In article EADR with Windows 2008 R2<\/a> I described how to use Data Protector EADR for a Windows 2008 R2 server. I also described in former articles that you should be prepared when your Cell Server crashs. To be able to do EADR for your Cell Server I wrote a small script, which allows you to create the needed ISO file, which can be used to recover your Cell Server to the latest state. The Batch file can be downloaded below. The script will be implemented as Post-exec script in the backup of the IDB (for settings see below), in the configured path the ISO will be generated, including the information for the used media during the backup. All stuff within this article is valid for a Cell Manager on Windows 2008 R2.<\/p>\n

\nIt is recommended to test that solution at least once. You may use a imaging tool to create a image from your server.<\/p>\n

\nThe main components of the batch are described below.<\/p>\n

Variables – all values must be provided:<\/strong>
\nSET OMNIHOME=D:\\Program Files\\Omniback<\/code> – Data Protector home folder
\nSET WAIKPATH=C:\\Program Files\\Windows AIK<\/code> – path to WAIK
\nSET CELLSERVER=nbdb0001<\/code> – name of the Cell Server (use output from omnidbutil -show_cell_name)
\nSET ISOPATH=%OMNIHOME%\\tmp\\<\/code> – the folder for the ISO to be created
\nSET SRDFILE=%OMNIHOME%\\Config\\Server\\dr\\srd\\%CELLSERVER%<\/code> – SRDFile – fix values
\nSET P1SFILE=%OMNIHOME%\\Config\\Server\\dr\\p1s\\%CELLSERVER%<\/code> – P1SFile – fix values
\nSET P1SIMAGE=%OMNIHOME%\\Config\\Server\\dr\\p1s\\%CELLSERVER%.img<\/code> – P1SImage – fix values
\nSET NETWORKSHARE=\\\\servername\\share<\/code> – a network share to copy the ISO off the server
\n
\nThe used exit codes (you can also use other exit codes) will mark the session as “failed” in case of errors.<\/p>\n

Do some check before the ISO is created:<\/strong>
\nif not exist “%ISOPATH%” (
\n  mkdir “%ISOPATH%”
\n  if not exist “%ISOPATH%” (
\n    echo Unable to create the ISOPATH – “%ISOPATH%”. Aborting …
\n    exit 500
\n  )
\n)<\/p>\n

if not exist “%WAIKPATH%” (
\n  echo WAIK not found in “%WAIKPATH%”. Aborting …
\n  exit 500
\n)<\/p>\n

The creation of the ISO file:<\/strong>
\n\"%OMNIHOME%\\bin\\omniiso.exe\" -session \"%SESSIONID%\" -cd -iso \"%ISOPATH%%CELLSERVER%.iso\" -srd \"%SRDFILE%\" -rset \"%P1SFILE%\" \"%P1SIMAGE%\" -autoinject -waik \"%WAIKPATH%\"<\/code> – creates the ISO using the given variables
\n\"%OMNIHOME%\\bin\\omnidb.exe\" -session \"%SESSIONID%\" -media > \"%ISOPATH%usedmedia.txt\"<\/code> – writes the used media to a text file
\n\"%OMNIHOME%\\bin\\omnidb.exe\" -session \"%SESSIONID%\" -media -detail >> \"%ISOPATH%usedmedia.txt\"<\/code> – adds some more details for the used media<\/p>\n

\nAt the end the files are copied to the specified share:<\/strong>
\ncopy \"%ISOPATH%%CELLSERVER%.iso\" \"%NETWORKSHARE%\" \/Y<\/code>
\ncopy \"%ISOPATH%usedmedia.txt\" \"%NETWORKSHARE%\" \/Y<\/code><\/p>\n

General information: <\/strong>If you now need EADR for your Cell Server, burn the created ISO image to CDROM or in case you have a HP Server, mount the ISO as virtual media within ILO. The EADR process is very similiar to the already described Windows 2008 R2 EADR process. You have to keep in mind that the drive must be maped directly to the server and the media for the restore must be already mounted, as during the DR process the robotic is not used. In the DRMSHELL you will be prompted to select a drive for the offline restore. Please keep also in mind that you used a media with 64k block size for the backup. It is common to create a separate drive with 64k block size and to use a dedicated pool with dedicated media for the backup of the IDB. Other backup jobs might use other drives with higher block size, if available. <\/p>\n

Requirements:<\/strong> The article was created with Data Protector patches installed in January 2011 and valid for the mentioned products and versions only (patches from December and additional SSP applied). For further requirements, please refer to the article mentioned above.<\/p>\n

Settings for the IDB backup:<\/strong><\/p>\n
