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

• Introduces a mechanism to improve reliability for synchronizing cluster alias ID
sets among cluster members.
• Fixes the cause of the following CNX panic in cluster reconfiguration:
cnx_change_cluster_tx_state: illegal transaction state
• Fixes an ICS panic issue that occurs early in the boot process.
• Fixes a problem that causes the cluster alias manager SUITlet to falsely interpret
any cluster alias with virtual={t|f} configured as a virtual alias regardless of its
actual setting.
• Corrects problems in which SysMan drdmgr dumps tcl stack when a user tries to
manage devices or file systems of a cluster node that is down.
• Corrects an issue to allow the Device Request Dispatcher, DRD, to retry to get disk
attributes when EINPROGRESS is returned from the disk driver.
• Address issues with “address already in use” messages from klogin and kshell.
• Corrects a potential security vulnerability in CAA.
• Fixes a kernel memory fault.
• Corrects a problem in which the MC-API call imc_ckerrcnt_mr()incorrectly returns
an error status, although the functions error count parameter is not increasing.
• Preserves the error code from an asynchronous write error on a CFS client and
returns the error from the close() system call.
• Fixes a Distributed Lock Manager panic when calling the dlm_get_lkinfo() routine
passing an lkid of a lock block that has already been declared dead by the deadlock
detection thread.
• Corrects a problem to allow the use of 255 in the LAN Interconnect IP address.
• Fixes a CFS client panic during a file system read operation where the server goes
down. and the client itself becomes the server and attempts to release the direct
I/O token that had already been released.
• 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.
