Issue

  • Any of the plug-in deployments  to hosts for either install or upgrade fail with the following error, in the SnapManagerWeb_<JOB>.log:
ERROR SnapManagerWeb_18404 PID=[8624] TID=[17] Unable to find the SnapCenter supported plug-in packages.
ERROR SnapManagerWeb_18404 PID=[8624] TID=[17] Failed to get the supported plug-ins version map. Error: Value cannot be null.
ERROR SnapManagerWeb_18404 PID=[8624] TID=[17] Failed to calculate the plug-in compatibility status. Unable to find the supported plug-ins info.
 
  • The error happens despite:
  1. The package repository at %PROGRAMDATA%\NetApp\SnapCenter\Package Repository having all the plug-in installer files (Windows, Linux, AIX), their signature .sig files (4.8+), and including the oracle_checksum.txt and the snapcenter.config file.
  2. The registry entry at\HKEY_LOCAL_MACHINE\SOFTWARE\NetApp\SnapCenterServer correctly points to %PROGRAMDATA%\NetApp\SnapCenter
  3. The NSM repository database's table nsm_PluginPackages shows the correct version plug-ins with correct file reference in Repository_Path and with Downloaded set to (binary, single bit) 0x1.
  • May also see Upgrade Mandatory in the Status in the SC Hosts UI even though an upgrade was successful, and may see:
