SUMMARY OF KNOWN ISSUES: ----------------------------------------- NONE KNOWN ISSUES : -------------- NONE FIXED INCIDENTS: ---------------- PATCH ID:VRTSamf-6.0.500.000 * INCIDENT NO:3140962 TRACKING ID:3140961 SYMPTOM: The Asynchronous Monitoring Framework (AMF) driver panics the system when a Veritas File System (VxFS) file system is mounted or unmounted. DESCRIPTION: Sometimes AMF fails to a handle a condition when the system makes a mount or unmounts call for the VxFS file system. Concurrently, the AMF notifies a state change for the last registered VxFS resource causing a system panic. RESOLUTION: The code is modified to enable AMF driver to handle conditions while the system makes a mount or unmounts call. * INCIDENT NO:3145057 TRACKING ID:3145047 SYMPTOM: The Asynchronous Monitoring Framework (AMF) driver causes a panic in the machine after VXFS driver is unloaded. DESCRIPTION: Due to the way Asynchronous Monitoring Framework (AMF) interacts with VxFS, AMF has access into VXFS driver even if no file system is mounted without actually holding a module reference on it. Therefore, VxFS can get unloaded despite AMF having access into it. RESOLUTION: The code is modified so as to allow the AMF driver to access the VxFS driver only if at least one file system is mounted. * INCIDENT NO:3145616 TRACKING ID:3140967 SYMPTOM: Veritas File System (VxFS) fails to unload. DESCRIPTION: Asynchronous Monitoring Framework (AMF) may fail to release VxFS module, which makes VxFS unable to unload. RESOLUTION: The code has been modified to fix the unload issue * INCIDENT NO:3178002 TRACKING ID:3177476 SYMPTOM: The Asynchronous Monitoring Framework (AMF) kernel driver causes the system to panic when an event is unregistered. DESCRIPTION: Sometimes due to a race pertinent to the unregistration and notification context, the AMF kernel driver reports an error which leads the system to panic. RESOLUTION: The code is modified to fix the AMF driver issue. * INCIDENT NO:3342983 TRACKING ID:3341320 SYMPTOM: The "Cannot delete event (rid %d) in reaper" error message is repeatedly logged in the Syslog file. DESCRIPTION: This message is logged redundantly into Syslog when the agent calls unregister request to Asynchronous Monitoring Framework (AMF) for an event whose state has already changed. RESOLUTION: The AMF code is modified so that the error message does not appear in the Syslog. * INCIDENT NO:3343013 TRACKING ID:3090229 SYMPTOM: The AMF driver panics the node when the vxconfigd daemon is unresponsive. DESCRIPTION: When the vxconfigd daemon is unresponsive, the libusnp_vxnotify.so library used for disk group notifications goes into an infinite loop. The loop causes AMF to enter an inconsistent state resulting the AMF driver to panic the node. RESOLUTION: The code of AMF driver and libusnp_vxnotify.so library is modified to address infinite loop issue. * INCIDENT NO:3343015 TRACKING ID:3097342 SYMPTOM: The Asynchronous Monitoring Framework (AMF) driver causes a panic in the node when AMF is being stopped. DESCRIPTION: When AMF driver is being stopped, it stops the IMFD daemon. The code to handle this sleeps while holding a lock. This causes AMF driver to panic the node. RESOLUTION: The code is modified for the AMF driver to fix this issue. * INCIDENT NO:3343018 TRACKING ID:3259682 SYMPTOM: Intelligent Monitoring Framework (IMF) registrations for disk group resources fail. DESCRIPTION: If the vxconfigd daemon is unresponsive, then IMFD daemon becomes unresponsive and the IMF registrations fail for the disk group resources. Subsequent attempts to un-configure AMF also fail. RESOLUTION: The IMFD code is modified to fix this problem. PATCH ID:6.0.400.000 * INCIDENT NO:3211055 TRACKING ID:3211054 SYMPTOM: Veritas Cluster Server (VCS) does not support Oracle Linux Unbreakable Enterprise Kernel Release 2 (UEK2) DESCRIPTION: VCS supported Oracle Linux RHEL compatible kernel only and did not support Oracle Linux Unbreakable Enterprise Kernel Release 2. RESOLUTION: Symantec now supports Oracle Linux Unbreakable Enterprise Kernel Release 2 with VCS in VMware environment. VCS supports Oracle Linux 6.4 (UEK2 version should be 2.6.39-400.17.1.el6uek). VCS does not support UEK2 with Oracle Linux 5. * INCIDENT NO:3254691 TRACKING ID:3090229 SYMPTOM: The AMF driver panics the node when the vxconfigd daemon is unresponsive. DESCRIPTION: When the vxconfigd daemon is unresponsive, the libusnp_vxnotify.so library used for disk group notifications goes into an infinite loop. The loop causes AMF to enter an inconsistent state resulting the AMF driver to panic the node. RESOLUTION: The code of AMF driver and libusnp_vxnotify.so library is modified to address infinite loop issue. * INCIDENT NO:3254694 TRACKING ID:3097342 SYMPTOM: The Asynchronous Monitoring Framework (AMF) driver causes a panic in the node when AMF is being stopped. DESCRIPTION: When AMF driver is being stopped, it stops the IMFD daemon. The code to handle this sleeps while holding a lock. This causes AMF driver to panic the node. RESOLUTION: The code is modified for the AMF driver to fix this issue. * INCIDENT NO:3267240 TRACKING ID:3259682 SYMPTOM: Intelligent Monitoring Framework (IMF) registrations for disk group resources fail. DESCRIPTION: If the vxconfigd daemon is unresponsive, then IMFD daemon becomes unresponsive and the IMF registrations fail for the disk group resources. Subsequent attempts to un-configure AMF also fail. RESOLUTION: The IMFD code is modified to fix this problem. INCIDENTS FROM OLD PATCHES: --------------------------- NONE
