IOM (ESM) removed
An IOM has either been removed from the drive shelf or is present but is being reported as removed because it is not seated correctly.
Although the drive shelf is still operational, you should correct this failure as soon as possible. If the other IOM or its communication path fails, all I/O to that drive shelf will fail.
Both IOMs in the same drive shelf must have the same firmware version and be of the same hardware type.
Make sure you correctly identify the affected IOM. Removing the remaining optimal IOM or disconnecting drive shelf cables to it while I/O is in progress can cause data loss.
Before proceeding, ensure that the OK to remove
field in the Details area indicates Yes. If No is displayed, it indicates that there is another component that must be serviced first. Always select Recheck
prior to and after servicing a component to ensure that there aren't any new problems that may affect the component you plan to service.
Always use proper anti-static protection when handling components. Touching components without using a grounding wrist strap may damage equipment.
Recovery Steps
Is the affected IOM shown in the Location field in the Details area still in the drive shelf or has it been removed?
If the IOM is still in the drive shelf, go to step 2.
If the IOM has been removed, go to step 5.
Without removing the cables, remove the IOM.
Check the connectors on both the IOM and inside the shelf that housed the IOM for any problems such as bent or dirty pins and fix if necessary.
Reinsert the IOM, and then go to step 6.
Reinsert the IOM or, if necessary, replace it with a new one.
Wait 40 seconds, then select Recheck to ensure the problem has been resolved.
