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

• Fixes kmf in drd_kgs_bid_stop_server_io_drained when a node leaves during a
drd kgs transaction.
• Corrects a problem in which drd continually tries to perform a munsa unreject on
the drive when a device is deleted while it is in the munsa reject state.
• Corrects a problem in which multiple path failures cause drd to return ENODEV
even when a server is available in the cluster.
• Fixes several error handling in drd for device error conditions.
• Fixes problem in which a device cannot be opened due to heavy load on the device.
• Fixes a problem in which a CD-ROM is not mountable in a cluster.
• Fixes loss of quorum disk.
• Makes quorum disk parameters configurable.
• Eliminates a window for kernel memory fault panics on AdvFS system calls that
are performed via function shipping using the clu_msfs_syscall_fship routine.
• Improves drd tracing.
• Fixes a Sierra Cluster KCH set free race condition.
• Fixes two errors in clu_upgrade that prevents completing the setup stage.
• Prevents a get_cs_toks() KMF/assert crash.
• Fixes a rm_audit_sync_block panic that occurs when using a long fiber as the
Memory Channel interconnect.
• Fixes a timing window in the Internode Communications Subsystem ddr device
error handling.
• Fixes the rm_audit_sync_block panic when using a long fiber with VHUB as the
Memory Channel interconnect.
• Fixes clu_bdmgr to facilitate CLSM sliced disks for cluster_root domain.
• Modifies the manner of checking for user file limits for CFS remote DIO writes.
• Ensures that signals for EFBIG writes are properly generated on a client.
• Ensures the correct processing of CFS in future releases.
• Fixes a multiple free problem of 32-byte memory bucket caused by multiple
callbacks from KCH to CLUA.
• Fixes an incorrect if statement, which although a low- risk problem, could block
access to a disk device.
• Corrects a confusing error message.
• Fixes a problem seen in a LAN cluster when the CPUs on a member system are
not installed contiguously in the lower order slots.
• Allows the quorum disk to be used in spite of transient errors with the quorum
disk hardware.
• Corrects an internal logic error that causes the performance of file deletion to be
suboptimal.
• Fixes a deadlock that occurs when no members have valid paths to a device and
all the nodes in the cluster are attempting failover at the same time.
