PROBLEM DESCRIPTION:
The review and improvement of Solaris diagnostic messages have uncovered
a hole in message retention for the E10000 platform. After a panic
reboot, hpost performs a destructive scrub of memory effectively
destroying the message buffer and any information it may have contained
for problem diagnosis. Since we cannot change the destructive nature
of hpost, the only reliable solution is to capture what is output on
the console.
All E10000 servers using SSP release 3.1.1 and higher have the ability
to log console output via the netcon logging feature. This is handled
by the syslog local1 facility and is disabled by default. Beginning
with release 3.4, this feature will be enabled by default but prior
releases will need to be changed manually.
Enabling the feature has negligible effects on performance but disk
space may be of concern depending on current disk and console usage.
Although we don't anticipate anyone having issues with disk space, disk
cleanup may be necessary to avoid full filesystem scenarios.
Currently, nine netcon logs are retained per configured domain and
expire once a week. File sizes can vary greatly depending on console
usage so tuning may be required to reduce the amount of disk space
needed to accommodate these new logs.
IMPLEMENTATION:
---
| | MANDATORY (Fully Pro-Active)
---
---
| X | CONTROLLED PRO-ACTIVE (per Sun Geo Plan)
---
---
| | REACTIVE (As Required)

CORRECTIVE ACTION:
Enterprise Customers and authorized Field Service Representatives may
avoid the above mentioned problem by following the recommendations
as shown below:
To enable netcon logging for SSP release 3.1.1, 3.2 and 3.3:
1. Login as root.
2. Uncomment local1.debug in /etc/syslog.conf.
3. Restart syslogd.
# /etc/init.d/syslog stop
# /etc/init.d/syslog start
To enable netcon logging for SSP releases prior to 3.1.1, see Infodoc
#15786.
To reduce the number of aged log files to retain:
1. Login as root.
2. Edit /opt/SUNWssp/bin/newssplog.
3. Change variable MAX=8 to MAX=3.
- This will reduce the number of aged files from 9 weeks to 4
weeks.
COMMENTS:
--------------------------------------------------------------------------
Implementation Footnote:
i) In case of MANDATORY FINs, Enterprise Services will attempt to
contact all affected customers to recommend implementation of
the FIN.
ii) For CONTROLLED PROACTIVE FINs, Enterprise Services mission critical
support teams will recommend implementation of the FIN (to their
respective accounts), at the convenience of the customer.
iii) For REACTIVE FINs, Enterprise Services will implement the FIN as the
need arises.
