Hello

I have configure my box RedHat 6.2 with DM mapping and CX4-120 and I have configure
zonning.

So all thinks go good but I have removed the LUN from storage group (not safety method).

After that the mapping device still present for this I reboot the server.
And I have removed the device with the command line "echo 1 > /sys/block/sd{e,d,c,h}/device/delete "
although when I reset host adaptator " echo "- - -" > /sys/class/scsi_host/host2/scan" the device will be appear and when I lanuch lssci command I can view the device disk.

Please have you an explication for this phenomenon.

please post the output of this
6.2 is 5 versions out of date

also please post the error you get from this ( if you get one - i am betting you do get an error)
