Figure 84. Output f r o m splstdata -e
The locations (server hostname and directory) for user administration files are
also stored in the System Data Repository. These default values may be
changed. However, the /etc/passwd and /etc/security/passwd files are updated
from the Control Workstation. Therefore, if the master copy of these two files is
not located on the Control Workstation, the files must be copied to the Control
Workstation every time they are changed, so that the nodes will be updated with
the correct password information.
9.3.1 Adding an SP User
Before adding an SP user, ensure that the host which is serving user directories
(the Control Workstation in our case) has its /etc/exports file modified to grant
access to all hosts that need to mount the user
′
s home directory. For example,
add /home/sp21cw0 to /etc/exports on the Control Workstation and then run
exportfs -a
. If this is not done,
spmkuser
will return the following message when
adding a user (harry) on the Control Workstation (sp21cw0).
spmkuser: 0027-122 Warning: User directory, /home/sp21cw0/harry, is in an
unexported filesystem on sp21cw0.
