Adjusting SCSI Target ID in ESX Server 3 with iSCSI

emb — Wed, 26 Sep 2007 21:01:55 +0000

I had an issue with an iSCSI target LUN not being formatted as VMFS in ESX Server 3.0.X. The problem turned out to be on my side, but I ended up with a number of blank SCSI Targets under VI -> Configuration -> Storage Adapters. My SCSI Targets jumped from SCSI Target 2 to SCSI Target 9. This was not an ideal situation as I want all of the members of the DRS/HA cluster to have the same configuration. The way to fix up the SCSI Targets involves adjusting some of the configuration files on the ESX Server itself. First you need to move any and all running VMs off of the host you’re going to be working on and put it into Maintenance Mode.

Log into the service console as root.
cd /var/lib/iscsi and there are two control files there: vmkbindings, vmkdiscovery
temporarily disable iSCSI: esxcfg-swiscsi -d
kill the iSCSI software: esxcfg-swiscsi -k
edit both the vmkbindings and vmkdiscovery to remove the LUNs that are no longer valid. You can change the target ID as well if you want to move that around.
start iSCSI back up: esxcfg-swscsi -e
wait about 30 seconds and do a rescan from the command line: esxcfg-swscsi -s
once you do that you can go into the VI Client and rescan the Storage Adapters. If this looks right now you’re all set.
take the server out of maintenance mode and move a VM to the server to make sure it is working correct

That’s it! Good luck, this saved me a decent amount of time and I wasn’t able to find this information in the forums or on the interwebs.

As if you needed another reason to NOT watch the view..

They asked the new host of The View is she thought the world was flat. She honestly doesn’t KNOW if the world is flat or not. Watch her wiggle out of this one. Unbelievable. How can someone be this stupid?

Invalid Response

This has really just been my luck so far this week. I turn on our new Avocent MergePoint 5300 to start the configuration. Go into the configuration via the console port:

1:Summary
2:Network config
3:Set date and time
4:Set admin password
5:Reboot
6:Power off
7:Roll back the version
8:Security config
9:Debug Log
10:Restore to Factory Defaults
0:Exit
Please select [0 - 10]:

Fair enough, right? All I need to do is set up the IP address so I can jump into the configuration website so I select “Network Config”.

Set eth1 Speed:
1:Auto-Negotiate

Current Setting [Auto-Negotiate]
Please select [0 - 5]:1

Set eth1 DHCP?(Y/N):N

Apparently there is no known valid response. How does a product leave QA in this state? I already hate this thing and I haven’t even set it up yet.

This should be more obvious than it is: Launch “Internet Connect”, select “Options…” from the “Connect” menu and deselect “Send all traffic over VPN connection”.

Princess Bride is Twenty Years Old

One of my favorite movies (save your jabs for the comments section) Princess Bride is twenty years old. That makes me feel, well, old I guess. I saw this on Digg and the “Then and Now” pictures come via ABC News.

I was on the interwebs last night and came across a classic Craigslist posting. This one really got me because I can just imagine the entire scene in my head involving one of my drunk friends. I initially thought the guy was being sincere but when he called them “cripple sticks” he sort of lost me. I’ve included the entire post below because Craigslist rolls them off every week or so:

dear sir or madam:

at approximately 00:30 on thursday morning, i was with a friend walking back from a night of drunken revelry when i spotted a pair of crutches leaning against the fence by the tennis courts. you are evidently very tall, as i had to adjust these crutches before i could mockingly, drunkenly use them. i apologize for any inconvenience i caused you and would be more than happy to return your cripple sticks.

please respond at your earliest convenience. tell me what your crutches look like so i don’t give them to a cripple-poser.

This is the most random clip I’ve seen in a long time. I’m not sure what is more disturbing.. the clip or the comments from people about how funny it is. I was more horrified than anything.
