Just FYI, this is what I use for patching. I have it setup on a cron schedule.

OK another snag. Bill's link never mentioned the possibility that this isn't an LVM partition (which it's not, it's ext) so my re-introduce command is wrong.
ug - I wonder if my SR is destroyed?
This bit missing from the Citrix documentation cost me at least 1 hour, but probably more like 2.
Hope things are working again?
About the documentation: Contribute back, tell them about the missing part.
Done.

Glad that things are back working. Sorry that I was only on telegram for most of this.

Many of the updates are cumulative, do you don't have to install them all from scratch.
That was I was discussing in my thread from a while back, that there is a specific order to do them
The conclusion of that thread was that XO was smart enough to do it and should always be used, but if you don't have XO running, what you found is the best alternative I think.

I was a little confused about how exactly to recover from a XS boot failure. Obviously the way you did it was able to get the VMs back up and running. That is good to know.
There is also a methodology to backup the entire XS system, including the VM metadata. This process is described here...
http://techblog.danielpellarini.com/sysadmin/steps-to-take-to-restore-xenserver-from-backup/In another linked article, he explains what is backup up in the metadata as:
"And by VM metadata I mean what drives are connected to what VM, the name of the drive, the network interfaces etc."I guess if you had a lot of custom settings for your VMs (tags, etc.) or a lot of stuff listed as metadata, it might be good to do such a backup.
This is something I am still a bit unclear on.

Or just have like 20+ VMs (hell I'd want that at more than 5 for sure). You don't want to be guessing what VDI (I just feel icky typing that) - I mean virtual disks - go with what VM. Plus, as you said, what adapters are there, etc.

So I popped in a new SD Card and installed XS 6.5 again. Went to do updates and decide to just start at the oldest and move my way upward. Well once I reached Sp1 suddenly there was about 35 more - no thanks, don't want to be here forever, already late enough.
Found this link: http://support.citrix.com/article/CTX138115
Updated June 14, 2016It shows that you can go Install > Sp1 > update 12 > update 24 > update 27 > update 29 > update 32 > update 33.
Many of the updates are cumulative, do you don't have to install them all from scratch.
Hope this saves someone some time.
This is what i did when upgraded past sp1, just installed about 3 or 4 cumulative updates.
Also, in the future you could save a backup of your XS install with vm/sr info to the local SR, or anywhere else, just in case. It is an option from #xsconsole
I do this before upgrading usually, and keep it there afterwards.
edit: ah wait, i see someone mentioned the xsconsole backups. -
This is the second time in two days I've read about XS console - what is the XS console? Do you mean, does Citrix mean, the XS host? Calling it a console is so..... weird.
But hey, they call the virtual disks that are attached to VMs VDIs - so what do I know?
-
The root console
The xsconsole

PIPE DOWN! Do you want your servers hearing you and crashing again?????

probably not

If someone can find you with that, you've got a real hacker on your hands!

Psst - give greenshot a try - it's a free screen capture utility that has cool bluring features for bluring whatever you don't want read.

@Dashrender Hope your having a better day today

I'm having an OK one. Now if we could just keep employees from quitting.

@MattSpeller contacts with ridiculous buyouts work well too.

In the vein of EXT vs LVM and LVM "partitions"....
In the directions, it says to find the SCSI ID of the device/partition where the SR data is stored.
Here is my list.
