That's a zoning problem or the host isn't in any storage group on the CX yet. :)

Probably you have disconnected some cables after your last reboot. Even though there is no more connectiopn available, the driver name server cache still has the entries in it. You may remove this with 'rad' command.

Hello Ivan,

The reason ct_query failed you are getting because you don't have any devices connected to the fibre card at present.

Normally you will see these messages, if you run ioscan, and you don't have any devices connected to that card.

Check any devices connected to that card or not.

Thanks

this happens because the fc cable was disconnected after system came up. And FC drives still has this information in cache.

Check what has happened in your case.
