missing disks, dump devices, mirroring, etc. – Waldemar Mark Duszyk – Since, we are pretty much always learning …. Some of us on a more elementary, intermediate, or advanced level but regardless of the level we all always learn or re-learn (because what we have mastered we had an ample time to forget – not doing it for a while), here it is a reminder of how to deal with a volume group (in this case it is rootvg which for some reasons lost one of it disks. The loss could be a function of SAN, VIO or other event. It could be a permanent loss – a disk is dead, broken, no longer functioning or the loss was/is temporary in nature; AIX kernel detected a timeout (without any disk errors associated with device failure) long enough for the kernel to mark the disks missing.

Squid kerberos authentication and ldap authorization in Active Directory « Klaubert’s Blog – The squid web cache include a authenticator for kerberos, it is simple to use, but the documentation is not very clear about how to make it work.
