iManager for Linux is required for managing eDirectory users. It can also be used to manage the OES Storage Services pools and volumes, OES Cluster Services for Linux clusters and cluster resources, OES CIFS, Novell Samba, and OES Linux User Management.
It is not necessary to install iManager on every server, but it must be installed somewhere in the same eDirectory tree. For information about installing and using iManager, see the NetIQ iManager Administration Guide.
You use the Storage plug-in for iManager to share devices and to create and manage NSS pools and volumes. For information, see Storage Plug-In Quick Reference
in the OES 2018 SP3: NSS File System Administration Guide for Linux. You can alternatively use NSSMU to manage NSS pools and volumes.
You use the Clusters plug-in for iManager to manage the DST pool cluster resource, and to modify the resource load script, unload script, and monitor script. For information, see Configuring and Managing Cluster Resources
in the OES 2018 SP3: OES Cluster Services for Linux Administration Guide.
