Power routine
Another issue I would love to add is a proper shutdown procedure.
In today datacenter enviroments, is pretty common to have a mix of routers, firewalls, NAS, SAN, Vmware servers, backup servers, tape drives, email servers, database servers, UPS's, switches, Intrusion detection devices, Proxies, WAN accelerators, etc.
Some small datacenters can have all this equipment but lack of power generation equipment. In a case of extended power failure, power maintenance and other issues where you will have no power for several hours (or days) in the datacenter, You will need to shutdown all your equipment in the correct order and with the right procedure.
For example
1- never shutdown your domain controllers before shutdown Exchange first,
2- make full backup (if this is an scheduled power down) of all servers
3- turn off servers in the right order: for example if you have a Blackberry server (BES), turn it off before Exchange
4- turn off SAN devices at the end of the servers turn off routine
5- have proper docummentation of the power off routines for special devices like SAN, virtual disks and other devices in use by Virtual infrastructure (you definiitely do not want to turn off the SAN where the ESX servers have the data)
6- have docummentation of all ip addresses, login and passwords,
7- have a copy of the clients you will need to power on / power off your units (ie: vmware clients, san clients, etc)
8- consider to have a laptop with extended battery time in your site or office
9- list of all IT contacts, providers, etc
10- notify users about power disruption, in maintenances or emergencies
11- some ISP can cut your E1 links if your device are turned off fore some x time. I normally turn off all equipment but I have a big UPS able to provide enough juice to the router for about 8 days. In this way I avoid our ISP to cut our ring and have problems when power is back
Hope this works for you
