ChangesN/ACauseThe SIM failure is caused by a missed heartbeat signal. The SIM that detects the heartbeat timeouttakes the action of disabling it's peer (assuming that it is hung or otherwise non-functional). See CR 6803801 for more details. Sun engineering has very strong evidence to suggest that upgrading the SIM firmware to 3R24 resolves this issue. See also FAB 1021661.1 (J4400 SIM cards randomly failing due to heartbeat timeout) SolutionSteps to follow:1. Physically re-seat the SIM module. This item is hot-pluggable, and as far as the Appliance is concerned, it is not present, so it is safe to re-seat. 2. Upgrade system software to 2010.Q1 or later. For installing Sun Storage 7000 Software Update 2010.Q1.1.0 or later, the Release Notes can be found here: http://wikis.sun.com/display/FishWorks/ak-2010.02.09.1.0+Release+Notes and the release itself is linked from the Software Updates page: http://wikis.sun.com/display/FishWorks/Software+Updates 3. Wait for the SIM firmware update to complete. If there's no progress monitor available, allow 15 minutes per JBOD. 4. Navigate in the BUI to Maintenance->Problems. Select any path faults, if present. Click the 'Mark Repaired' button. It is possible to lose access to your storage pool for the duration of the SIM failure, which in turn could cause a reboot and/or failure. This would generally only happen if incorrectly cabled (i.e. no alternate path available), or in the case of multiple SIM failures. NOTE: Under no circumstances should you attempt to update the SIM firmware or anything on the appliance other than the system software without the direct involvement of Technical Support.
