Does AIX support passwords longer than 8 characters? Yes!
Prior to AIX 5.3 TL7 and AIX 6.1,
there was an 8 character limit on AIX user passwords. If you need passwords of
greater than 8 characters then you must enable one of the supplied Loadable
Password Algorithms (LPAs). The following table lists the available algorithms
and the limitations of each: For example, to enable the MD5 algorithm
I can modify /etc/security/login.cfg file with the chsec command as follows:
# chsec -f
/etc/security/login.cfg -s usw -a pwd_algorithm=smd5 # tail -2
/etc/security/login.cfg

Replicated rootvg, ghostdev and NPIV
My team and I have recently
been trying to stream line our AIX disaster recovery process. We’ve been
looking for ways to reduce our overall recovery time. Several ideas were tossed
around such as a) using a standby DR LPAR with AIX already installed and using
rsync/scp to keep the Prod & DR LPARs in sync and b) using alt_disk_copy
(with the –O flag for a device reset) to clone rootvg to an alternate disk
which is then replicated to DR. These methods may work but are cumbersome to
administer and (in the case of alt_disk_copy) require... [More]
