Service Bulletins PDF Print E-mail
Written by Michael Felt   

One of those areas on IBM's portal that has moved. The old one was still there, but it did not provide any information for TL8 and TL2, so finally got around to updating all that and added the new links in the menu on the right.

The new name is: Power Server Bulletins

Very useful to find information about recent updates and their impact! Visit every now and then and keep your AIX systems healthy.

is in the eating!

I reported that I had suffered for a few days getting everything running properly after a power failure of about 90 minutes. I cannot place direct blame on everything that went wrong on the power outage.

To a certain degree, everything worked very well. Once power was back, everything came back up, though a bit slow because of dependencies in the different systems (e.g., better if the name server is up before the database). But I have a odd collection of processors systems - which have been great for learning - but not so great for "unmanaged" restarts.

Or can you imagine even being excited by a 1200 BAUD modem?

Power Outage - Hangover PDF Print E-mail

Just a small update. Seems my NAS and an ethernet switch did not like the outage either. After 12 hours up, a disk died, and a few hours later a network port died - well - needed a hardware reset.
I hope all the surprises for me are behind me now.
I guess I should be happy I was at home and could go to my data center (read basement) and repair everything.
 
Power Outage surprises Netherlands PDF Print E-mail

Some things cannot be prevented by mere mortals - when a power distribution hub dies - so does power to many homes and services. So, the downtime we experienced is close to a force-majeure - even my mobile could not send/receive calls.
Anyway, servers are back up and everything seems to be functioning normally again. Thank you for your patience and understanding!
