This appears to be a failed disk or RAID controller.  See the VMWare KB link.

That's a storage fault

1. Check you have supported storage controller.
2. Boot from Smart Start CDROM and run the Array Configuraton Utility and check the RAID array.
3. Do you have any flash amber lights on the disks.
4. Update firmware on controller and disks.

What's the RAID array, local disks or DAS attached?

Well, this setup is working for years. Last year i did upgrade on Vshpere 4.1 but never had an issue like this.

1. I think this is ok , i have 4 other host and had no issue ... i guess its  supported 99.9 % .
2. Well , i am waiting for closing of branches , then i can reboot atm vm's on host are working , just host is not responding.. ( but soon expecting to lose connectivity on vm's which resides on that host)
3. No i dont have any amber light , otherwise i would change broken part.
4. I am downlaoding firmware for dl390 g5 ... ( its 1gb gonna take 2 hrs more , hp limits bandwitdh i guess )

I have raid 1 on local SAS disks  , it 2 x 72 SAS disk.

disks do fail, they are mechanical.

you've not removed any shared storage?

its not problem , i am expection problems like this ...

There is not any changes on stroge side , actually one of storages acts strage but it would effect other hosts , but still is local issue i think.
This host crashed yesterday too , i didnt expect that its gonna repeat.After restart of host it keep working like 20 hrs.
it crashed yesterdey at 16PM and today again at 12:30 PM.

- Did last firmware upgrades , restarted and host wont boot :

But i moved vm's to other hosts everything is up and running :) . vm power ...
If i continue boot ( chceck image ) it stucks on   - mount root    while booting...

Should i do clean install again ... ? or keep tracking for for hardware failure ?

It looks like the OS partition has developed a fault.

Personally, I would destroy the installation, re-create the array.

I would install ESXi 4.1 on a USB flash drive, which the DL380 G5 supports, and dedicate the entire partition and disks to just a datastore.

Here is the VMware KB on installing 4.1 on USB/SD:

Here is the VMware KB on installing 5.0 on USB/SD:

You can if you want backup and have replacement flash drives on standby, see my article

How to Backup an ESXi installation on an USB Flash Drive or SD card, for security or redundancy.

and yes, ESX and ESXi 4.1 can co-exist in the same farm.

DR is much easier and quicker for ESXi!

(just put another USB flash drive in, and your  restore configuration back and done).

No issues there with ESXi 4.1 U1, or U2 in the same Farm. We are currently testing U2 in a farm of U1s, before finally upgrading all U1 to U2.

Go for it!

There is no service console on ESXi 4.1, it's been replaced with a VMKernel Port Management Network.
