General update and a long weekend ahead

Date June 5, 2009

After a week of wrestling with CDW and EMC, two weeks of fighting the storage array, and coming up with an ad hoc environment in something like 2 hours, I’ve had a rough go of this whole backup-site-activation thing.
The latest wrinkle has been that although EMC shipped us the storage processor, the burned CD [...]

The god of storage hates me, I know it

Date June 2, 2009

It seems like storage and I never get along. There’s always some difficulty somewhere. It’s always that I don’t have enough, or I don’t have enough where I need it, and there’s always the occasional sorry-we-sold-you-a-single-controller followed by I’ll-overnight-you-another-one which appears to be concluded by sorry-it-won’t-be-there-until-next-week. /sigh
So yes, looking back at my blog’s RSS feed, [...]

Followup to slow SAN speed

Date May 27, 2009

I mentioned this morning that I was having slow SAN performance. I said that I’d post an update if I figured out what was wrong, and I did.

SAN performance issues with the new install

Date May 27, 2009

So, you would think that 12 spindles would be…you know…fast.
Even if you took 12 spindles, made them into a RAID 10 array, they’d still be fast.
That’s what I’d think, anyway. It turns out, my new EMC AX4 is having a bit of a problem. None of the machines hooked to it can reach [...]

Obtaining the WWPN of fibre channel HBAs

Date May 9, 2009

Last week, I installed all of the equipment in our beta site. Due to issues with the power at my office, I wasn’t able to touch the blades for the month or so before they went in the rack, and the last time they were powered on, I didn’t have the storage array to make [...]

Resizing storage LUNs in Linux on the fly

Date May 2, 2009

I’m in the office working today and I figured out the best way (for me, anyway) to resize SAN LUNs without rebooting the server. I figured that I should document it.
To paraphase Linus, Only wimps use internal wikis: _real_ men just document their important stuff on blogs, and let the rest of the world [...]
