Corruption of the utmp file shows up in two ways:
- The uptime and w commands show a time greater than 8000 days since the system was last booted.
Users are shown as still logged in when in fact they are not.
Both types of corruption have many causes because both AIX commands and third party applications write to the utmp file.

 There are two ways:
add the following entries to /etc/system:
- Set all hme interfaces to 100MB full duplex
- set hme:hme_adv_autoneg_cap=0
- set hme:hme_adv_100T4_cap=0
- set hme:hme_adv_100fdx_cap=1
- set hme:hme_adv_100hdx_cap=0
- set hme:hme_adv_10fdx_cap=0
- set hme:hme_adv_10hdx_cap=0
- End hme interfaces
The above example will force all adapters on to 100mb full duplex
The other way is as follows:

mknod (device) c (major no) (minor no) Creates a /dev/ device file.
mknod /dev/null1 c 2 3
chdev -l (device) -a (attribute)=(new value) Change a device attribute
chdev -l sys0 -a maxuproc=80
rmdev -l (device) Change device state from available to defined
rmdev -l (device) -d Delete the device

1) Stop the xntpd daemon
The xntpd daemon is managed by the System Resource Controller (SRC).
To verify that the xntpd daemon is active : lssrc -s xntpd : status
should be "active"
To stop the xntpd subsystem : stopsrc -s xntpd
Note : xntpd is automatically started in /etc/rc.tcpip. To verify this :
cat /etc/rc.tcpip | grep xntpd.

Rebooting clears the utmp file and is the recommended method of correcting the results of corruption.
The following is an awk script that can be used to attempt to clean out bad entries in the /etc/utmp file. It may not clean certain types of corruption and a reboot will be required to clean up the file.
WARNING: Since the utmp file is constantly being changed, there is always the possibility that an attempt at correction (other than by rebooting) may corrupt the /etc/utmp file.

This process will require the krb5-client (it is best to install ALL of the packages), Samba, and Samba-Winbind.
Use the following steps in the order that they appear to join the SUSE client to the Windows 2003 Server domain. Any issues please use the Forum/shoutbox (for registered users ONLY - but it is free!) for additional help and assistance.
Step 1: Install the Required Packages - This can be done through Yast
Step 2: Edit the /etc/krb5.conf File
[logging]
default = FILE10000:/var/log/krb5lib.log
[libdefaults]
ticket_lifetime = 24000
default_realm = DOMAIN.INTERNAL
default_tkt_enctypes = des3-hmac-sha1 des-cbc-crc des-cbc-md5 aes256-cts arcfour-hmac-md5
default_tgs_enctypes = des3-hmac-sha1 des-cbc-crc des-cbc-md5 aes256-cts arcfour-hmac-md5
[realms]
DOMAIN.INTERNAL = {
kdc = domainserver.domain.internal
admin_server = domainserver.domain.internal
default_domain = DOMAIN.INTERNAL
}
[domain_realm]
.domain.internal = DOMAIN.INTERNAL

You can reduce file system fragmentation as follows:
- Copying the files to a backup media
- Recreating the file system using the mkfs fsname command or deleting the contents of the file system
- Reloading the files into the file system
For example, a system has a separate logical volume and file system hd11 (mount point: /home/op). Because we decide that file system hd11 needs to be reorganized, we perform the following steps:

Mirroring does not work with the BLV as it is not a true logical volume, bosboot must be run against the other disk after mirroring the rootvg.
bootlist -m (normal or service) -o displays bootlist
bootlist -m (normal or service) (list of devices) change bootlist
