Symptoms

In the /var/opt/SUNWSMS/adm/platform/messages file on a Sun Fire[TM] 12K/15K/E20K/E25K SC, all components in the platform report FruAcess errors and "FRAD chkpt WRITE failed" messages such as the following:

The command showenvironment reports all temperature and voltage status checks are fine for all components, and nothing appears to be wrong on the platform, so why are all the messages occurring and how do we stop them?

Cause

The error message is indicating that FRAD, Fru Access Daemon, can not write to a checkpoint file because the daemon doesn't have permissions to the file.

Solution

In the case of the FRAD chkpt error, the file in question is located in the /var/opt/SUNWSMS/data/.failover/chkpt directory on the SC. This file is a checkpoint file that is used as reference by FOMD (Failover Monitoring Daemon) for file propagation between SCs.

If the permissions on this chkpt file are incorrect, the SMS daemon can not write to it and the error messages appear. So, a possible "fix" for this issue would be to simply open up the permissions on this file or directory and the daemons could now write to the chkpt file, as root does:

chmod -R 777 /var/opt/SUNWSMS/data/.failover/chkpt

BUT, this is not really a good solution because this may not actually be the real root cause. There might be more problems that need to be resolved.

If the directory /var/opt/SUNWSMS/SMS1.4.1/data/.failover has the wrong group/ownership permissions, it's subdirectories are not writeable by sms daemons, and the error messages above will happen.

Changing just the permissions on the chkpt files or chkpt directory is not the correct course of action, because we need to make sure that the parent directory is not actually the real root cause. The whole directory structure needs it's ownership configuration resolved to head off possible future issues:

Ultimately, changing the permissions on only the /var/opt/SUNWSMS/SMS1.4.1/data/.failover/chkpt directory would allow for SMS to write to the particular chkpt file, but there is no telling if other problems might be resolved now by fixing what was actually root cause, which is the bad group ownership of the top level directories.

So, the fix is to issue the commands as root:

cd /var/opt/SUNWSMS/SMS1.4.1/data
chgrp -R sms .failover
chgrp -R sms .cod

Please see Additional Information for more suggestions.

Additional Information
It is important to note that the group ownership issue could be the result of a tar restore or cpio restore that did not preserve original group and owner settings, or it might just be the result of someone having manually set these ownership/permission themselves for some reason. The fact is that it would be hard to prove either way after the fact. If one directory or file is configured incorrectly, assume all are.
Confirming the configuration is correct should be the next step. Obtain access to a separate "known good" SC to compare configuration, or log a case with Sun[TM] Support to obtain help in making sure permissions and ownership is correct.

It's also a good idea to confirm that the SMS daemons have the correct UID as well. From /etc/passwd, the UID is as follows for the various daemons:

sms-codd:x:10:54:SMS Capacity On Demand Daemon::
sms-dca:x:11:54:SMS Domain Configuration Agent::
sms-dsmd:x:12:54:SMS Domain Status Monitoring Daemon::
