Serviceguard Version A.11.16 Release Notes, Second Edition Patches and Fixes in this Version • What was the resolution?

Serviceguard Version A.11.16 Release Notes, Second Edition Patches and Fixes in this Version From: Disks which do not have IDs cannot be included in the topology description. Use pvcreate(1M) to initialize a disk for LVM or, use vxdiskadm(1M) to initialize a disk for VxVM. To: Disks were discovered which are not in use by either LVM or VxVM. Use pvcreate(1M) to initialize a disk for LVM or, use vxdiskadm(1M) to initialize a disk for VxVM.

Serviceguard Version A.11.16 Release Notes, Second Edition Patches and Fixes in this Version JAGae60038: cmapplyconf prints bogus message when cl_disk_init fails • What is the problem?

Serviceguard Version A.11.16 Release Notes, Second Edition Known Problems and Workarounds Known Problems and Workarounds JAGaf36760: Uncorrectable write errors on vxvm volumes. • What is the problem? Configurations using greater than 256 LUNs with VxVM on 11i v2 September 2004 update experience uncorrectable write errors. • What is the workaround? Restrict configurations to a maximum of 256 LUNs. Please continue to check the status of this problem at http://www2.itrc.hp.com for updated information.

Serviceguard Version A.11.16 Release Notes, Second Edition Known Problems and Workarounds JAGaf24444: Unable to receive device query message • What is the problem? Serviceguard configuration commands (cmquerycl, etc) may fail if you have no LVM volume groups configured on one or more of your systems. • What is the workaround? The work around is to create a volume group and import it on all nodes that have no LVM volume groups. There is a patch for Serviceguard A.11.14: PHSS_31015. Patch numbers for A.
Serviceguard Version A.11.16 Release Notes, Second Edition Known Problems and Workarounds 3. Now, when you are able to take the entire cluster down, run cmhaltcl -f on one of the nodes that is still running in the Serviceguard cluster. 4. After the cluster has successfully halted, start the Serviceguard cluster on the nodes that were upgraded to CVM 3.5. To do this, you must not run the normal cmruncl command to start up the Serviceguard cluster, since that will attempt to start all cluster nodes.
Serviceguard Version A.11.16 Release Notes, Second Edition Known Problems and Workarounds JAGaf08686: It is not possible to configure some combinations of roles • What was the problem? Duplicate roles and conflicting roles are not allowed in Access Control Policies. This is especially problematic when wild cards are used. For example, if ANY_USER from ANY_SERVICEGUARD_NODE has a role, no other Access Control Policy can be created that would not conflict or be redundant.
Serviceguard Version A.11.16 Release Notes, Second Edition Known Problems and Workarounds JAGae87101: LOG_PERIODIC messages should not be logged at log level 1 • What is the problem? Because periodic messages show up very often, enabling this sort of debug logging will fill up syslog.log very quickly. • What is the workaround? There is no workaround. JAGae62205: Serviceguard package cannot be restarted after hardware monitoring is re-enabled.
Serviceguard Version A.11.16 Release Notes, Second Edition Known Problems and Workarounds — Halt Serviceguard on the node, then restart it. This will create the monitor request. Then start the package. JAGad39695 User error can result in "ghost" services: • What is the problem? When the package was shutdown, references for this service had already been removed, and the service failed while the package was halting. Since the service no longer exists, it cannot be halted manually.
Serviceguard Version A.11.16 Release Notes, Second Edition Known Problems and Workarounds — Another solution is to add a new package with a service name matching that originally deleted and then halt the service with cmhaltserv. This would allow the problem to be resolved without halting either the package, node or cluster. — Alternatively, if the cluster/node were halted and re-started the problem would go away.
