+.SH NAME
+lctl-nodemap-set-sepol \- Set SELinux policy info on a nodemap.
+
+.SH SYNOPSIS
+.br
+.B lctl nodemap_set_sepol --name
+.RI < nodemap >
+.B --sepol
+.RI < sepol >
+.br
+.SH DESCRIPTION
+.B nodemap_set_sepol
+adds SELinux policy info as described by
+.I sepol
+to the specified
+.IR nodemap .
+The
+.I sepol
+string describing the SELinux policy has the following syntax:
+
+<mode>:<name>:<version>:<hash>
+
+where:
+.RS 4
+- <mode> is a digit telling if SELinux is in Permissive mode (0) or Enforcing
+mode (1)
+
+- <name> is the name of the SELinux policy
+
+- <version> is the version of the SELinux policy
+
+- <hash> is the computed hash of the binary representation of the policy, as
+exported in /etc/selinux/<name>/policy/policy.<version>
+.RE
+
+The reference
+.I sepol
+string can be obtained on a client node known to enforce the right SELinux policy,
+by calling the l_getsepol command line utility.
+
+Clients belonging to
+.I nodemap
+must enforce the SELinux policy described by
+.IR sepol ,
+otherwise they are denied access to the Lustre file system.
+
+.SH OPTIONS
+.I nodemap
+is the name of the nodemap that this SELinux policy info should be associated
+with.
+
+.I sepol
+is the string describing the SELinux policy that clients must enforce. It has
+to conform to the syntax described above.
+
+.SH EXAMPLES
