Is there a way to export / import labels in and out of HCS?
I haven't seen a built in function. I've written some c# to extract and updates labels through the API, so you should be able to easily do it with the HiCommandCLI.
I've got a powershell script that exports LDEV & DP Pool stats via HiCommandCLI into CSV files and imports them into a SQL database for manupulation.
The HiCommandCLI command to output LDEV labels is
hicommandcli getstoragearray subtarget=LDEV -f csv -o <CSVfilename>
You can then manupulate the CSV file in excel to create an import using the following HiCommandCLI command
hicommandcli addlabel serialnum=<ArraySerial> model=<ArrayModel> devnums=<LDEV#> label="<YourLabel>"
