First off, I wanted to my apologizes for falling so behind on my blogging. I could make a list of reasons, both personal and work related , but I’ll not, and instead say sorry.
I plan on making some headway on the blog front, both here and at vbrainstorm.com Expect to see some new changes at vbrainstorm.com soon.
Now, on to the blog post!
I recently attended a EMC training class, titled VNX Unified Storage Performance Workshop, and we worked a lot of .nar files. As soon as I got back in the office, I found I wanted to combine .nar files to get a larger date range when looking at them.
I did a little Googleing and found this post.
Merge Multiple EMC NAR files with PowerShell
by David Muegge
I spend some time working with what code he had and came up with this.
$userinput = Read-Host “Enter case # or description:”
$Date = (Get-Date -format “MM-dd-yyyy”)
$TempFile = “E:emcnar_outTemp.nar”
New-Item E:emcnar_out$Date -type directory -Force
$OutputFile = “E:emcnar_out$Date” + “Merge – $userinput” + ” – $Date” + “.nar”
$NarFiles = Get-Childitem “E:emcnar_input”$filecount = 0
foreach($NFile in $NarFiles){if($filecount -eq 0){Copy-Item $NFile.FullName $OutputFile}Else{
Copy-Item $OutputFile $TempFile
Remove-Item $OutputFile
./NaviSECCli.exe analyzer -archivemerge -data $TempFile $NFile.FullName -out $OutputFile}
$filecount ++
}
It prompts you for the case# or a description of your choice. It will append this into the file name.
This outputs the files to E:emcnar_out with a sub-folder for the date. with a temp location of E:emcnar_outTemp.nar. The output file name come out like Merge – input – date .nar
Credit goes to David for the original script.
I hope someone gets some use from this.
