Hi,

we have a two node cluster configured with I/O Fencing...

the hosts are connected to Hitachi Storage...

we are trying to deallocate some LUNS and our storage team is getting this error "processing is disabled because the host is mounted or the device is reserved"

the data disks still have the reservations...and does not want to release them even after deporting the disks...

any insight in this regard is highly appreciated...

If you deported the disks manually they will still have SCSI reservations. You need to clear them using the vxfenadm -p or -x
