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

• Corrects a potential data inconsistency that may occur when a domain is nearly
full. Client write requests shipped synchronously to the server will no longer have
subsets of pages written asynchronously due to a race with virtual memory.
• Improves the scaling of IP reassembly code on large SMP machines. NFS servers
are especially susceptible when a large number of clients attempt to write at the
same time.
• Helps to close a race where synchronous writes may obtain disk allocations that
were promised to cached client writes.
• Fixes a problem in which CAA might prevent alias based services from properly
functioning by binding to one the cluster alias reserved ports.
• Corrects a problem in a Memory Channel cluster where rebooting a node without
performing a hardware reset can crash other members with a
RM_AUDIT_ACK_BLOCK panic.
• Fixes a problem in the Memory Channel driver.
• Improves the responsiveness of EINPROGRESS handling during the issuing of
I/O barriers by removing a possible infinite loop scenario that could occur due to
the deletion of a storage device.
• Fixes a problem that causes a panic with the message "CNX MGR: Invalid
configuration for cluster seq disk" during simultaneous booting of cluster nodes.
• Fixes the panic "CNX MGR: Invalid configuration for cluster seq disk" that occurs
during the simultaneous booting of cluster nodes.
• Fixes a possible race condition between a SCSI reservation conflict and an I/O drain
that can result in a hang.
• Alleviates a condition in which a cluster member takes an extremely long time to
boot when using LSM.
• Fixes a problem that caa_relocate AutoFS does not kill the autofsd daemon.
• Allows rewrites when the domain is close to out of space.
• Ensures correct processing in the close() system call.
• Provides a CAA action script that can be used by a NIS Slave running to help
assign a crontab entry to update NIS maps.
• Fixes a problem in which a cluster member leaves the cluster alias yet continues
to respond to it.
• Corrects a problem that causes applications (including cluamgr) to get a dummy
cluster alias reported from the cluaioc_get_nextalias() call. The IP address for this
alias is 0.0.0.0.
• Fixes a problem in which aliasd creates multiple similar virtual subnet static routes
in the gated.conf.memberX, thereby causing gated to fail to load.
• Fixes issues associated with the initialization of the Memory Channel driver.
• Provides a function to query the status of aliasd.
• Fixes an IPv6 bind problem in a cluster environment.
