You can get NSS patches in the OES update channel or from the Micro Focus Download Web site.
Consider the following issues when updating NSS:
When you update an OES server with a Support Pack or apply NSS patches, all NSS-related parameter settings remain the same as they were before the update or patch. For example, server-level, pool, and volume settings are not modified.
If you do not reboot the server as part of the update or patch process, some NSS functions and tools might not work properly until you restart the jstcpd, adminusd, and volmnd daemons.
For example, NSSMU or the Distributed File Services (DFS) volume location database might hang when you create a volume. DFS is delivered and updated as a part of the NSS package on OES servers. If the server is a VLDB replica site, the vldb might not work properly or cause hangs when creating new NSS volumes. For information, see DFS may not function properly after upgrading NSS on OES 2 and later.
in the OES 2018 SP3: Distributed File Services Administration Guide for Linux.
To ensure that NSS and DFS is functioning properly after updating OES to a support pack or applying NSS patches:
Log in as the root user, then open a terminal console.
At the terminal console prompt, restart the following daemons in the order indicated:
/opt/novell/nss/sbin/jstcpd /opt/novell/nss/sbin/adminusd /opt/novell/nss/sbin/volmnd
If the server is a VLDB replica site for a Distributed File Services management context, restart the VLDB by entering,
vldb stop service
vldb start service
The File Protocols plug-in for the Native File Access Protocols for NetWare service has been replaced in OES 2 SP1 by two plug-ins: OES AFP (afpmgmt.npm) and OES CIFS (cifsmgmt.npm). These plug-ins support AFP and CIFS services for NSS volumes on both Linux and NetWare.
The AFP and CIFS plug-ins also require the NSS Management (nssmgmt.npm) and Storage Management (storagemgmt.npm) plug-ins. Other storage-related plug-ins include Archive Versioning (arkmgmt.npm), Cluster Services (ncsmgmt.npm), Files and Folders Management (fileman.npm), Samba Management (sambamgmt.npm), and Distributed File Services (dfsmgmt.npm). All storage-related plug-ins share code in common with the Storage Management plug-in.
You must uninstall the existing storage-related plug-ins, then install the new plug-ins at the same time to make sure that the common code works for all plug-ins.
