Re: Can't Remove No H/W Device

It's on a SAN, so possibly the FC/SCSI bridge the L20 is behind is still advertising itself but some kind of security is blocking it?

I find it odd -fnCtape reported an autoch class device.

So is the L20 still on the SAN? Maybe it's just zoned so it can't be seen, but the name server in the switch is still telling about it?

Since you rebooted, I would think any cache of the device in the iotree would be wiped clean, so the server must be relearning of the device from the SAN.
