well it works fine, since thin was pretty  new to me. I forgot the binding step and the Unix team complains there are not able to format the disk. my dev was 17GB, he was ableto see the device size as17GB. I  had to  complete the  binding step and the  good part is once the device is bound it  will tell you which pool does it bound to.  thin devs only consumes the block once you have bound and start writing to the new blocks, you can grow up to you device capacity like 17GB. once its full you need to add another tdev.
Hi  Normally Thin devices gets storage from thin pools. If thin devices are unbound then that thin device is not part of any thin pools. But it has capacity value.. Please tell me where this thin devices gets the capacity if it not part of thin pool. Below is the sample unbound thin device where it shows capacity value and Thin pool name shows as N/A.   Device Physical Name     : Not Visible      Device Symmetrix Name    : 1AB6     Device Serial ID         : N/A     Symmetrix ID             : 001234512345      Number of RAID Groups    : 0      Attached BCV Device      : N/A      Attached VDEV TGT Device : N/A      Vendor ID                : EMC     Product ID               : SYMMETRIX           Product Revision         : 5874     Device WWN               : 00000000000000000000000000000000     Device Emulation Type    : FBA                Device Defined Label Type: N/A                Device Defined Label     : N/A                Device Sub System Id     : 0x0015     Cache Partition Name     : DEFAULT_PARTITION     Thin Pool Name           : N/A       Device Block Size        : 512      Device Capacity         {          Cylinders            :      10923         Tracks               :     163845         512-byte Blocks      :   20972160         MegaBytes            :      10240         KiloBytes            :   10486080         }   Please let me know if you need further information. I really appreciate your help    Message was edited by: SymmetrixForumsModerator: I modified the WWN and SN.
