Storage boot is slower then ESX boot

[dingding]

Sometimes, power outage occured in my datacenter, after power is resumed, the ESX, Storage booted at the same time, but my storage boot process is slower than ESX boot, so some ESX can't see the VMFS and VMs can't boot. if i reboot the ESX, all is OK. i just want to know if there exists some method to make the ESX boot wait until storage is totally ready.

Hello,

Instead of using the built-in tools for starting VMs you could add code to /etc/rc.d/rc.local to rescan the storage and if its available then start the VMs. Other than this, I have not seen anything that will delay the ESX scan for LUNs.

Another option is to use a 'boot server' that will wait until the storage is booted then boot the ESX hosts using wake on LAN or something like that perhaps use the same server to properly shutdown things when a UPS comes online.....

However another option is to use the features of some of the PDUs out there. Mine allow me to delay when power is applied to the socket so that I can boot hosts after others come up. APC PDUs have this feature.

Is there another simple possibility.

Edit the /etc/grub.conf and modify the value "timeout=10"

Change with a value that let the time for San to start properly.

I have a timeout of 300 second

really simple, and i can press enter to continue if i don't want wait
