A coworker asked me is I could whip up a script to convert hundreds of lines large 7-mode /etc/exports files into Clustered Mode Export Policies and client rules.

Of all the thousands of emails I sent to customers in 2013, I sent this code to most. I think I sent it to over 150 people last year.
People do a really crappy job of monitoring their backup applications, and if they have old snapshots in VMware. It doesn’t matter if you use Veeam, NetBackup, BEX, SMVI/VSC, manual scripts, or what. Anything that automatically makes snapshots and then deletes them has the chance to totally screw that crap up!
Biggest issues happen when snapshots aren’t cleaned up if they are left around.

It really pisses me off when I have to type passwords over and over and over again. Even more so when I am trying to do a ton of work or do a deployment and I need to do it.

NetApp’s snapdrive utility can help simplify out workflow, and reduce the amount of requests we get from the “Bob’s” of the world. This shows how you can do things like creating, presenting, formatting and mounting luns from your NetApp all with 1 command from the host!

I’ll go more into cleanup of old luns or old flexclones later on hpux and linux, but for now… here is how to remove disconnected luns from an HPUX server. Don’t forget to remove the lv/vg first.
