Do you have establish the HDR setup as describes in the manual ? A server that has been setuped as a standalone server can't be promoted to secondary server. The initial promotion to secondary is done while the server is in recovering mode 1. make a backup of the primary "onbar -b -L0" or "ontape -s -L0" 2. set the primary up : onmode -d primary server1 2. rcopies the oncfg_server1.servernum and the ixbar.servernum files 3. do a physical restore on the secondary "onbar -r -p" or "ontape -p" 4. set the secondary up : onmode -d secondary server2 5. the synchronising starts with the restore of the last logged activities since the full backup look in the log file , if you see : DR: Start failure recovery from tape ... then type "onbar -r -l" or "ontape -l" else you see DR: Start failure recovery from disk ... and you have nothing to do cause the last logged activities are still on disk and are not overwritten. So HDR will synchronise without restoring logging from tapes. What's the status of HDR of both systemms : onstat -g dri yves (sorry for the html, it's not me, the format in outlook is "text", i can't find) ------_=_NextPart_001_01C347A8.D97FE020 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN"> <HTML> <HEAD> <META HTTP-EQUIV=3D"Content-Type" CONTENT=3D"text/html; = charset=3Diso-8859-1"> <META NAME=3D"Generator" CONTENT=3D"MS Exchange Server version = 5.5.2653.12"> <TITLE>RE: hdr installation [1545] </TITLE> </HEAD> <BODY> Do you have establish the HDR setup as describes in = the manual ?
