STM Release Notes for HP-UX 11i v3 September 2012 release

Workaround: You can safely ignore the Error Recovery Info information.
• Symptom: OnlineDiag does not work properly when the length of the system name exceeds
8 characters.
Problem: When the length of the hostname for a system name exceeds 8 characters,
OnlineDiag cannot retrieve the hostname. So, OnlineDiag cannot function as expected.
Workaround: Change the default values of the expanded_node_host_names and
uname_eoverflow kernel parameters by completing the following steps:
1. kctune expanded_node_host_names=1
2. kctune uname_eoverflow=0
3. /sbin/init.d/diagnostic stop
4. /sbin/init.d/diagnostic start
• Symptom: System port scan software can cause the diagmond process to exit.
Problem: The system port which the diagmond process uses should be explicitly used for
diagmond. If other applications try to access this port, the diagmond process exits.
Workaround:
The Diagnostic running on the system can be configured to allow only local connections. After
this, an attempt to send an IPC message to a non-local port will be rejected.
To enable this functionality (allow only local connections), follow the steps below:
1. Shutdown both STM and the EMS HW Monitors.
2. Create /var/stm/config/sys/local_only file.
3. Restart STM and the EMS HW Monitors in that order.
When enabled, the STM will no longer accept connections from remote systems.
To disable this functionality, follow the steps below:
1. Shutdown both STM and the EMS HW Monitors
2. Remove /var/stm/config/sys/local_only file.
3. Restart STM and the EMS HW Monitors in that order.
When both STM and the EMS HW Monitors are not shutdown, and the local_only file is
created, IPC messages timeout and fail. This will result in the following problems:
1. Tools will not start from the UI
2. Monitors will not be able to send events to PSM, so the state of the devices will not be
updated and set_fixed will not be able to display or update the state of devices.
• Symptom: The disk_em monitors reports incorrect events for errors of ESCSI_LOG_ERR type.
Problem: The disk_em is not designed to decode ESCSI_LOG_ERR, as ESCSI_LOG_ERR
related to Asterope events for LUN path H/W path. The disk_em monitors are at the
hardware level and not path level. Therefore, the OnlineDiag does not support these events.
Workaround: The OnlineDiag provides a separate decoder which decodes the
ESCSI_LOG_ERR events and display in the logtool.
Obsolescence
NOTE: Starting with HP-UX 11i v3 March 2009 release, OnlineDiag (including STM) will be in
support mode. Moving forward, no new enhancements will be made to OnlineDiag (including
STM). Only Critical / Serious defects will be analyzed. For the most current information about
OnlineDiag obsolescence, see the following document at http://www.hp.com/go/
