HP Tru64 UNIX and TruCluster Server Version 5.1.B-4 Patch Summary and Release Notes (13156)

• Fixes a forced unmount of nonfailoverable file system (that is, NFS and AutoFS) panic in
the case that the initiator is down.
• Enables a cluster to boot even if the cluster root domain devices are private to different
cluster members. Although this is not a recommended configuration, it should not result in
an unbootable cluster. Currently, this is with respect to cluster root domains not under LSM
control.
• Corrects a potential data inconsistency caused by a problem in the CFS block reservation
code, which calculates incorrectly the amount of space requested and used by direct I/O
writes.
• Resolves a kernel memory fault in m_copym.
• Fixes a problem with the -b option of caa_report.
• Fixes a problem with caa_stop -f by allowing the administrator to reset a resource state from
UNKNOWN to OFFLINE even if the hosting member is down.
• 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.
• Fixes multiple disable or enable problems with cluamgr.
