In the post Create
SecureString File we wrote a tool to create a secure string file. Now we put
that SecureString file to use, develop the standard code for "ONTAP-Buttons", and illustrate this with an example to Get Node Information for
all nodes in a Clustered Data ONTAP cluster.
Batch File In
...\ONTAP-Buttons
The file GetNodeInfo.BAT has this content:
PowerShell.EXE
.\PS\GetNodeInfo.PS1 -User admin -Cluster 192.168.168.200 -GetCredential
PowerShell
Script in ...\ONTAP-Buttons\PS
The file GetNodeInfo.PS1 has the following content - any
line that starts with <#S#> is standard content:
<#S#>
Param(
<#S#> [String]$Title = "Get Node Info",
## TITLE
<#S#> [String]$User,

GetNodeInfo in
Action
Double-click GetNodeInfo.BAT which has already been
specified with Cluster User, Cluster Management IP Address, and we have already
generated the credential file -

GetNodeInfo.BAT
- and, bam, node info is displayed!
