Hi,  The Protect_data option is only used for Striped Metas. For concat theer is no option to protect the data while you are expanding or converting meta..  Thanks Amita
Hi All,  I am trying to do this only for a study purpose.I am trying to convert a triped meta to concatenated.  Fist I used this file to preview  Convert Meta 2C9 config=concatenated;    This preview completd successfully    Execute a symconfigure operation for symmetrix '00019010xxxx' (y/ ) ? y   A Configuration Change operation is in progress. Please wait...      Establishing a configuration change session...............Established.     Processing symmetrix 000190xxxx     {        convert meta 02C9, config=Concatenated, protect_data=FALSE;     }      Performing Access checks..................................Allowed.     Checking Device Reservations..............................Allowed.     Submitting configuration changes..........................Submitted     Locking devices...........................................Locked.     Validating configuration changes..........................Validated.     Closing configuration change request......................Closed.     Terminating the configuration change session..............Done.  The configuration change session has completed successfully.  But I found by default it taking protect_data=FALSE;  Then I changed the command file like this  Convert Meta 2C9 config=concatenated,protect_data=True;    Now preview failing with error  C:\Documents and Settings\aratnan001>symconfigure -sid xxx preview -f 1.txt -v  Execute a symconfigure operation for symmetrix '000190xxxx' (y/ ) ? y   A Configuration Change operation is in progress. Please wait...      Establishing a configuration change session...............Established.      Error occurred while Defining change number 1:     Meta protection is only available for expanding striped metadevices or chang ing stripe size     Terminating the configuration change session..............Done.  The configuration change session has failed.   So I just want to understand this situation.Is this means that  1.striped meta can not be convert to concatenated with preserving data on existing meta? 2. by default changing from striped to concatenated will  protect the data ?
converting striped meta to concatenated meta
