    yes,you got it right. In addition use the '-e ignore' switch with vxrestore to ignore any extent attribute warning messages. Incase every extent attribute is to be preserved, use the commands interactively per restore, -outside of the script.

    technote say that If I use  file instead of stdin

    then  vxrestore will not  ask interactive question like set mode  ? y/n

    Is my understanding right ?

    only for some restores the user input might be prompted & not for others ..like only for specific FS, vxrestore might want to correct/reset the permissions/mode etc and seek user confirmation

    However if it lookinfor  input like 'y' from user , it should be the case in each volume restore.

    How come it restores few volumes in non-interactive mode and then it fail for one

    Hi Symsonu,

                              You'll need to consider using a temporary dump file to read inputs for vxrestore, rather than using the STDIN -if you must use a non-interactive script.

    In you command you use '-'   (after the -f argument) which implies reading from stdin.

    There are situations where vxrestore expects user input and this method of using stdin might not work everytime inside scripts.  Theres an old technote that has more details on using the workaround but the advised steps are still valid:
