We have two software caches but have noticed that in the CommVault\Simpana\SoftwareCache\CVUpdates\9.0.0 folder on each machine that they are not the same.
Local Software Cache has Unix, Windows, Windows64 and WinX64
Remote Software Cache has WinX64
So the remote software cache is missing some of the folders and Linux machines deployed using it are all missing the service packs.
The settings for the remote software cache are enabled and autosync is on and reports In Sync with the Commserve and package status is valid.
I have downloaded SP6a which has updated on the local cache and the one folder on the remote cache has updated however the Unix, Windows and Windows64 folders are still missing.
