So I'm at home, doing some planned work this weekend, and its probably the most stressful thing I've had to do (that was planned, obviously unplanned outages can be very stressful). We have a 1TB SAP instance running on our XP storage array on a SLES10SP1 server. We need to migrate the data from LVM to Storage Foundation Disk groups/vxfs partitions to introduce the system into our new backup infrastructure. Our XP array is diced into 20GB LUNs, so this basically involved creating a Business copy of 50 LUNs, copying the data, splitting it off, installing Storage Foundation, blow away all the existing SAP/Oracle data and reinitialize the disks with Storage Foundation, zone the copied disks into the server, bring the old data online under different mount points, and copy all the data to the new disks. Of course theres a ton of extra steps in there I didn't list (like validating the data on the copied disks before wiping the originals, etc), but thats the short of it anyway. Oh, and I forgot to mention, no current backup of the instance because it would take around 4 hours to back it up and we don't have that long of a maintenance window, so the only copy of the data is the disk copy, and the Netbackup from last weekend (hardly possible to even use it). I about threwup when I had to wipe the data off the original disks as the maintenance window is only until 2am at which point everything has to be back online or we start losing gobs and gobs of money (as I've stated here before, something to the tune of $45,000 every 118 seconds). Fortunately, everything has been going smooth and the copy is taking place now but still... ugh. What have any of you done at work that was dangerous enough that it made you feel sick?
