hello,

could you help me on WINDWOS CLI

I want to know how to redirect the result of a CLI command to a file
For exemple:


3par1 cli% showvv
------Rsvd(MB)------- --(MB)--
Id Name Prov Type CopyOf BsId Rd -Detailed_State- Adm Snp Usr VSize
1 .srdata full base --- 1 RW normal 0 0 81920 81920
0 admin full base --- 0 RW normal 0 0 10240 10240

Why not run the commands from Interactive CLI on the SP ?
Use Putty and log output to a text file
(logging -> click printable output - select were to store file & name (tips change extention to .txt)

ready

I do it all the time and from batch files and Powershell so that I can then read in the results and parse it and act on what I find. The trick is run it from a command prompt, the CLI just loads a shell for you, forget that, not needed.

Here is a simple scrip that I run to output volumes that meet a search name. It pumps the data to a file using the CLI

Designed for 2 arrays, substitute xxxx and yyyy for your array names and password files.

I have script that will enumerate VMs on datastores, snap the VM then snap the array volume, others that will shutdown a VM and run an updateVV to refresh RDMs then power the VM back on. The CLI is very powerful. The only caution is the CLI does not return errors they way you would expect. Most CLI commands only retrun a non-zero error code if the command itself is incorrect. If you want to check the success of the actual command you need to script outputting the anticipated changes and scan code that with code to make sue the array did what you want. Also note that CLI commands are not alsway consistent from version to version as the CLI was not intended for scripting. There go forward scripting API is the web APIs winch I disagree with. Many administrators can write batch/scrip files, but writing xml/html is a different league.

So:

showvv > output.txt
or
showvv >> output.txt
