Our Storage Management group has been using HDvM (aka, device manager, HCS) for a couple years now. The ldev label feature is very popular here. To state the obvious it’s very helpful as a hook to search for. We use the labels extensively during migrations. Also for adding metadata about a device, like the application the ldev is used for, the VMware datastore name,the current use such as HUR_JOURNAL, DP_VOLUME.
There has been enough diversity in the application of these labels that I’m attempting to document a standard. I would like to start with
some guiding principles. I’m thinking along the lines of a list of rules that starting from the top filter down the use of label until you have a hit.
“For temporary use, no rules apply. Just be sure to inform the team of your intentions.”
“There is no need to add information that is readilyavailable already. A hostname in the label adds no information about an ldev that
is assigned to that host. ”
If you have any such rules or you have an ldev labeling policy I would be interested in anything you would like to share.
