Domain Controller Down (VM)

Steps everyone else missed.
vCenter came up after the DC's so we restarted the vCenter Services.
Some of the VM's were running as zombie's (storage had dropped to long, OS had crashed) so the VM's had to be reset once storage came back up (Note APD detection in 5.5 and 6.x is better and this isn't as common).
Storage latency over 100Mbps iSCSI is awful. 500ms max on one VM, and average of 45ms. This is like running your hard drive remote from Houston to Atlanta. Hence my recommendation of some proper enterprise direct FC attached storage to deal with this mess.
This stuff isn't supported (and has NEVER been supported to use vMotion or iSCSI over 100Mbps) in the past 8 years I've worked with VMware.
As we discussed my home lab from 5 years ago was in a better state for availability and performance and supportability.

We just got access about the time you became available so it worked out well.

Among all the many things wrong, this right here is a killer thing. whoever set this up was nearly criminal.

Agreed. Slowly but surely changes will be made. Thank god for ML though. For real.

it's amazing that someone spent all that money on Cisco USCs but didn't put in any type of 1 GB switches.
-
@Dashrender I think I said word for word exactly what you said when i first started
-
They complain about slow network and they haven't approved a GB switch yet?

WTF??!?!

Looks like an ipod... This is going to be interesting in the long term. Those Cisco chassis can do some expending though so you may be able to get to a more reliable system with what you have.
Actually UCS can't really expand much from a storage perspective. They don't have any native DAS JBOD support, and the MegaRaids on them they do little in integration or customization. UCS was never really designed to use local storage in RAID I'm convinced (at scale anyways). They are useful if your using them in true JBOD (VSAN, they are certified for use) or with HBA's to talk to an external disk array.
Definitely not designed for that use.

@Dashrender I am. Thanks everyone. You guys really banded together to help me. I really really appreciate it.
You would have been here a lot sooner had you told people to go away and leave you alone. the time gaps in this thread are telling.
Yes, you should report this to management that you were hampered not only from lack of documentation and obviously having important information hidden... but that the existing people were fooling around like this was a joke to them.

Other thing is get some training. There's some rookie mistakes lurking in that config that scare me about other things...
http://vmware.stanly.edu is the poor mans path to a VCP. Grab a copy of mastering vSphere. The HA deep dive book is free now if you know where to look. and increasingly we'll have storage and availability documents lurking at storagehub.vmware.com

This is true... But getting some training is rarely a bad thing. 8-)

Alright, so I'm going to need to fix some DNS issues which I think @JaredBusch informed me of yesterday. When I perform
nslookupon my file server and printer server it kicks back an error stating:DNS request timed out.
Default Server: Unknown
Address: 192.168.10.16 <-- IP of my domain controller (2003) -

I agree. Training and documentation are key once this fire is fully out.
