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

• Addresses a problem on LAN clusters related to improper keep-alive timeouts that can be
identified when the following console message is displayed during normal operations (that
is, no know failures and no nodes are rebooting):
— WARNING: ics_socket_event: error 60 on channel 0, assume node # is down
• Fixes a problem that occurs when the interconnect is configured using NetRAIN,
cluster_rebuild_delay is set significantly below the default value, and members are rebooting
or failures are occurring on the active links. The console message seen when this occurs is
“CNX QDISK: Yielding to foreign owner with provisional quorum.”
• Fixes a problem in which I/O barriers may be stalled when a drive becomes hung.
• Prevents write failures from a cluster NFS client that may occur when a second user without
write access is concurrently reading the file.
• Fixes a problem that occurs during reboots on heavily loaded cluster using the LAN
interconnect and generates the following messages:
— WARNING: ics_socket_event: error 54 on channel 0
— WARNING: ics_socket_event: error 60 on channel 0
• 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.
