The trespass events are seen with the error code "606" these are something which is caused by the host and the possible reasons are as follows:
The primary reason for the trespasses is that the host is periodically aborting commands. A host will do this when it thinks a command is taking too long. That happens when the array is overloaded and/or the host timeout is not long enough.
This also occurs when the host senses a path failure or if a LUN is trespassed by another host if in a cluster.
This also occurs when the host senses a path failure or if a LUN is trespassed by another host if in a cluster.
Resolution
- The events of 606 unitshutdown are received due to the lower redirector of VNX Storage Array. When a pool private LUN is trespassing very few times per week, this is by no means excessive nor would it cause any performance problems.
- These alerts are received by the user because he is not using default template of EMC.
- With reference to Call_Home_Template_7.33.0.11, these events are not checked. Since there is no impact on the performance by these events, all that is necessary is to un-check the event code from the template or use latest default call_home template.
