Problem: 0315-132 The supplied error log is not valid: /var/adm/ras/errlog

When I tried to check errpt on an AIX 5.2 server, I got the following error.

# errpt
0315-132 The supplied error log is not valid: /var/adm/ras/errlog.
0315-180 logread: UNEXPECTED EOF
0315-171 Unable to process the error log file /var/adm/ras/errlog.

# ls -l  /var/adm/ras/errlog
-rw-rw-r--   1 root     system            0 Mar 09 13:40 /var/adm/ras/errlog

Solution:

1. Stop errdaemon

# /usr/lib/errstop

2. Remove /var/adm/ras/errlog

#  ls -l  /var/adm/ras/errlog
-rw-rw-r--   1 root     system            0 Mar 09 13:40 /var/adm/ras/errlog
# rm /var/adm/ras/errlog

3. Restart errdaemon

# /usr/lib/errdemon

4. Now errpt is normal.

# errpt
