Enabling Enhanced Redundant Power Scrub
For T0682 H02 ABE and later, an enhanced version of the Redundant Power Scrub test is available
for legacy S-series enclosures. It provides independent battery testing and an extended load test
for the bulk power supplies.
NOTE: With this new version of Redundant Power Scrub, the action can take up to 25 minutes
to complete. The new battery scrub is significantly enhanced in its ability to detect weak or failed
batteries. For systems with many old batteries (over 5 years old), the battery scrub might call out
multiple batteries for replacement
This enhanced version of the Redundant Power Scrub must be enabled in your OSMCONF file,
but not until these prerequisites are met:
• All enclosures must be updated with a new PIB-to-PIB crossover cable (see FCO 44440 for
details).
• OSM T0682 H02 ABE or later is installed.
Once the prerequisites are met, add this entry into your OSMCONF file:
PowerScrubVersion = 3
The default test interval for this new version is 7 days instead of every 24 hours ( as was the default
for the older version). HP recommends leaving the default as 7 days unless an event requires a
reduced time between scrubs.
To change the test interval for the enhanced Redundant Power Scrub test, add this entry into your
OSMCONF file:
DailyScrubTestingInterval = n
To make changes to your OSMCONF file take effect, see “Creating and Using an OSMCONF
File” (page 15).
Disabling Creation of System Inventory Files
For T0682H02 AAM and later, OSM has automatic system inventory file creation enabled by
default. With this feature enabled, system inventory files are created whenever Periodic Incident
Reports (IRs) are created, and attached to these IRs if the “Suppress Attachment files on Periodic
IRs” option is deselected in the OSM Notification Director Preferences dialog box.
NOTE: A system inventory file will not be created if a Periodic IR is generated before OSM
completes system discovery.
To disable automatic creation of system inventory files, you must set the following OSMCONF
parameter to “OFF:”
INVENTORY_STATE = ON
The ”ENABLE_INVENTORY = ON” parameter used to configure system inventory files in earlier
OSM releases no longer has any effect and should be removed from your OSMCONF file. The
current ”INVENTORY_STATE = ON” parameter can be copied to an existing OSMCONF from
the OSMINI template provided with T0682 AAM or later.
To create an OSMCONF file from the OSMINI, or to put OSM configuration file changes into
effect when OSM processes are already running, see “Creating and Using an OSMCONF File”.
For information on initiating Periodic incident reports and viewing attachment files, see the OSM
Notification Director online help.
This automatic system inventory feature should not be confused with the standalone OSM System
Inventory Tool, which can be used to create inventory files from multiple NonStop systems (see
“OSM System Inventory Tool” (page 69).
