Troubleshooting DMS
This chapter contains information to assist you in troubleshooting problems
with DMS. If a DMS client has trouble booting, you can check several aspects
of server operation to ensure that the server’s end of the network connection
is functioning properly. These are grouped into the following categories:
Removing DMS lock files (Section 13.1)
Checking NFS server status (Section 13.2)
Checking network daemon status (Section 13.3)
Checking directory exports (Section 13.4)
Checking server-client compatibility (Section 13.5)
Correcting swap device problems (Section 13.6)
Reconfiguring for a hardware update release (Section 13.7)
13.1 Removing DMS Lock Files
To prevent multiple users from performing simultaneous operations on DMS
areas, the dmu utility creates two lock files in the /tmp directory, dmslock
and dms.tty.lock when you are installing or deleting software in a DMS
area. If another user (or the same user on a different terminal) runs the dmu
utility and attempts to install or delete software from the DMU Main Menu,
they see a message similar to the following:
The dmu utility is currently locked while j_smith on /dev/ttyp3
is installing software. Try again later.
If the dmu utility is stopped prematurely, these lock files may not be removed
and you see this message even though no other user is using DMS. You must
delete the lock files from the /tmp directory.
_____________________ Caution _____________________
Before deleting the lock files, ensure that no other user is using
the dmu utility.
