It is possible to lose events with this method if the event comes in between the time the SEL was read and it is cleared. The probability is low, of course, but it is there. I'm not sure how important this is to you.
IPMI does have a mechanism to safely clear the SEL without losing events, but it requires a sort of interlock, and it doesn't appear that ipmitool has this. It would be possible to implement with a "save and clear" operation, or by printing the sequence number as part of the list and then giving the sequence number as part of the clear (and the clear will fail if the sequence number has changed). -corey > > > Andy > > > > *From:* Gnanasekar Loganathan [mailto:l.gnanase...@gmail.com] > *Sent:* Monday, March 01, 2010 11:49 PM > *To:* Andy Cress > *Cc:* Ipmitool-devel@lists.sourceforge.net > *Subject:* Re: [Ipmitool-devel] "ipmitool sel delete 0x40" Unable to > delete entry64: Invalid command > > > > Hi Andy, > > Thanks for you info.. > May i know how the the SEL records are recorded in the memory... > > Please look the below logs.... > > *# ipmitool sel info* > SEL Information > Version : 1.5 (v1.5, v2 compliant) > Entries : 3008 > Free Space : 0 bytes > Percent Used : 100% > *Last Add Time : 05/15/2009 02:06:03 > Last Del Time : 06/23/2009 03:34:08 > *Overflow : true > Supported Cmds : 'Reserve' > > * # ipmitool sel list first 10* > 1 | 06/23/2009 | 03:34:11 | Processor #0x69 | Limit Exceeded > 2 | 06/23/2009 | 03:34:11 | Processor #0x69 | Limit Not Exceeded > 3 | 06/23/2009 | 03:35:11 | Processor #0x69 | Limit Not Exceeded > 4 | 06/23/2009 | 03:35:11 | Processor #0x69 | Limit Exceeded > 5 | 06/23/2009 | 03:35:27 | Processor #0x69 | Limit Exceeded > 6 | 06/23/2009 | 03:35:27 | Processor #0x69 | Limit Not Exceeded > 7 | 06/23/2009 | 03:35:29 | Processor #0x69 | Limit Not Exceeded > 8 | 06/23/2009 | 03:35:29 | Processor #0x69 | Limit Exceeded > 9 | 06/23/2009 | 03:35:32 | Processor #0x69 | Limit Exceeded > a | 06/23/2009 | 03:35:32 | Processor #0x69 | Limit Not Exceeded > > *# ipmitool sel list last 10* > bb7 | 05/15/2009 | 02:05:58 | Processor #0x69 | Limit Not Exceeded > bb8 | 05/15/2009 | 02:05:59 | Processor #0x69 | Limit Not Exceeded > bb9 | 05/15/2009 | 02:05:59 | Processor #0x69 | Limit Exceeded > bba | 05/15/2009 | 02:06:00 | Processor #0x69 | Limit Exceeded > bbb | 05/15/2009 | 02:06:00 | Processor #0x69 | Limit Not Exceeded > bbc | 05/15/2009 | 02:06:02 | Processor #0x69 | Limit Not Exceeded > bbd | 05/15/2009 | 02:06:02 | Processor #0x69 | Limit Exceeded > bbe | 05/15/2009 | 02:06:02 | Processor #0x69 | Limit Exceeded > bbf | 05/15/2009 | 02:06:02 | Processor #0x69 | Limit Not Exceeded > bc0 | 05/15/2009 | 02:06:03 | Processor #0x69 | Limit Not Exceeded > > *Last Add Time : 05/15/2009 02:06:03 --> Here the Last add date is > lesser than the delete date > Last Del Time : 06/23/2009 03:34:08 > * > But the sel entries in "ipmitool sel list first 10" shows greater > than last Add/Del time.... > > How the SEL records are stored? > Is it record like circular ? > > > Thanks, > Gnana > > On Fri, Feb 26, 2010 at 7:56 PM, Andy Cress <andy.cr...@us.kontron.com > <mailto:andy.cr...@us.kontron.com>> wrote: > > It is very poor policy to only delete some of the SEL records.
