Mirrorview /A and scripting LUN promotes etc.

Question

Hi all,

First thread, so please do be gentle.

We currently run 2 x CX3-20s with mirrorview A between the 2 array members for certain critical LUNs.

I've been given the task of scripting mirrorview member promotion as part of streamlining our DR processes. I have the Mirrorview CLI reference and things are fairly clear.

However, does anyone else here have any experience in scripting with navicli (for any tasks) or better still for performing these sorts of tasks. Would any of you be willing to share your code to help an updstart like myself?

Failing that, any tips on possible gotchas etc. would be extremely useful.

Thanks in advance.

What type of system will you be running these jobs from (Windows, Linux, AIX, etc)? I have examples of scripts using vbscript on Windows that might be helpful to get you going.

Well, it could be either Linux or Windows - but if you assume Windows, your VBscript would suit well. Anything you can would be of great help.

Sorry it has taken me so long to get back to you. Here is how I build out the commands using Set objShell = wscript.createObject('wscript.shell') dim naviseccli, navi_temp navi_temp = 'C:\PROGRA~1\EMC\NAVISP~2
aviseccli.exe'naviseccli = path_with_quotes(navi_temp)naviseccli = naviseccli & ' -user USERNAME -password PASSWORD -scope 0' command = naviseccli & ' -h 'command = command & source_ipcommand = command & ' mirror -async -addimage -name 'command = command & mirror_namecommand = command & ' -arrayhost 'command = command & remote_ipcommand = command & ' -lun 'command = command & remote_alucommand = command & ' -recoverypolicy auto -syncrate medium -enddelay 15' objshell.Run '%comspec% /c ' & command,,True The last part, objshell.Run is what issues the command. It opens another command prompt and will continue on with the remaining code when that window closes. The window closes when the command completes which works nicely. You can pass arguements to your vbscirpt as well. So you can do something like lun_promote.vbs TARGET_ARRAY MIRRORSESSION . Then within the script you can grab those variables and use them to build out a command like I did above: Set args = WScript.Arguments Dim remote_ipDim mirror_sess If WScript.Arguments.Count < 2 then Wscript.QuitElse remote_ip = args.Item(0)mirror_sess = args.Item(1)End if

remember to use the naviSECcli commands only - navicli will be going away in the future. Also, you will need to setup a security file to hold your username/password stuff to automate the commands.

Glen I've noticed that only my user account can authenticate against the array. Is there a way to have the system account for a server to use that security file as well.

As of now I'm forced to hard code the username and password into the script.

kelleg · Answer

Do you have a copy of the Navisphere CLI document? There is a very good explanation of the security setting for naviseccli. glen

Thanks Glen. I went through it and finally got the security file working. My problem was I was creating the file with my account on the server and not the system account. Just created a script to create the security file and ran that from cron. Worked great. Thanks again.
