I have read this document:
http://www.cisco.com/c/en/us/support/docs/servers-unified-computing/ucs-manager/110511-ucs-fw-mgmt-00.html
Specifically:
Image Delete
Here are some best practices to consider when you delete images:
-
You can use the UCS Manager GUI or the CLI in order to remove unused images.
-
Image deletion is asynchronous. When the administrator removes an image, the object is marked as “Deleted." The delete process performed in the background.
-
In the case of an HA cluster, images are automatically deleted on both fabric interconnects.
-
Packages are read only, and they cannot be deleted.
-
You can delete multiple images in either the UCS Manager GUI or CLI:
-
Select multiple images in GUI.
-
Execute the delete image command in the CLI.
You can delete by type or version. For example, this command deletes all images versioned as 1.1(0.47):
delete image version 1.1(0.47)
But I'm still a little lost on a few concepts.
-
The doc says "A package cannot be deleted. Packages are automatically purged when all the images that are part of the package are removed." - Yet inside UCS Manager I CAN select a package and choose delete. Is this semantics and it is really deleting all of the images in the package and then removing the package?
- What is the proper way to do clean up of old packages/images? I see them marked as "Active" in packages. Is there a way to understand what is and isn't being used? For instance if I have packages that are the "backup versions" on devices, can I safely remove them from UCS at that point?
Maybe I'm reading too much into it...and I have plenty of free space on the FI's, but if I can do some spring cleaning, I will.
