Bulk SM relationsship creation with Powershell ?

Hi there!

Has anyone experience with creation of Snapmirror Relationsships in bulk, i talk about more than 50....

I think about to create a txt oder csv file where SourceVOL and DestVOL is entered and the cmdlet reads each row/column and create the relationship beetween the 2 Controllers.

Any ideas or sample script are welcome.

Thx

Hi Taner,

DataOntap Toolkit has a cmdlet called Invoke-NaSnapmirrorInitialize which helps in creation of snapmirror relationship between source controller volume and destination controller volume.

To Get detailed information about the cmdlet you can run

Get-Help Invoke-NaSnapmirrorInitialize -Detailed

In order to scriptize the snapmirror relationship you can try something like below, create a csv file with entries as below specifying the destination/source volume and controller name.

DestinationController	DestinationVolumeName	SourceController	SourceVolumeName
benson	benvol1	dunn	dunvol1
benson	benvol2	dunn	dunvol2
benson	benvol3	dunn	dunvol3
benson	benvol4	dunn	dunvol4
benson	benvol5	dunn	dunvol5
benson	benvol6	dunn	dunvol6
benson	benvol7	dunn	dunvol7
benson	benvol8	dunn	dunvol8
benson	benvol9	dunn	dunvol9
benson	benvol10	dunn	dunvol10
benson	benvol11	dunn	dunvol11
benson	benvol12	dunn	dunvol12
benson	benvol13	dunn	dunvol13

Then through your powershell prompt, import the csv and feed it to Invoke-NaSnapmirrorInitialize to iterate though the csv and create snapmirror relationships for each destination and source volume

PS C:\> $snapinfo = Import-Csv C:\Users\vinith\Desktop\snapinfo.csv
PS C:\> $snapinfo | ForEach-Object {Invoke-NaSnapmirrorInitialize '$_.destinationcontroller:$_.destinationvolumename' '$_.sourcecontroller:$_.sourcevolumename' }

Hi Vinith,

I am very new to Power Shell scripting aand would like to know in your example do the destination volume have to exist for this to work ?

If they do, what would the script look like to create the new destination volumes ?

Richard
