Patch IDs Abstract

Patch 11.00

TCR150-012

Patch: Cluster Map Not Being Loaded At Boot Time Correction

State: Existing

Fixes a problem in TruCluster Available Server V1.5. The cluster map (/etc/CCM) was not being loaded at boot time, which prevented the Cluster Monitor utility (cmon) and its associated daemons (tractd and submon) from running.

Patch 13.00

TCR150DX-003

Patch: Cluster Monitor Hang Correction

State: Existing

Fixes a problem where if the name of an ASE service is changed using asemgr, any Cluster Monitor (cmon) that is running on the cluster will hang.

Patch 28.00

TCR150-031

Patch: ASE Check Service Script Could Be Corrupt

State: Existing

This patch corrects a problem in which an ASE check service script could become corrupted in the ASE configuration data base.

Patch 36.00

TCR150-025-1

Patch: dlm_panic Fix

Patch 46.00

TCR150-042

Patch: LSM Disk Not Updated in ASE Database

State: Supersedes patches TCR150-014 (12.00), TCR150-027 (25.00), TCR150-027A-1 (34.01), TCR150-035 (43.00)

  • Fixes a problem in which, under certain circumstances, an ASE service modification could result in a corrupted configuration data base.

  • Fixes a problem in which a service fails to start when the ASE service name and the AdvFS domain name are identical.

  • Fixes a problem where LSM disk information was not properly updated in the ASE database when volumes were removed from a disk service.

  • Fixes a deadlock condition between the DLM rebuild thread and the Connection Manager ping daemon (cnxpingd). The deadlock can cause users of DLM (e.g., Oracle) to hang.

Patch 47.00

TCR150-044

Patch: Kernel Memory Fault Panic

State: Existing

This patch fixes two panics:

  • A kernel memory fault with bss_rm_biodone() in the stack.

Patch 48.00

TCR150-045

Patch: Fix for AdvFS Panic

State: Supersedes patch TCR150-008 (7.00)

This patch corrects the following:

  • Fixes a problem in which running the vquotacheck command on a filesystem participating in an ASE service will cause a system to panic if the service fails over or relocates while the command is in progress.

  • Fixes a problem that could cause an AdvFS panic when a service that has quotas enabled is relocated. The problem occurs if a command is running that has a large number of arguments (>99).

Patch 49.00

TCR150-046

Patch: drdadmin Incorrectly Builds drdtab File

State: Supersedes patch TCR150-007 (6.00)

This patch fixes the following problems:

  • If a cluster member issued a drdadmin command to create new DRD map entry while another member is rebooting or had explicitly issued a SCSI bus reset, the command may fail with the following message:

    drdadmin: Error: Can not add map entry for drdadmin:
     Error: Can not add map entry for <drd device name>

  • During system startup, as each DRD map entry is being added. the following informational message may be seen on the console:

    No cluster has been setup, there are 0 nodes.

  • Fixes a problem where drdadmin does not properly build the drdtab file during bootup.

Patch 52.00

TCR150-050

Patch: Adding second cnxmond Causes Cluster Partition

State: Existing

This patch fixes a problem where starting a second cnxmond could cause a cluster partition. Attempting to start a second one will now log an error message, and the new process will exit.

  • Problem in which a resolver failure produces an unhelpful error message from mcm_init on boot.

  • Problem with the Memory Channel API whereby the function imc_ckerrcnt was signifying an error had occured when in fact no error had occurred. The following is the error code seen when running an MPI code:

    [5]MPI Die-ump2chck.c 91 "ump_wait failure" (-16)

State: Supersedes patches TCR150-004 (3.00), TCR150-030 (27.00), TCR150-036 (32.00)

This patch fixes the following problems in the ASE Availability Manager (AM):

  • A "simple_lock: time limit exceeded" panic on multiprocessor and system hangs in single processor systems. This can occur when multiple host target mode requests are issued due to SCSI aborts and resets on a shared bus.

  • A kernel memory fault panic caused by a race condition when the AM de-initializes.

  • Fixes a problem in which tape services may not failover as expected.

  • Fixes two problems:

    • A problem in which the following messages may appear in the binary error log:

      SCSI STATUS RESERVATION CONFLICT Target xx Lun xx

      or:

      Max SEND SCSI BUSY retries exhausted

    • A problem in which a system may panic if the system has an IDE interface and ASE is then installed.

  • Fixes a problem in the message service routines used by the daemons in TruCluster Available Server and TruCluster Production Server software. When the message queue fills, the following message is entered in the daemon.log file, but the queue is not emptied:

    msgSvc: message queue overflow, LOST MESSAGE!

    From this point on, no further messages will be received.

  • Fixes a problem in Version 1.5 of the TruCluster Production Server and TruClusterAvailable Server products where, during the start of a service, missing special device files were not being created for HSZ disks. Since the special device files did not get created, the service start would fail.

  • Fixes a segmentation fault that can cause ASE daemons to exit or hang.

  • Fixes a problem where the Host Status Monitor (asehsm) incorrectly reports a network down (HSM_NI_STATUS DOWN) if the counters for the network interface get zeroed.

  • Fixes a problem that caused the asedirector to core dump if asemgr processes were modifying services from more than one node in the cluster at the same time.

  • Fixes scalability problems in the DECsafe Available Server, TruCluster Available Server, and TruCluster Production Server products. The problems caused the asemgr to core dump when adding or modifying services with a large number of disks.

  • Fixes several problems related to ASE service relocation and reporting in the event of network failures.

  • Fixes a problem that could cause the ASE daemons or asemgr utility to core dump with a segmentation violation.

  • Fixes a problem in which under certain circumstances, an ASE service modification could result in a corrupted configuration data base.

  • Fixes several TCR problems involving large sites with services containing large numbers of DRDs.
