Is your ESX server boot from SAN or from Local disk ?

if it is from SAN, did you check if the SAN is available

if you are booting from Local disk.. your boot partition seems to be issue..

you may be able to start ESX in safemode and see your grub file info.. and comapre with another same file from same model server

Hello,

If this is Boot From SAN, did you eanble the BIOS within the HBA.

If this is NOT boot from SAN did you disable the BIOS within the HBA

Also is LSI LOGIC SAS1068E on the HCL?

we have blade servers dell m600 and EMC. we have installed esx3.5 locally on all blade servers and all virtual station on EMC. I don't have issue with Virtual station.

But I have realize esx3.5 servers is giving us problem to boot up whenever light cut off suddenly

I have seen this error in 2 servers. As i said, i can boot the server in troubleshooting mode. Fortunate, i have solve this problem to run this command esxcfg-boot .

We are new in VM Ware. I would like to know what the cause of this problem.

Thanks

It actually sounds like you have installed boot from SAN and not boot from local disk. When you installed ESX on the M600 did you remove the fibre cables from the device or disable zoning/presentation from within the SAN?

We can see this by looking at the output of a few commands:

esxcfg-vmhbadevs -q

esxcfg-mpath -l

I belive you are not able to log in to the ESX system to run any of these commands..

so do these

- on boot get to QLogic Bios and disable the SAN

and if it is AMD processor check the advanced options and enable AMD Virtualization, Linux HFET (somje thing like this)

and reboot.. and see if you can boot successfully.

if it is Intel processor.. there must be similar settings..

thanks for reply,

i have checked, i have disconnected the SAN Fiber cable, but still my server is booting. It has cleared that i have not install vmvare on SAN.

Thanks
