GUI limitations

The following are the limitations of the IBM Spectrum Scale™ GUI:

1. The GUI supports RHEL 7.x, SLES 12.x, and Ubuntu 16.x on Intel x86, Power® (Big or Little Endian), and IBM Z platforms.
2. Up to 1000 nodes are supported.
3. The GUI supports a subset of the CLI functionality. Additional capabilities will be added in the future releases of the product.
4. The Object management panels do not support configurations with Keystone V2 API.
5. One GUI instance supports a single cluster.
6. In an IBM Spectrum Scale and Elastic Storage Server (ESS) mixed support environment, the ESS GUI must manage the whole cluster to display the ESS-specific pages in the GUI.
7. The GUI is not supported on the cluster that runs on IBM Spectrum Scale release earlier than 4.2.0.0. The GUI supports IBM Spectrum Scale release 4.2.0.0 or later. Issue the mmlsconfig command to see the value that is set for the minReleaseLevel attribute. Use the mmchconfig release=LATEST command and restart the GUI to make the management GUI fully operational at the new code level. As changing the minimum release level affects the cluster behavior, refer the mmchconfig command man page and other related topics before you make this configuration change.
8. The GUI node must be a homogeneous stack. That is, all packages must be of the same release. For example, do not mix the 5.0.0 GUI rpm with a 4.2.3 base rpm. However, GUI PTFs and efixes can usually be applied without having to install the corresponding PTF or efix of the base package. This is helpful if you just want to get rid of a GUI issue without changing anything on the base layer.
