There is a limit of 255 characters in the option value and you won't have to maintain a file which some people prefer. Personally, I prefer the file.</P><P></P><P>-- Adam Fox</P></BODY></HTML> Sun, 21 Mar 2010 22:00:38 GMT https://community.netapp.com/t5/ONTAP-Discussions/snapmirror-allow-or-options-snapmirror/m-p/15494#M3486 adamfox 2010-03-21T22:00:38Z Re: snapmirror.allow or options snapmirror https://community.netapp.com/t5/ONTAP-Discussions/snapmirror-allow-or-options-snapmirror/m-p/15502#M3489 <HTML><HEAD></HEAD><BODY><P>By default the options takes preference. I also noticed that the default setting of snapmirror.access is set to legacy.<BR />Does Legacy basically means use snapmirror.allow?</P><P></P><P>Cheers</P></BODY></HTML> Sun, 21 Mar 2010 22:02:59 GMT https://community.netapp.com/t5/ONTAP-Discussions/snapmirror-allow-or-options-snapmirror/m-p/15502#M3489 allblacknz 2010-03-21T22:02:59Z Re: snapmirror.allow or options snapmirror https://community.netapp.com/t5/ONTAP-Discussions/snapmirror-allow-or-options-snapmirror/m-p/15507#M3491 <HTML><HEAD></HEAD><BODY><P>Yes.
