I have linux bash scripts that probes each filer daily and obtains volume or other "Configuration" information , including comment , into a .csv file.
The .csv file is then converted into an html table.
The table has a very small amount of free jquery code which makes the "volume table" sortable by each column and search as you type BOX to filter the table down if your looking for something specific (kinda like grep across the entire table columns). I also put in an "EXPORT to CSV" button in case someone wants to pull any table/list over into excell.
Now, what I thought of would be a really easy way to retrofit a comment onto 7-mode volumes was this :
filer> wrfile -a /vol/vol33/.comment "Test Comment"
filer> rdfile /vol/vol33/.comment
Test Comment
filer>
My thought was then for the html / admin interface to allow a "volume" table across both which has an "editable" inline column for the comments. That way they could be created and edited in the admin part of the interface and updated.
I have not yet explored how to do this via the powershell toolkit and powershell but I am sure it can be done. Currently, all my files are bash scripts with lots of sed/awk simply running CLI commands , saving, and parsing. But I do plan to devote good part of 2017 to learning the netapp toolkit and powershell to see if I can convert my system over.
Mainly , I see the volume comment as a documentation tool and none of the NetApp GUI interfaces that I know of allow you to view or edit it. I don't think the dfm or ocu comments as serving this purpose and I like the fact when a comment follows the object , in this case , tied to the volume.
