Corrects an issue of a cluster node hanging during a boot while another member recovers
the cluster root file systems.
• Allow volsave and volrestore to save nconfig/nlog policies for disk groups and restore them
appropriately.
• Corrects awk errors for invalid quit statements.
• Corrects a problem in which lsmbstartup does not ignore comment lines in /etc/fstab, thereby
making it possible for it to attempt to process that line if it appears to be an entry for the
root file system.
• Corrects an internationalization problem in which an instructional message that is output
by the LSM voldiskadm command's list option is incorrect because it had not been entered
properly in the message catalog.
• Improves null partition checking code.
• Modifies the volassist command to correctly output a warning message for its shrink
operations.
• Enables a full recovery to occur in the event of an invalid magic number found in the recovery
map.
• Corrects a problem in which the volplex command does not send a disk group option to the
usage type utility when both the usage type and disk group options are specified on the
command line.
• Allows a mirrored swap plex to be detached when it contains a phantom subdisk.
• Corrects a problem in which vold may dump core when connectivity to a disk group is lost,
for example its underlying storage is local to one cluster member and that cluster member
leaves the cluster.
• Modifies volsave and volrestore to let them handle public and private offsets of an LSM
disk.
