When running cfgmgr to enable missing paths to disks we are getting the following error for every missing path:

Method error (/usr/lib/methods/cfgefscsi -l fscsi3 ):
0514-061 Cannot find a child device.

Any advice?

ML3! First steip is update your code, ML3 is out of support by years.

What storage is it?
Was it working?
What did you change?

DS4300 through SVC. It was working before a powerdown! Just noticed, however, on one of the switches a port is offline, could this be affecting it? If so is there a quick way to online it and re-run cfgmgr? As it is MPIO we are still running on 6 paths to the hdisk.

Cheers

The error means that the fiber adapter detects an open loop which is in correlation with the offline port in the switch. Enable the port from the switch side and run a cfgmgr - that should fix things, if there are not any hardware errors like broken cable etc

Thanks fellahs.

This can also mean just what it says - "Cannot find a child device". This happens because the cfgmgr doesn't find any LUNs attached to that HBA, the root cause of your missing paths. You might want to re-check your zoning and LUN masking.

Replaced the Gbic and fibre and ran cfgmgr on the lpar which got rid of the missing paths and offline port, but has left a few hdisks in a defined state. cfgmgr also produced another error which points towards drivers I think.
