Solution Type FAB (standard) Sure Solution 1000668.1 : The thermcal utility should be run if a Centerplane or Centerplane Support Board (CSB) is replaced on the Sun Fire 12K/15K/E20K/E25K.
PreviouslyPublishedAs 200880 Product Sun Fire 12K Server Sun Fire E20K Server Sun Fire 15K Server Sun Fire E25K Server Bug Id <SUNBUG: 4959202> - SMS should improve ASIC temperature calculation precision. <SUNBUG: 4959175> - Thermcal does not indicate SMS needs to be restarted. Part
Impact When a Centerplane or Centerplane Support Board (CSB) is replaced in a Sun Fire 12K/15K/E20K/E25K Server, the thermcal utility must be executed following replacement. Failure to implement this action may lead to over/under temperature conditions being reported by the ESMD daemon for the ASICS on the logical half of the Centerplane. An additional impact is that the the logical half of the Centerplane (CP) needs to remain powered off for a 30 minute period. As this is part of the process to replace a CSB unit, the logical CP will have to be powered off anyway. In the case of Centerplane replacement, thermcal must be run on both logical halfs. After the thermcal operation is complete, SMS on the Main SC will have to be stopped and restarted. Any situation where a new combination of CSB and logical CP half are combined may cause this issue. In this case, thermcal will have to be executed. Below is a sample of ASIC temperatures recorded before and after a specific CSB replacement. Note the differences for the same ASIC locations. Before replacing CS1: sms-svc> showenvironment -p temps | grep CP SCPER at SCPER1 max1617a AMB 0 Temp 24.00 C 13.0 sec OK sms-svc> showenvironment -p temps | grep CP Symptoms Resolution Run the "thermcal" utility following any Centerplane or CSB replacement on a Sun Fire 12K/15K/E20K/E25K Server. Special instructions will be issued when an authorization code is requested for a Centerplane or CSB replacement. As of SMS 1.5, thermcal and the accompanying man page thermcal (1m) are bundled. The executable is /opt/SUNWSMS/bin/thermcal. For previous versions of SMS, a thermcal binary and instructions on its usage are available at the URL below: http://pts-platform/twiki/bin/view/Products/SCthermcal Modification History Date: 15-NOV-2005
