A SAN Admin's Worst Practices Guide
seb_ 060000QVK2 Visits (7525)
There are a lot of best practices guides out there. Some of them come from vendor's system engineers, technical consultants or tech sales. Other come from the target audience itself - mostly administrators, sometimes their managers or staff members of the CIO's office. And as they have different views on the topic they also have different opinions about best practices. A financially driven CIO has of course other priorities than the vendor. "Best" for one is not "best" for others.
And then there is support
You know what's the misery in a tech support member's life? We only see the bad things. People approach us when things burn. We're solving actual problems. Problems that are undeniably existent and they happen right now. If a hint from a best practice guide can help us to overcome such a situation, perfect. On the other hand it's pretty hard for us to decide which best practice is better on the long run, because... guess what... Nobody calls support if everything is fine. Well, that's definitely a statement I should qualify in another blog article, but let's take it like that for now...
We're experts for things going wrong
There is something support can add to the discussion and that is worst practices. Stumbling over the second client with a certain feature configured in a way it hurts makes us raise an eyebrow. Stumbling over the fifth one proves that there is either a systematic error or that we have something that's thought to be a best practice but in fact it's a worst practice. During my time in support I faced a lot of these situations.
So what I can do is to tell you about them in form of a series of blog posts, each one handling another worst practice. I'll tell you why it's a worst practice and what could or even will happen, if you follow it anyway. My goal is to provide food for thought for some things that should be avoided. I'll update this blog post every time I add a new worst practice.
Let me know what you think!
When you read them and you think "Hey, we do it that way and we have damn good reasons to do so!" or if you know of other worst practices in the realm of SAN administration and troubleshooting, please let me know.
